响应Python中检索JSON为POST(Retrieving JSON in Python in

我试图从服务器获取JSON在Python代码中使用它。出于测试目的，我做了POST通过curl ：

$ curl -u trial:trial -H "Content-Type: application/json"
-X POST -d '{"BP_TSM":"22"}' http://some-host --trace-ascii -

我的Java代码似乎正确处理创建JSON作为响应。请看看结果curl命令：

 == Info: About to connect() to localhost port 8080 (#0)
== Info:   Trying ::1...
== Info: Connected to localhost (::1) port 8080 (#0)
== Info: Server auth using Basic with user 'trial'
=> Send header, 224 bytes (0xe0)

{"title":"Free Music Archive - Albums","message":"","total":"11259","total_pages

":2252,"page":1,"limit":"5"}== Info: Connection #0 to host localhost left intact

现在我想Python脚本能够收到同一消息curl一样。我写了下面的Python代码（注意我不是Python开发）：

import pickle
import requests
import codecs
import json
from requests.auth import HTTPBasicAuth
from random import randint
req = requests.get('server/get/auth', auth=HTTPBasicAuth('trial', 'trial'))
return pickle.dumps(req)

不幸的是，我遇到错误信息'unicode' object has no attribute 'copy'的时候return pickle.dumps(req)执行命令。我使用也尝试return json.dumps(req)但这个时候，我得到另一个错误：

Traceback (most recent call last):
  File "/tmp/tmp8DfLJ7/usercode.py", line 16, in the_function
    return json.dumps(req)
  File "/usr/lib64/python2.7/json/__init__.py", line 244, in dumps
    return _default_encoder.encode(obj)
  File "/usr/lib64/python2.7/json/encoder.py", line 207, in encode
    chunks = self.iterencode(o, _one_shot=True)
  File "/usr/lib64/python2.7/json/encoder.py", line 270, in iterencode
    return _iterencode(o, 0)
  File "/usr/lib64/python2.7/json/encoder.py", line 184, in default
    raise TypeError(repr(o) + " is not JSON serializable")
TypeError: <Response [405]> is not JSON serializable

我有一些错误在Python代码或它的故障我的Java服务器返回不正确JSON的？

Answer 1:

有一些在你的Python代码错误。

您正在使用request.get为POST。相反，使用request.post 。
你是不是传递BP_TSM JSON字符串到您的要求。使用data=在request.post 。
你是不是仿效-H开关卷曲。使用headers=你request.post 。
您正在使用pickle没有明显的原因。不要那样做。
您使用的是return的时候你是不是在函数语句。不要那样做。如果你要打印到标准输出，使用print()或sys.stdout.write()来代替。
如果你真的想使用从JSON返回的变量（而不是简单地打印到标准输出），您768,16调用req.json()

这是解决问题的一个版本的代码。

import requests
import json
import sys
from requests.auth import HTTPBasicAuth

data = '{"BP_TSM": "22"}'                       # curl -d
headers = {'content-type': 'application/json'}  # curl -H
auth = HTTPBasicAuth('trial', 'trial')          # curl -u

req = requests.post(                            # curl -X POST
    'http://httpbin.org/post',
    auth=auth,
    data=data,
    headers=headers)
sys.stdout.write(req.text)         # Display JSON on stdout
returned_data = req.json()
my_ip = returned_data["origin"]    # Query value from JSON
print("My public IP is", my_ip)

Answer 2:

你试图转储Response对象。

请返回req.json()或致电json.loads(req.text)

Answer 3:

为了加载JSON字符串，你需要使用json.loads(req.text)

此外，还必须确保REQ字符串是有效的JSON。

例如

'{"FOO":"BAR"}'

Answer 4:

您可以使用requests.json()方法获得尽可能字典JSON响应

req = requests.get('http://yourdomain.com/your/path', auth=HTTPBasicAuth('trial', 'trial'))
mydict = req.json()
