python - 将带有 json 的帖子从 python 发送到 Node

Question

我在尝试使下一个代码正常工作时遇到一些异常。

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)

如果我在发布之前打印它，json_dumped 看起来像这样:

{"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，但它与那个类似。

在node.js端:

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

Python 端出现异常:

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

在node.js端:

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 /home/myfolder/myapi/node_modules/body-parser/lib/read.js:116:18

at IncomingMessage.EventEmitter.emit (events.js:92:17)

at process._tickCallback (node.js:415:13)

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

似乎 json 负载被某种方式截断了。你能打印出 Node 在有效负载中实际接收到的内容吗？
