I've built a forum-like app in ColdFusion and I want to add a feature with which the users can upload files to Google Docs using their Google accounts and then other users can edit those files.
I've been using this CFC: http://cfgoogle.riaforge.org/ to retrieve Google Docs, but the upload function is currently missing. I need the upload function for the first upload of the file and then for the second part of editing it. I hope that it makes sense.
That's what I'm asking help for. I'm not that experienced with cffunctions and I was wondering if someone could give me a hand with it.
This is what I have so far:
<cffunction name="upload" access="public" returnType="any" hint="I upload the document." output="false">
<cfargument name="myFile" type="string" required="true" hint="file to upload.">
<cfset var result = "">
<cfset var service = variables.docservice>
<cfset theUrl = "https://docs.google.com/feeds/documents/private/full HTTP/1.1">
<cfhttp url="#theURL#" method="post" result="result">
<cfhttpparam type="header" name="Authorization" value="GoogleLogin auth=#getAuth(service)#">
<cfhttpparam type="header" name="Content-Length" value="81047">
<cfhttpparam type="header" name="Content-Type" value="application/msword">
<cfhttpparam type="header" name="Slug" value="#myFile#">
</cfhttp>
<cfreturn result.filecontent>
</cffunction>
But I get the following error when I output the result:
'Invalid request URI'
If someone could help me out with this one (even just show me the way), it would be mostly appreciated.
I would try to expand cfgoogle CFC with upload method using Protocol Guide for uploading.

We have ColdFusion tasks defined like this:
<cfschedule
action="update"
task="Test"
operation="HTTPRequest"
url="#path.getFileFolder()#tasks/test.cfm"
startDate="#now()#"
startTime="00:00"
interval="daily"
resolveURL="no"
publish="yes"
file="test.txt"
path="#path.getLogFolder#"
eventHandler="tasks.eventHandler"
onException="invokeHandler">
The onError function in the eventHandler looks like this:
<cffunction name="onError" returntype="void">
<cfargument name="context" type="struct" required="false" />
<cfscript>
var slackHookURL = 'urlToOurSlackErrorChannel';
var slackMessage = 'ourSlackMessage';
</cfscript>
<cftry>
<cfhttp url="#slackHookURL#" method="post" result="httpResp" timeout="60">
<cfhttpparam type="header" name="Content-Type" value="application/json" />
<cfhttpparam type="body" value="#slackMessage#" />
</cfhttp>
<cfcatch></cfcatch>
</cftry>
</cffunction>
We had the problem that after a server switch our config file missed a / in the file folder path. So the url referenced in all of our tasks pointed to something like https://ourPagetasks/test.cfm instead of https://ourPage/tasks/test.cfm. The onError function hasn't been fired. We just "accidentally" stumbled upon all our tasks not having been executed ever since.
In the test.txt log file however we found the message "Connection timeout". Shouldn't the onError function warn us if that happens? Or is there any workaround so I can check the text that's about to be written to the log file? The onTaskEnd function of the eventHandler is only allowed to have the parameter context which tells me nothing about what's going to be logged.
I hope I explained my problem somehow understandable. Thanks in advance!
I managed to implement a workaround. In our scheduledTasks.cfm I added the following lines at the end to check if any of the urls are invalid:
<!--- Check if the tasks are defined correctly --->
<cfschedule action="list" mode="server" result="tasks" />
<cfloop query="tasks">
<cfhttp method="head" url="#tasks.URL#" />
<cfif len(cfhttp.errorDetail)>
<cfscript>
slackHookURL = 'urlToOurSlackErrorChannel';
slackMessage = 'ourSlackMessage';
</cfscript>
<cftry>
<cfhttp url="#slackHookURL#" method="post" result="httpResp" timeout="60">
<cfhttpparam type="header" name="Content-Type" value="application/json" />
<cfhttpparam type="body" value="#slackMessage#" />
</cfhttp>
<cfcatch></cfcatch>
</cftry>
</cfif>
</cfloop>
We're upgrading to Google's reCaptcha and it adds a field with name "g-recaptcha-response" to the form during submit. We them need to verify the response to Google with code like this:
<cfhttp url="https://www.google.com/recaptcha/api/siteverify" method="post" result="captchaResult">
<cfhttpparam type="formfield" name="secret" value="SECRET">
<cfhttpparam type="formfield" name="response" value="#Form.g-recaptcha-response#">
<cfhttpparam type="formfield" name="remoteip" value="#CGI.REMOTE_ADDR#">
</cfhttp>
However, the #Form.g-recaptcha-response# gives Element G is undefined in FORM.
Is there another way to reference Form scope to allow hyphens?
