Laravel 5:从 $request 中检索 JSON 数组 [英] Laravel 5: Retrieve JSON array from $request

问题描述

我是 Laravel 新手，我正在将一个 php/jquery 应用程序转换为 Laravel.原始代码使用了一个带有 ajax POST 的 JSON 数组，它是这样检索的:

$json = file_get_contents('php://input');$data = json_decode($json,true);

我在 POST 方面做了很多相同的事情，但是我在 Laravel $request 集合中没有看到任何数据.我需要做些什么来检索这样结构的 JSON 数据:

<预><代码>[{ "name": "John", "location": "Boston" },{ "name": "Dave", "location": "Lancaster" }]

这是我的 jQuery ajax POST 代码(带有硬编码数据)

$.ajax({类型:POST"，网址:/人"，数据:'[{姓名":约翰"，地点":波士顿"}，{姓名":戴夫"，地点":兰开斯特"}]'，数据类型:json"，成功:功能(数据){$('#save_message').html(data.message);}});

这是我的控制器中接收 POST 的代码

公共函数库(Request $request){dd($request->all());}

但我得到的是:

关于如何检索我的数据的任何想法?

解决方案

您需要将 Ajax 调用更改为

$.ajax({类型:POST"，网址:/人"，数据:'[{姓名":约翰"，地点":波士顿"}，{姓名":戴夫"，地点":兰开斯特"}]'，内容类型:json"，过程数据:假，成功:功能(数据){$('#save_message').html(data.message);}});

将 dataType 更改为 contentType 并添加 processData 选项.

要从控制器检索 JSON 有效负载，请使用:

dd(json_decode($request->getContent(), true));

代替

dd($request->all());

I'm a Laravel newbie and I'm converting a php/jquery app to Laravel. The original code used a JSON array with an ajax POST, which was retrieved like this:

$json = file_get_contents('php://input');
$data = json_decode($json,true);

I'm doing much the same thing on the POST side, but I don't see any data coming through in my Laravel $request collection. Is there something special that I need to do to retrieve JSON data structured like this:

[
    { "name": "John", "location": "Boston" }, 
    { "name": "Dave", "location": "Lancaster" }
]

Here is my jQuery ajax POST code (with hard coded data)

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    dataType: "json",
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

Here is the code in my Controller that receives the POST

public function store(Request $request)
{
    dd($request->all());
}

But all I get is:

[]

Any ideas on how I can retreive my data?

解决方案

You need to change your Ajax call to

$.ajax({
    type: "POST",
    url: "/people",
    data: '[{ "name": "John", "location": "Boston" }, { "name": "Dave", "location": "Lancaster" }]',
    contentType: "json",
    processData: false,
    success:function(data) {
        $('#save_message').html(data.message);
    } 
});

change the dataType to contentType and add the processData option.

To retrieve the JSON payload from your controller, use:

dd(json_decode($request->getContent(), true));

instead of

dd($request->all());
