我想从互联网上获取信息,我使用 python mechanize 模块来做到这一点,但是它需要在请求时发布有效负载,我尝试了很多方法但仍然失败。请帮我。
这是我掌握的帖子数据:

要求

URL:xxxxxx
请求方法:POST
状态码:200 OK

请求标头

**Accept:application/json, text/javascript, */*; q=0.01**  
Accept-Charset:gb18030,utf-8;q=0.7,*;q=0.3  
Accept-Encoding:gzip,deflate,sdch  
Accept-Language:en-US,en;q=0.8,zh-CN;q=0.6,zh;q=0.4  
Connection:keep-alive  
Content-Length:52  
**Content-Type:application/json; charset=UTF-8**  
Cookie:ASP.NET_SessionId: sanntewiq5cz5uq1y0l5g3gy  
Host:xxx.xxx.xxx.xxx:8500  
Origin:xxx.xxx.xxx.xxx:8500  
User-Agent:Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.17 (KHTML, like Gecko)  Chrome/24.0.1312.57 Safari/537.17  
**X-Requested-With:XMLHttpRequest**

请求有效载荷

{dispatchorderid:"966A48E572624F2FB2E99F371C232729"}

这是我的代码:

br = mechanize.Browser()
payload = {'dispatchorderid': "966A48E572624F2FB2E99F371C232729"}
json_data = json.dumps(payload)
br.addheaders = [('Content-Type', 'application/json; charset=UTF-8'),
                ('Accept', 'application/json, text/javascript, */*; q=0.01'),
                ('X-Requested-With', 'XMLHttpRequest')]
br.set_debug_http(True)
res = br.open(url, json_data)

当我运行这个脚本时,发送信息是:

send: 'POST /DealerManage/AddDispatchorder.aspx/GetDispatchorderEntityList HTTP/1.1\r\nAccept-Encoding: identity\r\nContent-Length: 55
Connection: close
Accept: application/json, text/javascript, / ; q=0.01
主机:125.64.15.71:8500
Cookie:ASP.NET_SessionId=34dyw50d3omel2vbsvm41zwp
X-Requested-With:XMLHttpRequest
* Content-Type:application/x-www-form-urlencoded'



为什么 Content-Type 不会更改为 'application/json; 字符集=UTF-8'?

requests这个问题真的很老了,但现在使用这个包要容易得多:

import requests
head = { 'Content-Type': 'application/json; charset=UTF-8',
         'Accept': 'application/json, text/javascript, */*; q=0.01',
         'X-Requested-With': 'XMLHttpRequest' }
data = dict(dispatchorderid="966A48E572624F2FB2E99F371C232729")
response = requests.post(url, json.dumps(data), headers=head)

print response.text
