This is the request Facebook calls back:
/facebook/promo/#access_token=162592277090170%7C2.yCch3otjrdit_rgBFS6F0A__.3600.1285369200-727781553%7CtugQmoO0bRiadumHVQrrSiPRD9Y&expires_in=7174
How can I parse the access_token from the URL? I could not find any way to get the access_token value.
Please be aware that it is not a reqular parameter.
You could use a Regex to match it out of the url. Or simply take everything as a sub-string between access_token= and the next &-character or the end of the url, which ever comes first.
I believe that it's not possible - the part after # is simply ignored. See this answer: Rails: Extracting the raw url from the request
If you're only after the access_token=... section, just use some simple string matching:
url = '/facebook/promo/#access_token=162592277090170%7C2.yCch3otjrdit_rgBFS6F0A__.3600.1285369200-727781553%7CtugQmoO0bRiadumHVQrrSiPRD9Y&expires_in=7174'
url[/#access_token=(.+)&/, 1]
=> "162592277090170%7C2.yCch3otjrdit_rgBFS6F0A__.3600.1285369200-727781553%7CtugQmoO0bRiadumHVQrrSiPRD9Y"
That looks for #access_token= and grabs everything up to &.

Suppose I am expecting a url as part of my route - maybe a callback url or similar - I might use the following route:
get '/mymodel/:url', to: 'mycontroller#docallback', url: /.*/
Now I would like to be able to go to http://www.myapp.com/mymodel/http://www.google.co.uk/ and process http://www.google.co.uk/ in mycontroller - but it is processed as http:/www.google.co.uk/ (one slash). How can I rectify this? Is the regex wrong or is there some flag I have to set?
I don't think that "http://www.myapp.com/mymodel/http://www.google.co.uk/" is a valid url.
Normally if you want to pass a url as a parameter you would call CGI.escape on it first, which would convert "http://www.google.co.uk/" to "http%3A%2F%2Fwww.google.co.uk%2F" CGI.escape will turn any string into a url-safe version of itself, basically replacing any characters which have a special function in a url, like ":/?&" and also space and some other characters which would otherwise break the formatting.
So, you would end up with a url like
"http://www.myapp.com/mymodel/http%3A%2F%2Fwww.google.co.uk%2F"
which would come through in params like
params = {:url => "http://www.google.co.uk/"}
Note how it's been unescaped here: Rails automatically* calls CGI.unescape on parameter values before putting them into the params hash.
However, this url
"http://www.myapp.com/mymodel/http%3A%2F%2Fwww.google.co.uk%2F"
looks pretty weird to me. It would be better to be more explicit and pass it through as a named parameter in the url itself, like
"http://www.myapp.com/mymodel?url=http%3A%2F%2Fwww.google.co.uk%2F"
which will require a slight change to your routes.
* I think Rails will do this but it might depend on circumstances. Try it.
...Turned out that the request was not encoded on the client side before being sent, solution was to use encodeURIComponent() on the url before sending it.
want to share text and url like that:
test http://one#two#three
so i try
https://twitter.com/intent/tweet?text=test&url=http%3A%2F%2Fone%23two%23three
and get in result only "test" without the url
when in url is only one # sigh is ok
for example
https://twitter.com/intent/tweet?text=test&url=http%3A%2F%2Fone%23two
give me
test http://one#two
how to add sec #?
This is almost certainly because it is not correct syntax to have more than one # in a URL.
What sort of URL are you sharing that needs two?
If you absolutely have to, you can cheat and URL Encode the second % into %25
https://twitter.com/intent/tweet?text=test&url=http%3A%2F%2Fone%23two%2523two
How do I pass array of parameters through Get method in rails? Currently my URL loocs like this:
http://localhost:3000/jobs/1017/editing_job_suites/1017/editing_member_jobs/new?ids[]=1025&ids[]=1027
How can I pass the array with Get method but avoid ?ids[]=1025&ids[]=1027 part.
Request is being sent with javascript window.open method. Is there any workaround to send not ajax Post request.
You should stick to using a GET request if you are not changing the state of anything, and all you want to to access a read only value.
To send an array of ids to rails in a GET request simply name your variable with square brackets at the end.
//angular snippet
$http.(method:'GET',
...
params: {'channel_id':2, 'product_ids[]': productIds}
//where productIds is an array of integers
...
)
Do not concatenate your ids as a comma separated list, just pass them individually redundantly. So in the url it would look something like this:
?channel_id=2&product_ids[]=6900&product_ids[]=6901
url encoded it will actually be more like this:
?channel_id=2&product_ids%5B%5D=6900&product_ids%5B%5D=6901
Rails will separate this back out for you.
Parameters: {"channel_id"=>"2", "product_ids"=>["6900", "6901"]}
No, GET can only put variables on the url itself. If you want the URL to be shorter, you have to POST. That's a limitation feature of HTTP, not Rails.
I recently wanted to do this and found a workaround that is a little less complex, and so has some complexity limitations but may also be easier to implement. Can't speak to security, etc.
If you pass your array values as a string with a delimiter, e.g.
http://example.com/controller?job_ids=2342,2354,25245
Then you can take the result and parse it back to what you want:
job_ids = params[:job_ids].split(',')
Then do whatever:
job_ids.each do |job_id|
job = Job.find(job_id.to_i)
end
etc
#Homan answer is valid for using an external client (e.g curl or angular). Inside Rails test cases though, you should not use []. Here's an example:
get get_test_cases_url(**path_params), params: {case_ids: ["NON-9450", "NON-12345", "NON-9361"]}
This is using new format where get_test_cases is name of route and you pass to the method all params needed to construct the URL path. Query params are a separate hash.
FYI if I use [] like case_ids[], then instead of ["NON-9450", "NON-12345", "NON-9361"] I'm getting it parsed to [["NON-9450"], ["NON-12345"], ["NON-9361"]]
I’m using Backbone.js and Rails.
In Backbone.js I use HTML5 push state to set filter parameters in a url.
When the page is reloading I want to pass these parameters to Rails.
I encoded a parameter lat:34.34+lng:45.23 using JavaScript’s encodeURIComponent. It encoded:
/users/nearby/lat:34.34+lng:45.23/
as:
/users/nearby/lat%3A34.34%2Blng%3A45.23
but this route is not found.
If I delete the points from url, it works.
How can I send parameters with a decimal point?
The . is not a character that has to be encoded. Is this causing issues server side?
See here for more details:
http://www.blooberry.com/indexdot/html/topics/urlencoding.htm
I solved my problems adding an "extra" slash to the end of the url.
In your encoded url it is missing.
Hope this helps
One manifestation of this problem is in URL pattern matching, where the Query Param is expected (i.e. matched) to be an integer. This does not match a number with a decimal point. So you get a 404 (URL not found).
I have a gwt url like this
http://127.0.0.1:8888/BiddingSystem.html?gwt.codesvr=127.0.0.1:9997#ForumMessage=918
when I am doing this
Window.Location.getParameter("ForumMessage")
I am getting null??
By the way, I not getting the point why this ?gwt.codesvr=127.0.0.1:9997 in the url!!
To get the value of the URL fragment (the part after the #) call Window.Location.getHash(). This will return all of "ForumMessage=918".
getParameter() returns query parameters, not the URL fragment.
See here for more information about the parts of a URL.
The ?gwt.codesvr= part is needed to run in Development Mode.
Look at this topic GWT URL Parameters
Here is answer
url should be http://localhost:8080/?testing=abc#pg5 instead of http://localhost:8080/#pg5?testing=abc
and delete that part (?gwt.codesvr=127.0.0.1:9997 ) and run it in web mode. I think it will solve your problem
