    return render_template("wx.html")
 
 
if __name__ == "__main__":
    app.run(debug=True)

2. wx.html代码


<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title></title>
    <script src="static/jquery-1.12.4.min.js"></script>
</head>
<body>
<button id="wx_login">微信登录</button>
<script>
    $("#wx_login").click(function () {
        {#let url = encodeURIComponent(window.location.href); // 注意一定要encodeURIComponent#}
        let url = encodeURIComponent("http://127.0.0.1:5000/role"); // 注意一定要encodeURIComponent
        let url2 =
            `https://open.weixin.qq.com/connect/oauth2/authorize?appid=wxa77a00333cd8d99a&redirect_uri=${url}&response_type=code&scope=snsapi_userinfo&state=#wechat_redirect`
        window.location.href = url2
    })
</script>
</body>
</html>

3. index.html代码
