从PlayFramework表单发布JSON数据 [英] Post JSON-Data from PlayFramework form

问题描述

Play Framework提供了一种通过request().body().asJson()访问请求正文中的JSON-Data的方法.使用表单帮助程序不会以JSON格式发布数据.

Play Framework provides a way to access JSON-Data in a request-body via request().body().asJson(). Using form-helpers does not post data in JSON-format.

那么，在播放应用程序中，在将表单数据传递给控制器​​之前，将表单数据转换为json对象的最佳方法是什么?

So, what is the best way, in a play-application, to convert the form-data to a json-object before passing it to the controller?

谢谢.

推荐答案

1.将表单序列化为JSON对象

$.fn.serializeObject = function(){
var o = {};
var a = this.serializeArray();
$.each(a, function() {
    if (o[this.name] !== undefined) {
        if (!o[this.name].push) {
            o[this.name] = [o[this.name]];
        }
        o[this.name].push(this.value || '');
    } else {
        o[this.name] = this.value || '';
    }
});
return o;
};

2.定义内容类型为application/json

2.Define an AJAX request with content type application/json

$.ajaxSetup({
    contentType: "application/json; charset=utf-8" 
});

function request(path, params, method) {
method = method || "POST";

$.ajax({
    url: path,
    type: method,
    data: params,
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function (result) {
        //do something
    },
    error: function (xhr, ajaxOptions, thrownError) {
        //do something
    }
});
}

3.提交表单后发送数据

$(function() {
var url = "/api/route";

$('form').submit(function() {
    var json = JSON.stringify($('form').serializeObject());
    request(url, json);
    return false;
});
});
