HTTPS POST请求Python，返回.csv [英] HTTPS POST request Python, returning .csv
问题描述
我想向HTTPS站点发出发布请求，该请求应以.csv文件作为响应.我有以下Python代码:
I want to make a post request to a HTTPS-site that should respond with a .csv file. I have this Python code:
try:
#conn = httplib.HTTPSConnection(host="www.site.com", port=443)
=>给出BadStatusLine:''错误
=> Gives an BadStatusLine: ' ' error
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">

我做错了什么?如何捕捉"返回的.csv文件? 我尝试了使用Chrome扩展程序(Advanced Rest Client，并且正在运行...)的POST请求
What am I doing wrong? How do I 'catch' the returning .csv file? I tried the POST request with an Chrome Extentions (Advanced Rest Client, and that's working...)
推荐答案
出现302错误的HTML输出是因为您正在使用HTTP而不是HTTPS连接到站点，这在您的代码中:
The HTML output with the 302 error is because you're connecting to the site using HTTP instead of HTTPS, which is in your code here:
conn = httplib.HTTPConnection("www.site.com");
大概是由于代码注释部分中的其他错误而导致的.
Presumably you're doing that because of some other error with the commented out section of your code.
如果我尝试执行此操作，则可以使用请求，该请求非常清晰地包含文档.使用Requests的代码将类似于:
If I were trying to do this I would use Requests, which comes with very clear documentation. With Requests the code would be something like:
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文件应位于r.content中，可以将其写入文件.
The CSV file should be in r.content, which can be written to a file.
