玩框架路由麻烦(400错误请求) [英] play framework routes trouble (400 bad request)

问题描述

我在对Play框架进行POST时遇到了麻烦-可能与Play的关联性不如HTTP.

I'm having trouble making a POST to the play framework - this may not even be Play related as much as HTTP related.

$.ajax({
    type:'POST',
    url:'http://localhost:9000/start',
    data: {
        myJson:JSON.stringify(arg)
    }
}).done(function(data) {
    console.log(data);
});

其中，arg是字符串数组，即: ['a', 'b', 'c']

where arg is an array of strings, ie: ['a', 'b', 'c']

我试图用来捕获的路由是:

The route I'm trying to use to capture this is:

POST    /start      controllers.Application.startIt(myJson)

我做错了什么?截至目前(如果路线已正确捕获)，该函数将永远不会返回400.Play控制台没有输出，只有javascript:

What am I doing wrong? As of right now (if the route is capturing correctly), that function will never return a 400. There is no output to the Play console, only javascript:

POST http://localhost:9000/start 400 (Bad Request)

推荐答案

文档说明了BadRequest何时出现错误代码由框架返回.问题来自您的路由器文件.您定义了一条路由/start ，该路由将触发方法调用 startIt ，但是该方法有一个参数，框架不知道应该传递哪个值.

The documentation explains when a BadRequest error code is returned by the framework. The problem comes from your router file. You define a route /start which will trigger a method call startIt, but the method has an argument and the framework does not know which value it should pass.

要正确处理JSON请求，请查看文档的专用部分

To handle correctly JSON requests, have a look to the dedicated part of the documentation.
