Django parsing angular post data

In the process of using Django and angular, there was a problem with a angular to the Django post data.

Angular$http ({    URL: "Myviews",    Method: "POST",    data: {' text ': ' Hello World ', ' Date ': ' 2017-01-04 '}})

# djangodef Myviews (Request):    print request. POST    Print Request.body

The above will print out

<querydict: {}>u "{' text ': ' Hello World ', ' Date ': ' 2017-01-04 '}"

And we expect this to be the result

<querydict: {u ' text ': U ' Hello World ', u ' date ': U ' 2017-01-04 '}>u ' {' text ': ' Hello World ', ' Date ': ' 2017-01-04 '} '

This problem occurs because the data format that angular sends by default is JSON not urlencode , and Django request.POST cannot parse JSON it, so the results above will appear.

There are many ways to solve this, and the simplest and most brutal approach is to parse it in every view function. request.body

def myviews (Request):    data = UrlEncode (Json.loads (request.body))    Q_data = querydict (data)

We can extract this type of operation and write it Middlerware in a request uniform process before the request reaches the view function.

class jsonmiddleware (object): "" "Process Application/json requests data from G    ET and POST requests. "" "Def process_request (self, request): If ' Application/json ' in Request.            meta[' content_type ': data = Json.loads (request.body) Q_data = Querydict (", mutable=true)                        For key, value in Data.iteritems (): If Isinstance (value, List): For x in Value:  Q_data.update ({key:x}) else:q_data.update ({key:value}) if Request.method = = ' GET ': request. GET = Q_data if Request.method = = ' POST ': request. POST = q_data return None 

Because request there is no CONTENT-TYPE such request Header , we need to judge that the reason is not simply translated into Dict the QueryDict principle of consistency, we want to bind the results to request.GET or request.POST above, and they are all QueryDict types. QueryDictand Dict The biggest difference is that QueryDict each value exists in the list, and QueryDict is a non-modifiable type. So value we have to make a decision when it comes to the list, otherwise the entire list will be stored as an element QueryDict in the list.

A = {"A": [123, 456, 444], "B": 456}# do not judge data = Querydict (", mutable=true) for K, V in A.iteritems ():    data.update ({k  : v}) Print data# make judgment data = Querydict (' mutable=true) for K, V in A.iteritems ():    if Isinstance (V, list): For        x in Value:            data.update ({k:x})    else:        data.update ({k:v}) print data

<querydict: {u ' a ': [[123, 456, 444]], u ' B ': [456]}><querydict: {u ' a ': [123, 456, 444], u ' B ': [456]}>
