I'm getting a 404 Not Found when making this call:
var url = rootWebApiUrl + '/folders/' + $scope.selectedServer.Name + "/" + serviceName;
$http.get(url) // the rest of this line doesn't matter for this issue
I thought that maybe using encodeURIComponent would help, but I get the same 404 Not Found error:
var url = rootWebApiUrl + '/folders/' + $scope.selectedServer.Name + "/" + encodeURIComponent(serviceName);
This is the Web API Method Signature:
[Route("folders/{serverName}/{serviceName}")]
[HttpGet]
public IEnumerable<Folder> Folders(string serverName, string serviceName)
The first option (above) works if I change the service name while debugging. The original service name is Company Name Message Bus Manager 3.6 - MesFinishingEvents. If I change it to something with no spaces, like snuh, then the Web API call succeeds and I can debug in the Web API method.
How can I pass the original service name in my $http.get(url) call?
Edit: URL values:
With service name that has spaces:
http://localhost:4153/api/services/folders/ServerName/Company%20Name%20Message%20Bus%20Manager%203.6%20-%20MesFinishingEvents
Using a simple service name:
http://localhost:4153/api/services/folders/ServerName/snuh
WebAPI controllers struggle when you have a . in your parameters, here and here.
Your method call would work all the way up to:
http://localhost:4153/api/services/folders/ServerName/Company%20Name%20Message%20Bus%20Manager%203
and beyond, if the period didn't exist.
The quickest solution is to add a trailing slash. The longer solution would be to modify your sites HTTP handlers in IIS.

This is a simple to understand question, I will explain step by step as to make everything clear.
I am using the Google Feed API to load an RSS file into my JavaScript application.
I have a setting to bypass the Google cache, if needed, and I do this by appending a random number at the end of the RSS file link that I send to the Google Feed API.
For example, let's say this is a link to an RSS:
http://example.com/feed.xml
To bypass the cache, I append a random number at the end as a parameter:
http://example.com/feed.xml?0.12345
The whole url to the Google Feed API would look like this, where "q" is the above link:
https://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=5&q=http://example.com/feed.xml?0.12345
This bypasses the cache and works well in most cases but there is a problem when the RSS link that I want to use already has parameters. For example, like this:
http://example.com/feed?type=rss
Appending the number at the end like before would give an error and the RSS file would not be returned:
http://example.com/feed?type=rss?0.12345 // ERROR
I have tried using "&" to attach the random number, as so:
http://example.com/feed?type=rss&0.12345
This no longer gives an error and the RSS file is correctly returned. But if I use the above in the Google Feed API url, it no longer bypasses the cache:
https://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=5&q=http://example.com/feed.xml&0.1234
This is because "0.1234" is considered a parameter of the whole url and not a parameter of the "q" url. Therefore "q" remains only as "http://example.com/feed.xml", it is not unique so the cached version is loaded.
Is there a way to make the number parameter be a part of the "q" url and not a part of the whole url?
You need to use encodeURIComponent like this:
var url = 'http://example.com/feed.xml&0.1234';
document.getElementById('results').innerHTML = 'https://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=5&q=' + encodeURIComponent(url);
<pre id="results"></pre>
You are escaping the special characters that would have been treated as part of the url otherwise.
To append or create a queryString:
var url = 'http://example.com/feed.xml';
var randomParameter = '0.1234';
var queryString = url.indexOf('?') > - 1;
if(queryString){
url = url + '&' + randomParameter;
} else {
url = url + '?' + randomParameter;
}
//url needs to be escaped with encodeURIComponent;
You need to use encodeURIComponent to do this.
encodeURIComponent('http://example.com/feed.xml&0.1234')
will result in
http%3A%2F%2Fexample.com%2Ffeed.xml%260.1234
and when appended to the end result you'll get
https://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=5&q=http%3A%2F%2Fexample.com%2Ffeed.xml%260.1234
I am trying to parse a sequence of html pages using python, I am having trouble grabbing the pages in iterative fashion. The link to the web page.
