Python 如何构造webob.Request或WSGI'；环境'；来自原始HTTP请求字节流的dict？

假设我有一个字节流，其中包含以下内容：

POST /mum/ble?q=huh Content-Length: 18 Content-Type: application/json; charset="utf-8" Host: localhost:80 ["do", "re", "mi"] POST/mum/ble？q=huh 内容长度：18 内容类型：application/json；charset=“utf-8” 主机：本地主机：80 [“do”、“re”、“mi”]

---

为此目的重用Python的标准库代码有点棘手（它不是设计成这样重用的！-），但应该是可行的，例如：

import cStringIO
from wsgiref import simple_server, util

input_string = """POST /mum/ble?q=huh HTTP/1.0
Content-Length: 18
Content-Type: application/json; charset="utf-8"
Host: localhost:80

["do", "re", "mi"]
"""

class FakeHandler(simple_server.WSGIRequestHandler):
    def __init__(self, rfile):
        self.rfile = rfile
        self.wfile = cStringIO.StringIO() # for error msgs
        self.server = self
        self.base_environ = {}
        self.client_address = ['?', 80]
        self.raw_requestline = self.rfile.readline()
        self.parse_request()

    def getenv(self):
        env = self.get_environ()
        util.setup_testing_defaults(env)
        env['wsgi.input'] = self.rfile
        return env

handler = FakeHandler(rfile=cStringIO.StringIO(input_string))
wsgi_env = handler.getenv()

print wsgi_env

基本上，我们需要对请求处理程序进行子类化，以伪造通常由服务器为其执行的构造过程（

rfile

和

wfile

从套接字构建到客户端，等等）。我认为这还不太完整，但应该很接近，我希望它能有所帮助

请注意，我还修复了您的示例HTTP请求：如果原始请求行末尾没有

HTTP/1.0

或1.1，则

POST

被视为格式不正确，并在

handler.wfile

上导致异常和错误消息，谢谢，Alex，它的工作方式与宣传的一样。我还通过webob.Request.str\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。因此，在执行“handler=FakeHandler（…）”之后，最好执行“del handler.server”。@offby1，一个引用循环（由

self.server=self

创建）不是内存泄漏，因为Python确实对引用循环进行了垃圾收集；如果你能明智地打破循环，那将通过避免

gc

pass来加快速度。 POST /mum/ble?q=huh Content-Length: 18 Content-Type: application/json; charset="utf-8" Host: localhost:80 ["do", "re", "mi"]

import cStringIO
from wsgiref import simple_server, util

input_string = """POST /mum/ble?q=huh HTTP/1.0

Content-Type: application/json; charset="utf-8"
