[英]python parse http response (string)
我正在使用 python 2.7,我想解析我已經從文本文件中提取的字符串 HTTP 響應字段。 什么是最簡單的方法? 我可以使用 BaseHTTPServer 解析請求,但無法找到響應的內容。
我的回答非常標准,格式如下
HTTP/1.1 200 OK
Date: Thu, Jul 3 15:27:54 2014
Content-Type: text/xml; charset="utf-8"
Connection: close
Content-Length: 626
提前致謝,
您可能會發現這很有用,請記住HTTPResponse並非旨在“由用戶直接實例化”。
另請注意,響應字符串中的內容長度標頭可能不再有效(這取決於您如何獲取這些響應)這僅意味着對 HTTPResponse.read() 的調用需要具有大於內容的值為了得到這一切。
在python 2中,它可以這樣運行。
from httplib import HTTPResponse
from StringIO import StringIO
http_response_str = """HTTP/1.1 200 OK
Date: Thu, Jul 3 15:27:54 2014
Content-Type: text/xml; charset="utf-8"
Connection: close
Content-Length: 626"""
class FakeSocket():
def __init__(self, response_str):
self._file = StringIO(response_str)
def makefile(self, *args, **kwargs):
return self._file
source = FakeSocket(http_response_str)
response = HTTPResponse(source)
response.begin()
print "status:", response.status
print "single header:", response.getheader('Content-Type')
print "content:", response.read(len(http_response_str)) # the len here will give a 'big enough' value to read the whole content
在python 3中, HTTPResponse
是從http.client
導入的,需要解析的響應需要進行字節編碼。 取決於從中獲取數據的位置,這可能已經完成或需要顯式調用
from http.client import HTTPResponse
from io import BytesIO
http_response_str = """HTTP/1.1 200 OK
Date: Thu, Jul 3 15:27:54 2014
Content-Type: text/xml; charset="utf-8"
Connection: close
Content-Length: 626
teststring"""
http_response_bytes = http_response_str.encode()
class FakeSocket():
def __init__(self, response_bytes):
self._file = BytesIO(response_bytes)
def makefile(self, *args, **kwargs):
return self._file
source = FakeSocket(http_response_bytes)
response = HTTPResponse(source)
response.begin()
print( "status:", response.status)
# status: 200
print( "single header:", response.getheader('Content-Type'))
# single header: text/xml; charset="utf-8"
print( "content:", response.read(len(http_response_str)))
# content: b'teststring'
您可能需要考慮使用 python-requests。

這是來自http://dancallahan.info/journal/python-requests/的示例
考慮到您的響應符合 HTTP RFC
這看起來像你想做的事情嗎?
>>> import requests
>>> url = 'http://example.test/'
>>> response = requests.get(url)
>>> response.status_code
200
>>> response.headers['content-type']
'text/html; charset=utf-8'
>>> response.content
u'Hello, world!'
