AngularJS restmod: POST request to Django REST of string with "?a=b"

Question

I am using angular-restmodto send POST requests to a Django REST Framework backend. But whenever a string containing ? will result in a broken POST data (when received): For instance, suppose I am sending POST data

{"properties": "values", "status": "?a=3", "other properties": "other values"}

the backend will receive request.data

MergeDict(<QueryDict: {u'{"properties": "values", "status": "?a': [u'3", "other properties": "other values"']}>, <MultiValueDict: {}>)

where things starts to fall apart at =.

PUT methods works fine in these kind of cases. I wonder how to fix this?

========== EDIT ========== In the end I found an old setting for $http:

# $httpProvider.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded"

which overwrites the default JSON content type of restmod. I removed it, and the problem is solved.

While I do not know exactly how anuglar-restmod works, it looks like you are trying to send JSON-like data, but it's actually being sent as form-encoded data. When data is form-encoded, it is combined to form key1=val1[&key2=val2...] and sent as one long string in the request body.

So while you were expecting the JSON data to be sent as

{"properties": "values", "status": "?a=3", "other properties": "other values"}

It was really being sent as form-encoded data, taking the form of

{"properties": "values", "status": "?a=3", "other properties": "other values"

Which should make it somewhat obvious what your issue actually is: It's not actually being form-encoded. This is being broken up such that {"properties": "values", "status": "?a is the key and 3", "other properties": "other values" is the value.

So part of this may be the fault of the tools you are using, but there is one easy way to fix it: make sure you are using JSON.

Thank you. Indeed Chrome shows that POST data are sent in form data. Let me check how to modify it.
