HTTPS POST请求Python,返回.csv

标签: python post https urllib httplib

我想向应该使用.csv文件回复的HTTPS站点发送帖子请求。我有这个Python代码:

try:
    #conn = httplib.HTTPSConnection(host="www.site.com", port=443)

=>给出BadStatusLine:''错误

    conn = httplib.HTTPConnection("www.site.com");
    params  = urllib.urlencode({'val1':'123','val2':'abc','val3':'1b3'})
    conn.request("POST", "/nps/servlet/exportdatadownload", params)
    content = conn.getresponse()
    print content.reason, content.status
    print content.read()
    conn.close()
except:
    import sys
    print sys.exc_info()[:2]

输出:

Found 302

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<TITLE>302 Found</TITLE>

我做错了什么?我如何“捕获”返回的.csv文件? 我尝试使用Chrome Extentions(高级休息客户端,并且正在运行......)

的POST请求

带有302错误的HTML输出是因为您使用HTTP而不是HTTPS连接到网站,这位于您的代码中:

conn = httplib.HTTPConnection("www.site.com");

可能是因为您的代码中已注释掉的部分出现了其他错误,所以您正在这样做。

如果我尝试这样做,我会使用Requests,其中非常明确documentation。使用请求代码将类似于:

import requests

url = "https://www.example.com/nps/servlet/exportdatadownload"
payload = { "val1": "123", "val2": "abc", "val3": "1b3" }
r = requests.post(url, data=payload, verify=True)

CSV文件应该在r.content中,可以写入文件。
