Question

我想对后端Flask发出两个发布请求。我昨天成功获得了登录请求，因为我可以在浏览器控制台中看到打印的信息。但是在添加第二个单击事件后，两者均失败。而“登录”帖子和“搜索”帖子请求失败的方式有所不同，因为对于第一个，我可以在控制台中看到“单击”，但是对于第二个则什么也没有。

我也使用了request.get_data（）和request.get_json（），但是一无所获。我已经使用了一种更简单的方法来从Flask获取帖子请求，例如request.form。但是，我仍然很困惑代码有什么问题。

感谢您提供帮助！

下面是.js文件

$(document).ready(function () {

// login, for sending the email and password
$(function () {
    $("form#formLogin").on('click','button#buttonLogin', function () {
        console.log('clicked');
        $.ajax({
            url: "http://127.0.0.1:5000",
            type: "POST",
            data: $('form#formLogin').serialize(),
            contentType: 'json; charset=UTF-8',
            cache: false,
            success: function (response) {
                console.log(response.d);
                console.log("login info sent");
            },
            fail: function (response) {
                console.log(response.d);
                console.log("failed");
            }
        })
    });
})


// search, for executing sql
$(function () {
    $('form#formSearch').on('click', 'button#buttonSearch', function () {
        console.log('begin sending select');

        $.ajax({
            url: "http://127.0.0.1:5000",
            type: "POST",
            data: $('form#formSelect').serialize(),
            contentType: 'json; charset=UTF-8',
            cache: false,
            success: function (response) {
                console.log(response.d);
                console.log("search info sent");
            },
            fail: function (response) {
                console.log(response.d);
                console.log("failed");
            }
        })
    });
})
})
