how to get the whole inside dict in nested dict in python?

Question

I have json rpc dict:

{jsonrpc: "2.0", method: "secret", params: {book: {book_dict}}, "id": 1}

this is what I submit it by ajax:

$.ajax({
    url: "RPC2",
    type:'post',
    dataType:'json',
    data : {jsonrpc: "2.0", method: "secret", params: {book: {book_dict}}, "id": 1},
    success: function( data ) {
    console.info(data)
    $( "#temp" ).html( "<strong>" + data + "</strong> degrees" );
    }
    });

the received part by below code:

re=request.REQUEST
for k in re:
    print "dict[%s] =" % k,re[k]

the received part is:

dict[id] = 1
dict[jsonrpc] = 2.0
dict[method] = secret
dict[[title]] = my writing
dict[params[author]] = me
...

I want to get the params objects:

rep = re.get('params', None)
print rep

Here I want get the objects (books), but here it just return me with None. How to get and rebuild the object dict in nested dict?

the print repr(re):

MergeDict(<QueryDict: {u'params[book][author]': [u'me'], u'params[book
][title]': [u'my writing'], u'jsonrpc': [u'2.0'], u'method': [u'secret'], u'id':
[u'1']}>, <QueryDict: {}>)

ps: I want build the whole object book: {title: "my writing", author： "me"}, but I do not know the class name and their attributes name before. so I can only use the property to build the objects.

If you want to post JSON, encode the JSON data structure, jQuery does not do that for you:

$.ajax({
    url: "RPC2",
    type: 'post',
    dataType: 'json',
    data : JSON.stringify({jsonrpc: "2.0", method: "secret", params: {book: {book_dict}}, "id": 1}),
    success: function( data ) {
        console.info(data);
        $( "#temp" ).html( "<strong>" + data + "</strong> degrees" );
    }
});
