python - 使用 Python 发出 POST 请求

Question

我正在尝试发出 POST 请求但收到此错误:

Traceback (most recent call last):
  File "demo.py", line 7, in <module>
    r = requests.post(url, data=payload, headers=headers)
  File "/usr/local/lib/python2.7/dist-packages/requests/api.py", line 87, in post
    return request('post', url, data=data, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/api.py", line 44, in request
    return session.request(method=method, url=url, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 266, in request
    prep = req.prepare()
  File "/usr/local/lib/python2.7/dist-packages/requests/models.py", line 215, in prepare
    p.prepare_body(self.data, self.files)
  File "/usr/local/lib/python2.7/dist-packages/requests/models.py", line 338, in prepare_body
    body = self._encode_params(data)
  File "/usr/local/lib/python2.7/dist-packages/requests/models.py", line 74, in _encode_params
    for k, vs in to_key_val_list(data):
ValueError: too many values to unpack

这是我的程序:

import requests

url = 'http://www.n-gal.com/index.php?route=openstock/openstock/optionStatus'

payload = {'var:1945,product_id:1126'}
headers = {'content-type': 'application/x-www-form-urlencoded'}
r = requests.post(url, data=payload, headers=headers)

我已经使用以下数据通过 Advanced rest 客户端尝试了相同的 POST 请求:

网址:http://www.n-gal.com/index.php?route=openstock/openstock/optionStatus有效负载:var=1945&product_id=1126内容类型:application/x-www-form-urlencoded

它工作正常，有人能帮帮我吗...

Answer 1

您已将payload设为set ，不是字典。你忘了关闭字符串。

改变:

payload = {'var:1945,product_id:1126'}

收件人:

payload = {'var':'1945','product_id':'1126'}

因为是集合，所以请求会失败。
