表格提交后(python服务器，html表单)之后，空心主体

Question

我当前正在尝试为网站用户构建基于Web的身份验证系统。这是我的html-login形式：

<form action="/auth" method="post" class="pure-form pure-form-stacked">
    <fieldset>
        <legend>Login</legend>
        <label for="username">Username</label>
        <input id="username" type="username" placeholder="Username">
        <label for="password">Password</label>
        <input id="password" type="password" placeholder="Password">
        <button type="submit" class="pure-button pure-button-primary">
            Login
        </button>
    </fieldset>
</form>

通常，我期望它将请求发送到服务器，并在请求正文中两个凭据，因此我/auth路线可以检查它们。但是，我使用的方法的解析器似乎在请求主体中似乎找不到任何东西。这是我的Request-parser（它检查了参数后的部分：

class Request:
    """
    http request data.
    """
    def __init__(self):
        self.headers = {}
        self.method = None
        self.protocol = None
        self.resource = None
        self.path = None
        self.params = {}
        self.origin = None  # will be set from server
    def parse(self, conn):
        """Parses an http-Request and return a dictionary with process_request line values and headers."""
        self.headers = {}
        # read process_request line
        request_line = conn.readline().decode('utf-8').strip()
        log(1, "Request-Line: %s" % request_line)
        if not request_line:  # rfc says "server SHOULD ignore blank request lines"
            return None
        # parse process_request line
        try:
            self.method, self.resource, self.protocol = request_line.split(" ")
        except ValueError:
            raise StopProcessing(400, "Bad request-line: %sn" % request_line)
        # parse resource to path and params
        # extract GET parameters
        from urllib.parse import urlparse, parse_qs # analyse urls and parse query strings
        requrl = urlparse(self.resource)
        self.path = requrl.path
        self.params.update(parse_qs(requrl.query))
        # read and parse Request-Headers
        while True:
            header_line = conn.readline().decode('utf-8').strip()
            if not header_line:
                break
            log(2, "Header-Line: " + header_line)
            (headerfield, headervalue) = header_line.split(":", 1)
            self.headers[headerfield.strip()] = headervalue.strip()
        # read cookies
        if 'Cookie' in self.headers:
            log(2, "Cookie ist: %s" % self.headers['Cookie'])
            self.cookies = Cookie.parse(self.headers['Cookie'])
        else:
            self.cookies = {}
        # parse POST parameters
        log(1,"Methode %s" % self.method)
        if self.method == 'POST' or self.method == 'post':
            postbody = conn.read(int(self.headers['Content-Length'])).decode('utf-8')
            self.params.update(parse_qs(postbody))
        # all parameter values are lists
        # replace lists by the only element if there is only one
        for key in self.params:
            if len(self.params[key])==1:
                self.params[key] = self.params[key][0]
        return self.headers

我在代码的关键段落中添加了一些跟踪输出，我发现我的解析器总是返回一个空词典{}。我想念什么？该框架中没有任何附加组件。它是纯Python。

您需要在表单输入上设置name属性，id无法识别表单上的输入。
