python parse http响应（字符串）

python parse http响应（字符串）

您可能会发现这很有用，请记住HTTPResponse并非旨在“由用户直接实例化”。

还要注意，响应字符串中的content-
length标头可能不再有效（取决于您获取这些响应的方式），这仅意味着对HTTPResponse.read（）的调用需要具有大于内容的值为了得到一切。

在python 2中，可以这种方式运行。

from httplib import HTTPResponsefrom StringIO import StringIOhttp_response_str = """HTTP/1.1 200 OKDate: Thu, Jul  3 15:27:54 2014Content-Type: text/xml; charset="utf-8"Connection: closeContent-Length: 626"""class FakeSocket():    def __init__(self, response_str):        self._file = StringIO(response_str)    def makefile(self, *args, **kwargs):        return self._filesource = FakeSocket(http_response_str)response = HTTPResponse(source)response.begin()print "status:", response.statusprint "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

从中导入

http.client

，并且要解析的响应需要进行字节编码。根据从何处获取数据，可能已经完成或需要显式调用

from http.client import HTTPResponsefrom io import BytesIOhttp_response_str = """HTTP/1.1 200 OKDate: Thu, Jul  3 15:27:54 2014Content-Type: text/xml; charset="utf-8"Connection: closeContent-Length: 626teststring"""http_response_bytes = http_response_str.enpre()class FakeSocket():    def __init__(self, response_bytes):        self._file = BytesIO(response_bytes)    def makefile(self, *args, **kwargs):        return self._filesource = FakeSocket(http_response_bytes)response = HTTPResponse(source)response.begin()print( "status:", response.status)# status: 200print( "single header:", response.getheader('Content-Type'))# single header: text/xml; charset="utf-8"print( "content:", response.read(len(http_response_str)))# content: b'teststring'
