Question

问题：recJSON = json.loads（request.body）正在抛出异常。

def addPatient(request):
    if request.method == 'POST':
        # Convert JSON to python objects and
        # store into the DB
        print request.encoding
        #body_unicode = request.body.decode('utf-8').encode('utf-16')
        #try:
        recJSON = json.loads(request.body)
        #except ValueError:
        #  print "%s",ValueError
        print "%s",request.body

        return HttpResponse(json.dumps(request.body),content_type="application/json")

例外：

 recJSON = json.loads(request.body)
 File "/usr/local/lib/python2.7/dist-packages/simplejson/__init__.py", line 505, in loads
 return _default_decoder.decode(s)
 File "/usr/local/lib/python2.7/dist-packages/simplejson/decoder.py", line 370, in decode
  obj, end = self.raw_decode(s)
 File "/usr/local/lib/python2.7/dist-packages/simplejson/decoder.py", line 400, in raw_decode
 return self.scan_once(s, idx=_w(s, idx).end())
 File "/usr/local/lib/python2.7/dist-packages/simplejson/scanner.py", line 127, in scan_once
 return _scan_once(string, idx)
 File "/usr/local/lib/python2.7/dist-packages/simplejson/scanner.py", line 118, in _scan_once
 raise JSONDecodeError(errmsg, string, idx)
 JSONDecodeError: Expecting value: line 1 column 1 (char 0)

来自客户：

使用AFNetworking并使用以下POST发送请求：

 // Create JSON data
 NSMutableDictionary* sendID = [[NSMutableDictionary alloc] init ];
 [sendID setObject:senderID forKey:@"SenderID"];

 NSMutableDictionary* sendDispName = [[NSMutableDictionary alloc] init ];
 [sendDispName setObject:displayName forKey:@"SenderDispName"];

 NSMutableDictionary* sendMessage = [[NSMutableDictionary alloc] init ];
 [sendMessage setObject:text forKey:@"Message"];

 NSMutableDictionary* sendDate = [[NSMutableDictionary alloc] init ];
 NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[sendDate setObject:[dateFormatter stringFromDate:date] forKey:@"SendDate"];


 NSMutableArray* dataToSend = [[NSMutableArray alloc] init];
 [dataToSend addObject:sendID];
 [dataToSend addObject:sendDispName];
 [dataToSend addObject:sendMessage];
 [dataToSend addObject:sendDate];

 NSData* jSenderData = [NSJSONSerialization dataWithJSONObject:dataToSend options:NSJSONWritingPrettyPrinted error:&error];

 NSLog(@"%@", [[NSString alloc] initWithData:jSenderData encoding:NSUTF8StringEncoding]);

 [_manager.requestSerializer setValue:@"TOKEN" forHTTPHeaderField:@"X-CSRFTOKEN"];
 [_manager.requestSerializer setValue:@"application/json"   forHTTPHeaderField:@"Content-Type"];


[_manager POST:@"addPatient/" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formdata)
 { [formdata appendPartWithHeaders:nil body:jSenderData];}
       success:^(NSURLSessionDataTask *task, id responseObject)

我读到UTF-8编码与json.dumps（request.body）有问题，在Python 3.0中修复了 http://bugs.python.org/issue11489

我面临的问题是否相同？这是我的第一个使用Django和Python的项目，所以任何额外的信息都将非常受欢迎。

谢谢，

我在这里做错了两件事。

在我的代码中，我创建了作为字典发送的有效负载，我使用AFJSONRequestSerializer和后来的NSJSONSerialization来获取NSData（传递给请求结构）。换句话说，我试图创建JSON数据的JSON。

 NSData* jSenderData = [NSJSONSerialization dataWithJSONObject:dataToSend options:NSJSONWritingPrettyPrinted error:&error];

 NSLog(@"%@", [[NSString alloc] initWithData:jSenderData encoding:NSUTF8StringEncoding]);

[_manager.requestSerializer setValue:@"TOKEN" forHTTPHeaderField:@"X-CSRFTOKEN"];
[_manager.requestSerializer setValue:@"application/json"   forHTTPHeaderField:@"Content-Type"];


[_manager POST:@"addPatient/" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formdata)

{[formdata appendPartWithHeaders：nil body：jSenderData];} 成功：^（NSURLSessionDataTask * task，id responseObject）

我要做的第二件事是使用多部分表单请求。我试图将JSON数据作为多部分表单的一部分发送。这未在服务器上正确解释。

感谢社区的帮助。
