I am trying to login to MySQL via C++ code using building connector c++, here is my code with my password removed:
std::string url = "mysqlx://localhost:3306/license_db?user=licuser&password=**********";
Session mySession(url);
mySession.sql("use license_db").execute();
auto result = mySession.sql("SELECT * FROM product").execute();
Row row1 = result.fetchOne();
The code causes an exception on the "Session mySession(url);" line and the exception says "bad allocation".
Can anybody help?
The URI is usally mysqlx://user:password#host:3306/schema for X DevAPI, whih works for JS, PHP, and Python.
There is an example at https://dev.mysql.com/doc/x-devapi-userguide/en/database-connection-example.html for C++
var mySession = MySQLX.GetSession("server=localhost;port=33060;user=user;password=password;");

Well i'm a student , and i'm still learning the dart language and the flutter framework, I was trying to make an application that makes you able to login into a site with a http post request and get data by manipulating the response of the html source code with some regular expressions to get what you need from the website,
(something like data scraping)
I tried to do that but nothing worked as planned.
I did this project! years ago and it was for desktop, with vb.net, I used a library called xNet which helped me to do that.
For this case I used the http dart package.
Is this kind of work can be done with dart?
Is there any specific packages for this?
Is there any docs available ?
I know html is not a regular language, i asked if it is possible to use http requests to login into a site!?
if i can do that i can manipulate the response and get what i need with some regular expressions.
I wanna do something like
C#
using (HttpRequest req = new HttpRequest())
{
req.UserAgent = Http.ChromeUserAgent;
req.Cookies = new CookieDictionary(false);
req.Proxy = null;
req.IgnoreProtocolErrors = true;
req.AddParam("login", cin.Text);
req.AddParam("no_anti_inject_password", pass.Text);
try {
string Respo = req.Post("http://www.example.com/login.php").ToString;
// to with that 'Respo'
if (Respo.Contains("disconnect"))
{
//Logged
//example
Match NAME = Regex.Match(Respo, "(.*?)");
name.Text = "Name: " + NAME.Groups(1).Value;
}else{
//not logged
//some code...
}
catch{
//some exception
}
}
HTML is not a regular language and so a regular expression is not a good way to scrape data from html. You may be interested in package:html which implements an HTML parser.
I am using parse sdk for backend management for my game. For user signup/login parse api ask for parameter tokenExpiration. I have no idea how to get it from facebook unity sdk.
https://www.parse.com/docs/unity_guide#fbusers-signup
Task<ParseUser> logInTask = ParseFacebookUtils.LogInAsync(accessToken, userId, tokenExpiration);
Got this problem solved by myself using debug_token. Here is the right code on how to do it.
FB.API("/debug_token?input_token="+FB.AccessToken+"&access_token="+FB.AccessToken,Facebook.HttpMethod.GET, AccessTokenCallback);
function AccessTokenCallback(response:String){
Debug.Log(response);
var access = JSON.Parse(response);
Debug.Log("Token Expiration is: "+access["data"]["expires_at"].Value);
}
If you will print the response it will give you a JSON with all information about the access token and you can take whatever info you need about an access token.
Open FacebookAccessTokenEditor.cs and replace original line 81:
formData["batch"] = "[{\"method\":\"GET\", \"relative_url\":\"me?fields=id\"},{\"method\":\"GET\", \"relative_url\":\"app?fields=id\"}]";
by these two:
string getExpiresAt = ",{\"method\":\"GET\", \"relative_url\":\"debug_token?input_token="+accessToken+"\"}";
formData["batch"] = "[{\"method\":\"GET\", \"relative_url\":\"me?fields=id\"},{\"method\":\"GET\", \"relative_url\":\"app?fields=id\"}"+getExpiresAt+"]";
Then open FacebookEditor.cs and in method MockLoginCallback, just before line 220:
isLoggedIn = true;
insert the following lines:
var tokenData = (Dictionary<string, object>)MiniJSON.Json.Deserialize(responses[2]);
var expiresAt = (long)((Dictionary<string, object>)tokenData["data"])["expires_at"];
accessTokenExpiresAt = FromTimestamp((int)expiresAt);
also, add the missing function FromTimestamp which you can copy from AndroidFacebook.cs or IOSFacebook.cs or jus copy from here:
private DateTime FromTimestamp(int timestamp)
{
return new DateTime(1970, 1, 1, 0, 0, 0, 0).AddSeconds(timestamp);
}
Finally, you can call the parse method like you do on IOS or Android or Web:
Task<ParseUser> logInTask = ParseFacebookUtils.LogInAsync(FB.UserId, FB.AccessToken, FB.AccessTokenExpiresAt);
Note: As I have worked on the code, I am not sure of the original line numbers, but I think they are correct. Also, this does not reflect the best coding practices, but since it is used only in a debug context, they're good enough for me.
