用Python发送数据Curl / Json

问题描述

我正在尝试用python发出这2个请求：

I`m trying to make those 2 requests in python:

请求1：

 curl -X POST -H "Content-Type: application/json" -d '{ "auth_token": "auth1", "widget":   "id1", "title": "Something1",  "text": "Some text", "moreinfo": "Subtitle" }'   serverip

请求2 ：

 vsphere_dict = {}
 vsphere_dict['server_name'] = "servername"
 vsphere_dict['api_version'] = apiVersion
 vsphere_dict['guest_count'] = guestCount
 vsphere_dict['guest_on']    = guestOnLen
 vsphere_dict['guest_off']   = guestOffLen

 #Convert output to Json to be sent
 data = json.dumps(vsphere_dict)

 curl -X POST -H "Content-Type: application/json" -d 'data' serverip

它们似乎都不起作用。我可以用Python发送它们吗？

Neither of them seems to work. Is there any way I can send them in Python?

更新：

我无法处理的部分是通过身份验证和小部件。我尝试了以下操作，但没有成功：

The part that I cannot handle is the pass auth and widget. I have tried the following without success:

import urllib2
import urllib

vsphere_dict = dict(
    server_name="servername",
    api_version="apiVersion",
    guest_count="guestCount",
    guest_on="guestOnLen",
    guest_off="guestOffLen",
)

url = "http://ip:port"

auth = "authid89"
widget = "widgetid1"

# create request object, set url and post data
req = urllib2.Request(auth,url, data=urllib.urlencode(vsphere_dict))
# set header
req.add_header('Content-Type', 'application/json')
# send request
response = urllib2.urlopen(req)**

导致 urllib2.HTTPError：HTTP错误500：内部服务器错误

Resulting in "urllib2.HTTPError: HTTP Error 500: Internal Server Error"

任何想法我可以正确传递身份验证和窗口小部件？

Any ideas how I can pass the auth and widget correctly?

更新：

要查看有什么不同，我已经开始了nc本地服务器。结果如下：

To see what is different I have started a nc server locally. Here are the results:

使用以下代码纠正卷曲请求：

Correct curl request using this code:

 curl -X POST -H "Content-Type: application/json" -d '{ "auth_token": "auth", "widget": "widgetid", "title": "Something", "text": "Some text", "moreinfo": "Subtitle" }' http://localhost:8123

发送确实有效：

 POST / HTTP/1.1
 User-Agent: curl/7.21.0 (i386-redhat-linux-gnu) libcurl/7.21.0 NSS/3.12.10.0 zlib/1.2.5  libidn/1.18 libssh2/1.2.4
 Host: localhst:8123
 Accept: */*
 Content-Type: application/json
 Content-Length: 165

 { "auth_token": "token", "widget": "widgetid", "title": "Something", "text": "Some text", "moreinfo": "Subtitle" }

并使用此代码请求

  import requests
  import simplejson as json

  url = "http://localhost:8123"
  data = {'auth_token': 'auth1', 'widget': 'id1', 'title': 'Something1', 'text': 'Some   text', 'moreinfo': 'Subtitle'}
  headers = {'Content-type': 'application/json'}
  r = requests.post(url, data=json.dumps(data), headers=headers)

发送此无效的文件：

 POST / HTTP/1.1
 Host: localhst:8123
 Content-Length: 108
 Content-type: application/json
 Accept-Encoding: gzip, deflate, compress
 Accept: */*
 User-Agent: python-requests/2.0.1 CPython/2.7.0 Linux/2.6.35.14-106.fc14.i686

 {"text": "Some text", "auth_token": "auth1", "moreinfo": "Subtitle", "widget": "id1",  "title": "Something1"}

推荐答案

请求为您提供了处理Python中HTTP请求的最简单但又非常（非常）强大的方法。

Requests provides you with the simplest and yet (very) powerful way to deal with HTTP requests in Python.

也许可以尝试以下方法：

Maybe try something like this:

import requests
import simplejson as json

url = "http://ip:port"
data = {'auth_token': 'auth1', 'widget': 'id1', 'title': 'Something1', 'text': 'Some text', 'moreinfo': 'Subtitle'}
headers = {'Content-type': 'application/json'}
r = requests.post(url, data=json.dumps(data), headers=headers)

如果API请求身份验证：

If the API requests authentication:

r = requests.post(url, data=json.dumps(data), headers=headers, auth=('user', 'pass'))

请参见[要求授权]以获取详细信息。

See [Requests auth] for details.
