I'm using the facebook open graph api to post to a facebook fan page. More info on the method can be found in the answer here.
When one manually posts on facebook they can use # to link a particular person e.g. #Michael Jackson. This auto populates a link to that persons page and shows up on their timeline. The # itself dissapears once the post has been made, leaving only the hyperlinked text i.e. Michael Jackson.
Programatically compiling a post via the api, including the #, results in the text being posted in plain text. i.e. #Michael Jackson shows as #Michael Jackson.
How can I escape, or otherwise parse the anchor through the api so that Facebook recognises it as a link to another user/page?
Edit: I found this reference which describes these links as Actions, specifically in this case a 'Mentioning friends' action. It goes on to explain the syntax of #[USERID] or #[USERNAME] which is promising. But if I compile this encoded it posts the plain encoded text e.g. %40%5BUSERID%5D, when left un-encoded the post fails.
I've found that starting your message with a mention tag (i.e. #[12345678:User Name] ) throws a CurlException error.
To fix this I changed:
'message' => '#[1234567890:User Name]';
To
'message' => ' #[1234567890:User Name]';
Simply adding a space before the mention seems to fix that problem.

Using Diagrams.net (draw.io), I would like to link specific elements to web pages. This is easily accomplished currently by creating a link for the element (say a rectangle).
However, I would like to navigate directly to a specific id bookmark in the HTML page. I cannot seem to get that to work.
For example, if I try to use this syntax (which works in the browser location bar):
https://en.wikipedia.org/wiki/Canada#Geography
I will be taken to the main page:
https://en.wikipedia.org/wiki/Canada
However, the goal is to go to the "Geography" section of this page.
I have also tried the json syntax without any success:
data:action/json,{"actions":[{"open":"https://en.wikipedia.org/wiki/Canada#Geography"}]}
I have also played with different action syntax such as:
data:action/json,{"actions":[{"open":"https://en.wikipedia.org/wiki/Canada"},{"scroll":{"tags":["Geography"]}}]}
Note: I'm using the diagrams.net desktop version 14.1.8.
Thank you for taking the time to read this question.

On Windows this only seems to work if the browser isn't already open. There is not much we can do to fix this as we're passing the link to the OS.
I'm creating a classifieds website in Django. A single view function handles global listings, city-wise listings, barter-only global listings and barter-only city-wise listings. This view is called ads.
The url patterns are written in the following order (note that each has a unique name although it's tied to the same ads view):
urlpatterns = patterns('',
url(r'^buy_and_sell/$', ads,name='classified_listing'),
url(r'^buy_and_sell/barter/$', ads,name='barter_classified_listing'),
url(r'^buy_and_sell/barter/(?P<city>[\w.#+-]+)/$', ads,name='city_barter_classified_listing'),
url(r'^buy_and_sell/(?P<city>[\w.#+-]+)/$', ads,name='city_classified_listing'),
)
The problem is that when I hit the url named classified_listing in the list above, the function ads gets called twice. I.e. here's what I see in my terminal:
[14/Jul/2017 14:31:08] "GET /buy_and_sell/ HTTP/1.1" 200 53758
[14/Jul/2017 14:31:08] "GET /buy_and_sell/None/ HTTP/1.1" 200 32882
This means double the processing. I thought urls.py returns the first url pattern matched. What am I doing wrong and what's the best way to fix this? All other calls work as expected btw (i.e. only once).
Note: Ask for more information in case I've missed something.
Great explanation to understand these type of occurences: https://groups.google.com/d/msg/django-users/CRMMYWix_60/KEIkguUcqxYJ
This issue has nothing to do with how url patterns are ordered in urls.py.
Like pointed out in the comments under the question, this has to do with problematic asset references in the HTML template.
What does that mean?
For instance, try curl -i http://localhost:8000/example/ >> output.txt in your terminal. Then open up output.txt in your editor of choice. Now search for href or src attributes where values are None (or otherwise malformed). That's one reason a double call is being created. That was the reason for me. I removed these, and the double call disappeared.
There's this old - but relevant - writeup about how to comprehensively diagnose this problem on your machine here: https://groups.google.com/forum/#!msg/django-users/CRMMYWix_60/KEIkguUcqxYJ
Happy testing.
As I can't comment on other answers, just to add for future wanderers that for me the "problem" was in a correctly formed but yet for the browser instructing <iframe src="#"..> tag. On django server the view was rendering twice, once with original request and then again by the hidden iframe element that I used for some of the modal popups later in the page usage.
After emptying the src attribute like <iframe src=""..> a second request is no longer initiated and my modals work fine.
The solution actually is from the link posted already in answers before [https://groups.google.com/forum/#!msg/django-users/CRMMYWix_60/KEIkguUcqxYJ][1]
where it is explained:
Note that it's a URI. That means something that is retrieved. Since
you've used the value "#fff", that will be interpreted by the browser as
a reference to the current page (#fff being an anchor, and not passed to
the server). Ergo, a second request is made.
that the iframe src # (anchor) is instructing the browser to load again the same URL, for the iframe element in my case.
I indeed had several style elements with #fff colors inside and whatnot, but this wasn't it, as browsers are smart enough to recognize this is not an anchor.
With available tools (browser only) I found to be easy to debug and find these initiation href/src attributes over the Network tab of your browser developer tools - in Chrome is just by clicking the Initiator link of the corresponding row - giving you the exact line from the page source that initiated the request to the same URL.
I struggled with the same problem and just wanted to share my experience with it. I had double requests all over my application but everything seemed to work as expected apart form it.
What Daniel Rossman pointet out in the comments was actually also true for my problem. I had a <link rel="shortcut icon" href="#"> in my base template which caused the double request, because of the #, which is a reference to the page itself. Once i removed it, i had no double requests anymore.
Hope this answer can save someone some debugging time.
I got double request in view function, in my scenario, this went wrong:
<img id="profile-img" src="#" alt="" class="profile-cover">
by setting src="" dismiss double request. it was a silly thing, I just thought it apply to a then must apply to img, but img actually send another request.
This could be a stupid questions for some. But its truly important for me.
I know how to switch frames using selenium webdriver.
However, is there a way to download all the page_source of the entire page for all the frames at once.
Instead of switching them again and again?
Could someone please let me know the command if it exists?
If not then please say there is none. And that should answer my question.
Thanks in advance
Webdrivers' getPageSource will return some state in some formatting of the last page the driver was on.
From the (java)docs, but most probably applies to other languages:
getPageSource
java.lang.String getPageSource()
Get the source of the last loaded page. If the page has been modified
after loading (for example, by Javascript) there is no guarantee that
the returned text is that of the modified page. Please consult the
documentation of the particular driver being used to determine whether
the returned text reflects the current state of the page or the text
last sent by the web server. The page source returned is a
representation of the underlying DOM: do not expect it to be formatted
or escaped in the same way as the response sent from the web server.
Think of it as an artist's impression.
Returns:
The source of the current page