Milano Library
After peeking through the source, I found a function that responds to the click event on button element for the next page.
function SaltaAPagina() {
var CalcPag = VAIAPAGINA.value;
if (CalcPag > 0) {
CalcPag=CalcPag;
}
else {
CalcPag="1";
}
document.location = "/OPACMI01/cat/SDW?W=CODICE_BIBLIO+%3D+%27LO1+01%27+AND+EDITORE+PH+WORDS+%27sonzogno%27+AND+DATA_PUBBLICAZIONE+%3C+1943+ORDER+BY+ORDINAMENTO/Ascend&M=" + CalcPag + "&R=Y";
}
I know that I can encode parameters using pythons urllib2 module using the urlencode method. But I am not sure what I should be including as a parameter
lomba_link='http://www.biblioteche.regione.lombardia.it/OPACMI01/cat/SDW?W%3DCODICE_BIBLIO+%3D+%27LO1+01%27+AND+EDITORE+PH+WORDS+%27sonzogno%27+AND+DATA_PUBBLICAZIONE+%3C+1943+ORDER+BY+ORDINAMENTO/Ascend%26M%3D1%26R%3DY'
params = urllib.urlencode([('CalcPag',4)])
# this has not worked.
req = urllib2.Request(lomba_link)
print req
response = urllib2.urlopen(req,params)
html_doc = response.read()
What am I missing here?
Thanks
The javascript function you posted is passing several parameters to the target page:
document.location = "/OPACMI01/cat/SDW" + // This is the path of the page
"?W=CODICE_BIBLIO+%3D+%27LO1+01%27+AND+EDITORE+PH+WORDS+%27sonzogno%27+AND+DATA_PUBBLICAZIONE+%3C+1943+ORDER+BY+ORDINAMENTO/Ascend" + // The first parameter
"&M=" + CalcPag + // The second parameter
"&R=Y"; // The third parameter
In your code, you've encoded all of the & and = symbols in the URL, so you're passing a single, long parameter with no value - changing those symbols back to what they were in the javascript function should do the trick.
lomba_link='http://www.biblioteche.regione.lombardia.it/OPACMI01/cat/SDW'
params = urllib.urlencode([
('W', 'CODICE_BIBLIO+%3D+%27LO1+01%27+AND+EDITORE+PH+WORDS+%27sonzogno%27+AND+DATA_PUBBLICAZIONE+%3C+1943+ORDER+BY+ORDINAMENTO/Ascend'),
('M', 4),
('R', 'Y')
])
It's much easier to work with the brilliant requests library, rather than the urllib2 library...
In regards to urllib2.urlopen the params is for POST requests. Unfortunately you need to append the query string to the url to make a GET request.
eg:
req = urllib2.urlopen(req + '?' + params)
With requests, this would be much simpler:
page = requests.get(some_url, params={'CalcPag': '4'})
Quick background -
I am making a jQuery ajax call to a service I wrote that returns a JSON response. The service accepts a web site URL (i.e. www.google.com, www.xyz.com/abc123). The format of the request is as follows:
http://www.mysite.com/[url]
... where [url] is a user provided URL (again, something like www.google.com/abc)
I need to URL encode the parameter, as mysite.com/www.google.com is giving me errors.
My problem is, all of the standard javascript encoding functionality does not actually encode the URL.
An example:
<html>
<head>
<script>
document.write("encodeURIComponent = " + encodeURIComponent("www.google.com") + "<br />");
document.write("encodeURI = " + encodeURI("www.google.com") + "<br />");
document.write("escape = " + escape("www.google.com"));
</script>
</head>
<body>
</body>
... has the following output:
encodeURIComponent = www.google.com
encodeURI = www.google.com
escape = www.google.com
What is the proper way to achieve this using JavaScript/jQuery?
I don't think it's relevant, but just in case, this is a Rails 3.0.7 app.
EDIT FOR MORE DETAIL
If www.google.com is already URL encoded, and periods are fine in my URL (www.mysite.com/www.google.com), why am I getting this error?
