Question

在尝试使下一个代码正常工作时，我遇到了一些异常。

Python 2.7：

    jsonDictionaryInner["message"] = message_received
    jsonDictionaryInner["mac"] = repr(myMACInner)
    jsonDictionaryInner["mac"] = jsonDictionaryInner["mac"].replace('\'', '')
    try:
      json_dumped = json.dumps(jsonDictionaryInner)
      headers = {'Content-type': 'application/json', 'Authorization': myMACInner, 'Content-Length':len(json_dumped)}

      if type_message == "obs":
        requests.post(urlObservation, data=json_dumped, headers=headers)

json_dumped看起来像这样，如果我在发布之前打印它：

{"message": {"measurements": [{"position": 0, "sensor": 11, "value": 26.56}, {"position": 1, "sensor": 12, "value": 90.0}, {"position": 1, "sensor": 13, "value": 23.2}], "id": 34, "observationDate": "2016-03-03 19:39:37"}, "mac": "8b:45:ed:11:77:ab\\n"}

我伪造了mac，但它与那个相似。

在node.js方面：

app.post('/adddevice', function(req, res) {
  console.log("adddevice");
  addDevice(req.get('authorization'), req.body, function(data){
                                                    res.send(data);
                                            });
});

python方面的异常：

('Connection aborted.', BadStatusLine("''",))

在node.js方面：

SyntaxError: Unexpected end of input
at Object.parse (native)
at parse (/home/myfolder/myapi/node_modules/body-parser/lib/types/json.js:88:17)

at IncomingMessage.EventEmitter.emit (events.js:92:17)
at _stream_readable.js:920:16
at process._tickCallback (node.js:415:13)

我在node.js中使用express和body-parser，在python中使用json和request

似乎json有效负载以某种方式被截断。你可以打印节点在有效载荷中接收的内容吗？

将json从python发送到节点