How do I fetch Page Name with Yahoo Pipes?
I'm making a news / blog aggregator, and need to know the name of the site where the info is coming from (bbc, cnn, fox, etc).
Do I need to do this with REGEX?
Anyone that can help?
You can fetch the page using the XPath Fetch Page or Fetch Feed modules in the Sources menu. Maybe with others too.
After that you can extract the page name itself using the various operators, possibly Regex, or others, depending on the source page you are using and the output you want to get.
In general your question is too broad and difficult to answer. To get you started, I created an example pipe that extracts the title of your question from this post, which is basically the "page name" of the current page.
http://pipes.yahoo.com/pipes/pipe.info?_id=668acf3f807c30d7b75f12459edd3252
I used the XPath Fetch Page with parameters:
URL = this page
Extract using XPath = //div[#id="question-header"]
I got that div path by inspecting the source code of this page, where I saw that div#question-header is the container of a question. I could have selected a deeper inner container or a higher level container. It all depends on the amount of other information you need. The more information you want to you from the page, the higher level container you select.
Next, I used the Create RSS operator to create a proper RSS feed, with parameters:
Title = h1.a
Link = h1.a.href
I chose these elements because in the container I extracted with xpath, the page name is inside h1 a. In Yahoo Pipes you use a dot as the path separator.
I found this sample pipe http://pipes.yahoo.com/pipes/pipe.info?_id=69b5dce1c59501a0c64a660c1cfdb856. The page title included the name of the site too. I am not sure if this what you are looking for.
Situation: I am trying to call the LinkedIn API from a ColdFusion CFC to get the user's profile and network (connections). The LinkedIn API states that to do this you must call a URL with scope=r_fullprofile+r_network.
Issue: ColdFusion is automatically encoding the URL, so the plus sign is getting encoded, and LinkedIn is rejecting my call. Is there any way around this? I've posted a link below to some code snippets on github which I believe illustrate the issue.
https://gist.github.com/4535364
Any help would be appreciated!
I have searched around on this for a bit and I am seeing lots of examples where ColdFusion is not playing nicely with the LinkedIn API. So I'm afraid if you do get passed this issue (although I have not come up with an alternative yet) another will crop up. While searching I found several suggestions from people to use the linkedin-j, A Java wrapper for LinkedIn APIs instead. Here are some of the references that I found:
Working example Coldfusion and Linkedin API
LinkedIn-J does not return educations
401 Unauthorized response. API people/~ and people/id=; ColdFusion, cfhttp
Problem updating status - 401 unauthorized - ColdFusion
linkedin-j Getting Started
Side Note Your github code example is making a cfhttp call to 'receiver.cfm' but you called the file 'cfhttp_receiver.cfm'. In this line:
<cfhttp url="http://#cgi.http_host#/sandbox/receiver.cfm?scope=#url.scope#" method="post" resolveurl="no">
The scope field is a space delimited list.
The + character is commonly used as a shortcut for space, since it's more readable than %20 (which is what space encodes to).
If using a plus character results in an encoded plus (%2B) being sent, then you are left with two other ways of putting the space into the URL:
using a literal space character, or
using an encoded space %20
Try both of those options, ideally using a network snifer (e.g. WireShark) so that you can see accurately what is being sent.
Update: As per comments below, %20 is correct, but the signature based string needs to be encoded again, so for that the % becomes %25, giving a result of %2520.