That will give you an error if the form variable doesn't exist. Try this instead:
<CFSET Form.Response = "">
<CFIF StructKeyExists(Form, "g-recaptcha-response")>
<CFSET Form.Response = form["g-recaptcha-response"]>
</CFIF>
I wrote a reCAPTCHA v2 UDF yesterday. I wanted to support sToken so I could use the same API key on multiple websites.
http://gist.github.com/JamoCA/c4e83ca402bd6175a1d7
Just found a solution:
<cfhttpparam type="formfield" name="response" value="#Form["g-recaptcha-response"]#">
I started to work on Google Drive API with ColdFusion and I am stuck to upload the file using ColdFusion. I have done with the registration of new project, getting client and client secret and I am successfully able to get the accessToken but somehow I am not able to upload the file on the google drive.
Here is the code to get the code and accesstoken
<cfoutput>
<cfset request.oauthSettings = {
scope = "https://www.googleapis.com/auth/drive", client_id = "clientid",
client_secret = "clientsecret",
redirect_uri = "link"}
/>
<!--- create login url --->
<cfset loginURL = "https://accounts.google.com/o/oauth2/auth?scope="
& request.oauthSettings["scope"]
& "&redirect_uri=" & request.oauthSettings["redirect_uri"]
& "&response_type=code&client_id=" & request.oauthSettings["client_id"]
& "&access_type=offline"
/>
Login with Google account that has access to analytics
<cfif isDefined("URL.code") AND URL.code NEQ "access_denied">
<cfhttp url="#arguments.gaOauthUrl#" method="post">
<cfhttpparam name="code" type="formField" value="#arguments.code#">
<cfhttpparam name="client_id" type="formField" value="clientid">
<cfhttpparam name="client_secret" type="formField" value="clientsecret">
<cfhttpparam name="redirect_uri" type="formField" value="link">
<cfhttpparam name="grant_type" type="formField" value="authorization_code">
</cfhttp>
</cfif>
</cfoutput>
I am using the following code to upload the file, I know I have to pass some more parameters to make it correct but I don't know what are that parameters.
<cfhttp url="https://www.googleapis.com/upload/drive/v2/files?uploadType=media" method="post">
<cfhttpparam name="Content-Type" type="formField" value="text/plain">
<cfhttpparam name="Authorization" type="formField" value="#session.ga_accessToken#">
</cfhttp>
I am trying to find out in the google docs but no luck; there is no documentation for ColdFusion. Please let me know the other parameters if someone has some clue about this area.
You aren't setting the Authorization header correctly. It should be
Authorization: Bearer ya29.AHES6ZRosLBEnyGGH9EysIrAB7Z
*NEW UPDATED FOR BETTER SECOND PART - NOW GETS TO "308 Resume Incomplete", even though file should be just one upload!
I am using the foundation of cfgoogle from Ray Camden. But Google has deprecated the code for document uploads. The new standard is Resumable Media Uploads.
I have this part working (up to and including the "Initiating a resumable upload request") in the above referenced Google document.
Calling Page:
<cfset application.cfc.Google = createObject('component','#path_cf_cfc#Google') />
<cfset application.cfc.GoogleDocs = createObject('component','#path_cf_cfc#GoogleDocs') />
<cfset gtoken = application.cfc.GoogleDocs.authenticate(emailaddress,password)>
<CFSET testdoc = "a\filepath\documentname.doc">
<CFSET FileType = "application/msword">
<CFSET FileTitle = "test_001">
<cfset temp = application.cfc.GoogleDocs.upload_auth("#Application.Map.DocStorage##tv.testdoc#",FileType,FileTitle)>
<CFSET uploadpath = Listgetat(Listgetat(temp.header,ListContains(temp.header,"https://docs.google.com","#chr(10)#"),"#chr(10)#"),2," ") >
<cfset temp2 = application.cfc.GoogleDocs.upload_file("#Application.Map.DocStorage##tv.testdoc#",FileType,FileTitle,uploadpath)>
The code works up to and including the cfset temp line (getting the unique upload URI)
Here is the code for upload_auth:
<cffunction name="upload_auth" access="public" returnType="any" hint="I get a uniqu URI from Google API." output="false">
<cfargument name="myFile" type="string" required="true" hint="filepath to upload.">
<cfargument name="myType" type="string" required="true" hint="application/msword">
<cfargument name="myTitle" type="string" required="true" hint="name of doc">
<cfset GoogleUrl = "https://docs.google.com/feeds/upload/create-session/default/private/full">
<cfset GoogleVersion = 3>
<cfset FileSize = createObject("java","java.io.File").init(myFile).length()>
<cfhttp url="#GoogleUrl#" method="post" result="diditwork" resolveurl="no">
<cfhttpparam type="header" name="Authorization" value="GoogleLogin auth=#getAuth(variables.docservice)#">
<cfhttpparam type="header" name="GData-Version" value="#GoogleVersion#">
<cfhttpparam type="header" name="Content-Length" value="0">
<cfhttpparam type="header" name="X-Upload-Content-Type" value="#myType#">
<cfhttpparam type="header" name="X-Upload-Content-Length" value="#FileSize#">
<cfhttpparam type="header" name="Slug" value="#myTitle#">
</cfhttp>
<cfreturn diditwork>
</cffunction>
OK - So Far So Good.
