我正在尝试使用 Scrapy 文档中给出的示例代码使用 python 脚本登录网站。这是修改后的代码：

from scrapy.spider import BaseSpider
from scrapy.http import Request,FormRequest

class LoginSpider(BaseSpider):
    name = 'loginspidername'
    start_urls = ['http://example.com/index.php']
    login_page='http://example.com/index.php'

    def parse(self, response):
        return [FormRequest.from_response(response,
                    formdata={'username': 'myname', 'Password': 'mypass'},
                    formxpath='//*[@id="loginblock"]/div/div/form',
                    callback=self.after_login)]

    def after_login(self, response):
        # check login succeed before going on
        if "logout" in response.body:
            print 'logged in'
        else:
            print 'not logged in'
        return

此外，如果需要，这里是 HTML 部分：

<div class="canvas" name="slideblock" id="loginblock" style="display: none;">
    <div class="wrapper">
        <div class="loginFloater">
            <div align="right"><a href="javascript:hideDiv('loginblock');">close(X)</a></div>
            <h2>Login</h2>

            <form method="post" action="login.php">
            <label>Username</label><input class="data" name="username" value="" placeholder="username" type="text"><br>
            <label>Password</label><input class="data" name="password" value="" placeholder="password" type="password"><br>
            <label></label><strong style="display:none ">Wrong Password Try again</strong>
            <label>&nbsp;</label><input type="submit" class="searchButton" value="Login"></form>
            <input type="checkbox" name="rememberme" value="true"> Remember Me<br><br>
            <label>&nbsp;</label><a href="#">Forgot</a> Password?
            Not a member? <a href="javascript:slideDiv('signupblock');">Signup</a> 
            <br>

        </div>
    </div>
</div>

输出始终是“未登录” 就像看起来很简单的代码一样，它根本没有登录。我无法想到代码中可能存在的任何问题。任何形式的帮助表示赞赏。谢谢阅读。

看来你有一个错字：Password应该是password.
