request.POST is just a dictionary-like object, so just index into it with dict syntax.

Assuming your form field is fred, you could do something like this:

<pre><code>if 'fred' in request.POST:
 mydata = request.POST['fred']
</code></pre>

Alternately, use a form object to deal with the POST data.

blocks|key|1275296|text|HTTP+POST有效负载只是一堆扁平的字节。Django+(像大多数框架一样)通过URL编码参数或MIME多部分编码将其解码到字典中。如果只是将JSON数据转储到POST内容中，Django不会对其进行解码。从完整的POST内容(而不是字典)进行JSON解码；或者将JSON数据放入MIME多部分包装器中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1275297|简而言之，显示JavaScript代码。问题似乎就在那里。|1275298|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

The HTTP POST payload is just a flat bunch of bytes. Django (like most frameworks) decodes it into a dictionary from either URL encoded parameters, or MIME-multipart encoding. If you just dump the JSON data in the POST content, Django won't decode it. Either do the JSON decoding from the full POST content (not the dictionary); or put the JSON data into a MIME-multipart wrapper.

In short, show the JavaScript code. The problem seems to be there.

If you are posting JSON to Django, I think you want <code>request.body</code> (<code>request.raw_post_data</code> on Django &lt; 1.4). This will give you the raw JSON data sent via the post. From there you can process it further.

Here is an example using JavaScript, <a href="http://en.wikipedia.org/wiki/JQuery" rel="noreferrer">jQuery</a>, jquery-json and Django.

JavaScript:

<pre><code>var myEvent = {id: calEvent.id, start: calEvent.start, end: calEvent.end,
 allDay: calEvent.allDay };
$.ajax({
 url: '/event/save-json/',
 type: 'POST',
 contentType: 'application/json; charset=utf-8',
 data: $.toJSON(myEvent),
 dataType: 'text',
 success: function(result) {
 alert(result.Result);
 }
});
</code></pre>

Django:

<pre><code>def save_events_json(request):
 if request.is_ajax():
 if request.method == 'POST':
 print 'Raw Data: "%s"' % request.body 
 return HttpResponse("OK")
</code></pre>

Django &lt; 1.4:

<pre><code> def save_events_json(request):
 if request.is_ajax():
 if request.method == 'POST':
 print 'Raw Data: "%s"' % request.raw_post_data
 return HttpResponse("OK")
</code></pre>

blocks|key|1275410|text|我也有同样的问题。我发布了一个复杂的JSON响应，并且我无法使用request.POST字典读取我的数据。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1275411|我的JSON帖子数据是：|1275412|//JavaScript+code:

I had the same problem. I had been posting a complex JSON response, and I couldn't read my data using the request.POST dictionary.

My JSON POST data was:

<pre><code>//JavaScript code:
//Requires json2.js and jQuery.
var response = {data:[{"a":1, "b":2},{"a":2, "b":2}]}
json_response = JSON.stringify(response); // proper serialization method, read 
 // http://ejohn.org/blog/ecmascript-5-strict-mode-json-and-more/
$.post('url',json_response);
</code></pre>

In this case you need to use method provided by aurealus. Read the request.body and deserialize it with the json stdlib.

<pre><code>#Django code:
import json
def save_data(request):
 if request.method == 'POST':
 json_data = json.loads(request.body) # request.raw_post_data w/ Django &lt; 1.4
 try:
 data = json_data['data']
 except KeyError:
 HttpResponseServerError("Malformed data!")
 HttpResponse("Got json data")
</code></pre>

I'm trying to process incoming JSON/Ajax requests with Django/Python.

<a href="https://docs.djangoproject.com/en/stable/ref/request-response/#django.http.HttpRequest.is_ajax" rel="noreferrer"><code>request.is_ajax()</code></a> is <code>True</code> on the request, but I have no idea where the payload is with the JSON data.

<code>request.POST.dir</code> contains this:

<pre><code>['__class__', '__cmp__', '__contains__', '__copy__', '__deepcopy__', '__delattr__',
 '__delitem__', '__dict__', '__doc__', '__eq__', '__ge__', '__getattribute__',

There are apparently no keys in the request post keys.

When I look at the POST in <a href="http://en.wikipedia.org/wiki/Firebug" rel="noreferrer">Firebug</a>, there is JSON data being sent up in the request.

Where's my JSON data in my incoming Django request?