I've had a scout around and can't seem to find the answer anywhere, so need to ask.
I'm trying to query the WMI on a remote machine, but I need to do so as the admin account and I'm having problems doing so.
The code I am using is:
Public Sub OperatingSystem(ByVal computeritem As String)
'set Username and Password which system will access the network with.
Dim options As ConnectionOptions
options = New ConnectionOptions()
options.Authority = "ntdlmdomain:" & ipaddress
options.Username = "Username"
options.Password = "Password"
scope = New ManagementScope("\\" & ipaddress & "\root\cimv2", options)
scope.Connect()
Dim query As ObjectQuery
query = New ObjectQuery("SELECT * FROM Win32_OperatingSystem")
Dim searcher As ManagementObjectSearcher
searcher = New ManagementObjectSearcher(scope, query)
the query continues to go and pull all kinds of information through to a spradsheet.. well it would if it worked!
The line of code that is falling over is:
scope = New ManagementScope("\\" & ipaddress & "\root\cimv2", options)
scope.Connect()
It's giving me an error message that just says 'Invalid parameter'. When I go to view detail, there's nothing in inner exception and the only thing that I can see of any value is ErrorCode:ManagementStatus.InvalidParameter
I apologize if this is something really simple.. I am still fairly new to this but if someone could give me some guidance that would really be appreciated.
Many Thanks.
It looks like the reference to ipaddress is not initialized. Since computeritem is passed as a parameter to the sub, your code might work better with:
scope = New ManagementScope("\\" & computeritem & "\root\cimv2", options)
I am hoping someone can help get me in the right direction...
I am using Powerbuilder 12 Classic and trying to consume a Oracle CRM OnDemand web service.
Using Msxml2.XMLHTTP.4.0 commands, I have been able to connect using https and retrieve the session id, which I need to send back when I invoke the method.
When I run the code below, I get the SBL-ODU-01007 The HTTP request did not contain a valid SOAPAction header error message. I am not sure what I am missing??
OleObject loo_xmlhttp
ls_get_url = "https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=login"
try
loo_xmlhttp = CREATE oleobject
loo_xmlhttp.ConnectToNewObject("Msxml2.XMLHTTP.4.0")
loo_xmlhttp.open ("GET",ls_get_url, false)
loo_xmlhttp.setRequestHeader("UserName", "xxxxxxx")
loo_xmlhttp.setRequestHeader("Password", "xxxxxxx")
loo_xmlhttp.send()
cookie = loo_xmlhttp.getResponseHeader("Set-Cookie")
sesId = mid(cookie, pos(cookie,"=", 1)+1, pos(cookie,";", 1)-(pos(cookie,"=", 1)+1))
ls_post_url = "https://secure-ausomxxxx.crmondemand.com/Services/Integration/Activity;"
ls_response_text = "jsessionid=" + sesId + ";"
ls_post_url = ls_post_url + ls_response_text
loo_xmlhttp.open ("POST",ls_post_url, false)
loo_xmlhttp.setRequestHeader("COOKIE", left(cookie,pos(cookie,";",1)-1) )
loo_xmlhttp.setRequestHeader("COOKIE", left(cookie,pos(cookie,";",1)-1) )
ls_post_url2 = "document/urn:crmondemand/ws/activity/10/2004:Activity_QueryPage"
loo_xmlhttp.setRequestHeader("SOAPAction", ls_post_url2)
loo_xmlhttp.send()
ls_get_url = "https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=logoff"
loo_xmlhttp.open ("POST",ls_get_url, false)
loo_xmlhttp.send()
catch (RuntimeError rte)
MessageBox("Error", "RuntimeError - " + rte.getMessage())
end try
I believe you are using incorrect URL for Login and Logoff;
Here is the sample:
https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=login
https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=logoff
Rest of the code looks OK to me.
I have run into similar issues in PB with msxml through ole. Adding this may help:
loo_xmlhttp.setRequestHeader("Content-Type", "text/xml")
you need to make sure that the your value for ls_post_url2 is one of the values that is found in the wsdl file. Just search for "soap:operation soapAction" in the wsdl file to see the valid values for SOAPAction.
I am trying to generate a vCalendar but i am getting an error "response is not available in this context"
on Response.ContentType = "text/x-vcalendar" .
I am using vb.net , 1.1 framework.
Any ideas?

If your code is wrapped up in a class you may not be able to access the Response. You could try using HttpContext.Current.Response.ContentType.