But here is where it breaks down:
Running upload_file returns "308 Resume Incomplete" (A lest it's not a 400!) from Google. Arrgh!!
Here is the upload_file -
<cffunction name="upload_file" access="public" returnType="any" hint="I upload the document." output="false">
<cfargument name="myFile" type="string" required="true" hint="filepath to upload.">
<cfargument name="myType" type="string" required="true" hint="like application/msword">
<cfargument name="myTitle" type="string" required="true" hint="name of doc">
<cfargument name="myAuthPath" type="string" required="true" hint="call auth">
<cfset FileSize = GetFileInfo(myFile).size >
<CFSET tv.tostartwithzero = FileSize - 1>
<CFFILE action="read" file="#myfile#" variable="FileText">
<cfhttp url="#myAuthPath#" method="put" result="diditwork" resolveurl="no" multipart="yes" charset="utf-8" >
<cfhttpparam type="header" name="Authorization" value="GoogleLogin auth=#getAuth(variables.docservice)#">
<cfhttpparam type="header" name="GData-Version" value="#variables.GoogleVersion#">
<cfhttpparam type="header" name="Content-Length" value="#FileSize#">
<cfhttpparam type="header" name="Content-Range" value="bytes 0-#tv.tostartwithzero#/#FileSize#">
<cfhttpparam type="header" name="Content-Type" value="#myType#">
<cfhttpparam type="body" value="#trim(FileText)#">
</cfhttp>
<cfreturn diditwork>
</cffunction>
So, there we have it - where I am stuck.
I can get the unique URI, but (maybe because it is late at night) I'm brain dead on what I am doing wrong otherwise to complete the file upload.
All help is appreciated.
I strongly recommend taking a different approach here. There are two big issues with the path you're taking:
It appears the code is using the deprecated client login auth mechanism and is using the username/password instead of OAuth.
Using the deprecated documents list API instead of the newer Drive API.
Since you can call java, I'd suggest writing the upload code in plain Java then invoking it from your CF pages as needed.
Ive been given a class file from another group of SFDC developers that work in a separate instance that generates a SOAP based WSDL. I have imported that class file and generated the WSDL in our instance. The webservice is very basic, it just returns a set of values (in XML of course) and doesn't require any arguments to retrieve those values.
Just to test that the WSDL is working Ive downloaded the WSDL from our instance to my local PC and put it into SOAPUI and successfully returned the set of values.
NOW ONTO THE ISSUE - CONSUMING VIA THE URL
Im using Coldfusion's CFHTTP, so I have two CFHTTP calls, the first is to the login of our instance which returns a valid session ID. This session ID is used in my second call which is below:
<!--- token from from first cfhttp --->
<cfset variables.access_token_node = xmlSearch(XMLContent, "//*[name()='sessionId']") />
<cfset variables.access_token = variables.access_token_node[1].xmlText>
<cfset variables.wsdl_url2 = "https://cs12.salesforce.com/services/wsdl/class/WS_FAKE_WSDL">
<cfset packet = CreateObject("java", "java.lang.StringBuffer") />
<cfset packet.append('<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://soap.sforce.com/schemas/class/WS_FAKE_WSDL">') />
<cfset packet.append('<soapenv:Header>') />
<cfset packet.append('<ws:SessionHeader>') />
<cfset packet.append('<ws:sessionId>#variables.access_token#</ws:sessionId>') />
<cfset packet.append('</ws:SessionHeader>') />
<cfset packet.append('</soapenv:Header>') />
<cfset packet.append('<soapenv:Body>') />
<cfset packet.append('<ws:DescribesObjectFields/>') />
<cfset packet.append('</soapenv:Body>') />
<cfset packet.append('</soapenv:Envelope>') />
<cfhttp method="post" url="#variables.wsdl_url2#" result="findResponse2">
<cfhttpparam type="HEADER" name="Accept" value="application/soap+xml, application/xml, multipart/related, text/*">
<cfhttpparam type="HEADER" name="ACCEPT-ENCODING" value="application/soap+xml">
<cfhttpparam type="HEADER" name="CONNECTION" value="Keep-Alive">
<cfhttpparam type="HEADER" name="SOAPAction" value="dummy">
<cfhttpparam type="HEADER" name="Content-Type" value="text/xml; charset=utf-8">
<cfhttpparam type="HEADER" name="Must-Understand" value="1">
<cfhttpparam type="Header" name="Content-Length" value="#len(trim(packet.ToString()))#">
<cfhttpparam type="body" value="#packet.ToString()#" encoded="yes">
</cfhttp>
Below is what I am receiving from the WSDL..that code just takes me back to the login screen. With a Session ID I would assume I wouldn't need to log back in, correct?
All advice is appreciated.
You appear to be sending your APi call to the URL of the WSDL file, this is not the correct URL, you should be sending it to the service address that's detailed within the WSDL file, see the soap:address element in the service element at the bottom of the WSDL.
