jQuery AJAX 和 JSON 格式

发布于07月02日

我有一个期望接收JSON的Web服务，如下所示:

{"first_name":"test","last_name":"teste","email":"moi@someplace.com","mobile":"+44 22 2222 2222", "password":"testing"}

My AJAX call in jQuery:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: {
            first_name: $("#namec").val(),
            last_name: $("#surnamec").val(),
            email: $("#emailc").val(),
            mobile: $("#numberc").val(),
            password: $("#passwordc").val()
        },
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
    });

有没有办法判断我发送数据的格式？我应该没有向服务器发送正确的JSON(这是验证的第一步).

Is my jQuery code sending valid JSON or did I miss something?

推荐答案

您实际上并没有发送JSON.您正在传递一个作为data的对象，但是您需要将该对象串化并传递字符串.

Your dataType: "json" only tells jQuery that you want it to parse the returned JSON, it does not mean that jQuery will automatically stringify your request data.

更改为:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify({
            first_name: $("#namec").val(),
            last_name: $("#surnamec").val(),
            email: $("#emailc").val(),
            mobile: $("#numberc").val(),
            password: $("#passwordc").val()
        }),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
});