From Chrome Dev Tools:
GET http://localhost:3000/s/www.google.com 404 (Not Found)
My jQuery snippet:
$.getJSON("http://localhost:3000/s/" + encodeURI($("#txtURL").val()), function(data) {
alert(data.result.url);
});
This is a perfectly valid URL:
http://mysite.com/s/www.google.com
I suspect that you're just running into the Rails format stuff (i.e. .html at the end of the URL sets the format to HTML, .js for JSON, ...) so you just need to fix your route to keep the format auto-detection from getting in the way:
map.connect '/s/:url', :requirements => { :url => /.*/ }, ...
or
match '/s/:url' => 'pancakes#house', :constraints => { :url => /.*/ }, ...
or whatever routing syntax you're using.
If you don't tell rails that the :url should match /.*/ (i.e. anything at all), it will try to interpret the periods in the route as format specifiers, that will fail and Rails will 404 because it can't figure out how to route the URL.
URL encoding escapes characters that have a special meaning in the URL (like / and ?) and/or aren't ASCII characters. http://mysite.com/www.google.com is a perfectly valid URL, there's nothing to escape. If you'd include the protocol as well, you'd get some escape-worthy characters:
encodeURIComponent('http://www.google.com')
"http%3A%2F%2Fwww.google.com"
If your server 404s on a request to http://localhost:3000/s/www.google.com, that means the URL isn't handled by the server. It doesn't mean that the URL is invalid.
As mu said dots don't need to be encoded.
The jQuery-way for building a proper QUERY_STRING would be the use of $.param()
$.param({encodeURIComponent:'http://www.google.de'})
I have an action that takes 2 strings. One of the strings is a big, ugly json string. I suspect that the action will not allow the special characters to be passed because I keep getting a 400 - Bad Request.
Can a serialized json object be passed to an action?
public ActionResult SaveState(string file, string state)
{
string filePath = GetDpFilePath(file);
HtmlDocument htmlDocument = new HtmlDocument();
htmlDocument.Load(filePath);
HtmlNode stateScriptNode =
htmlDocument.DocumentNode.SelectSingleNode("/html/head/script[#id ='applicationState']");
stateScriptNode.InnerHtml = "var applicationStateJSON =" + state;
htmlDocument.Save(filePath);
return null;
}
ClientScript
'e' is a large json string
$.post('/State/SaveState/' + fileName+'/' + '/' + e + '/');
strong text
I am now encoding the text using UriEncoding() but it makes no difference. I don't think that MVC Actions allow me to send these special characters by default.. is that true? How do you work around this?
$.post('/State/SaveState/' + encodeURIComponent(fileName) + '/' + '/' + encodeURIComponent(e) + '/');
Sample request:
Request URL:http://localhost:51825/State/SaveState/aa6282.html//%7B%22uid%22%3A%22testUser%22%2C%22a
You need to encode it when the request is made:
$.post('/State/SaveState/' + encodeURIComponent(fileName) + '/' + encodeURIComponent(e));
Yes, serialized JSON object can be passed to an action method. MVC3 makes this even easier with built-in JSON binding. I use the json2 library to serialize the objects. See this post for more details. Works really great.

Because I am send this data to the sever and the size of the string I am sending is large. I really should be sending the data in the post body.
It seems that there is also a limitation on the amount of data that you can send via the query string. I cannot be certain that this was the source of the error message but it certainly would make sense. In case the following post works correctly:
$.post('/State/SaveState/', { file: fileName, state: e });
You probably need to HTML-encode e before you add it to the URL. Also, you have an extra / that you don't need.
$.getJSON(
main_url + "tasks/",
{ "task":8, "last":lastMsgID }
I don't really know how this works, but I need a URL or something that can get me messages from a shoutbox and this is what the function uses by default. Does it use a URL and if so how do I plug in the "task" and "last" to the URL? Or is it some other method?
I'm also not sure i fully understand what you want, but a quick explanation of what's going on there. If you check out the api for getJson you'll see that the first parameter is the url to query from and the 2nd is optional data to send to the server. So in your case, the url would be main_url + "tasks/" the data sent to the server is { "task":8, "last":lastMsgID }
If your main_url is something like www.domain.com then your whole request will look like this:
http://www.domain.com/tasks?task=8&last=xxx
where xxx is the lastMsgID
