如何使用Guzzle和Laravel从JSON响应中提取单个数组值 [英] How to extract individual array values from JSON response using Guzzle and Laravel

问题描述

我正在努力从JSON响应中获取数据.这是我获取数据的代码:

I'm struggling to get data from JSON response. This is my code for getting the data:

$client = new Client;
$r = $client->get("http://my.api.com/get-campaign/" . $id . "?api_token=1235");
$apiResult = json_decode($r->getBody(), true);

dd($apiResult);

我得到这样的东西:

    array:4 [
  "campaign" => array:1 [
    0 => array:3 [
      "manufacturer" => "Sony"
      "product" => "PlayStation 4"
      "created_at" => "2015-07-04T00:00:00+00:00"
    ]
  ]
  "media" => array:2 [
    "video" => "https://my.domain.com/421156.mp4"
    "images" => "https://my.domain.com/tv/thumbs/421156-1.jpg"
  ]
  "statistics" => array:3 [
    "runs" => 172
    "firstseen_at" => "2015-07-04T19:06:41+00:00"
    "lastseen_at" => "2015-07-09T12:04:13+00:00"
  ]
  "broadcasts" => array:172 []
]

如何从此响应中获取单个值?假设我要显示或将"manufacturer"的值分配给另一个变量，并在另一个变量中存储运行次数("runs")?

How can I get single values from this response? Let's say I want to display, or assign to another variable the value of "manufacturer" and in another variable to store number of runs ("runs")?

对于制造商，我试图做这样的事情:

For manufacturer I've tried to do something like this:

dd($apiResult["campaign"]->manufacturer);

但是随后显示错误-试图获取非财产对象！

But then error is shown - trying to get non-property object!

推荐答案

您正在将对象访问与数组访问混合在一起.

You're mixing object access with array access.

$apiResult = json_decode($r->getBody(), true);
dd($apiResult["campaign"][0]["manufacturer"]);

或带有对象

$apiResult = json_decode($r->getBody(), false);
dd($apiResult->campaign[0]->manufacturer);
