API卷曲响应问题php

问题描述

我无法处理Companies House API的回复。我正在从PHP 页面发出以下curl请求：

$request_url_1 ='https://api.companieshouse.gov.uk/company/' ;
$company_number = 11495745;
$request_url_2 = '/officers';
$request_url = $request_url_1 . $company_number . $request_url_2;   
  $ch = curl_init($request_url); 
  $headers = array(
    'Content-Type: application/json','Authorization: Basic '. base64_encode("$chkey:")
);
curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
  $content = curl_exec($ch); 
  curl_close( $ch ); 
  $contents = json_decode($content,true);

以下是发送curl请求后在PHP 页面上“粘贴”的响应，我似乎无法获得应包含curl响应的$ contents变量的内容/值。

我尝试将结果作为非关联数组返回并通过普通数组访问它，但那里也没有乐趣。

FluffyKitten提供了以下代码来执行名称字段的提取：

$item = $contents["items"];
foreach($item as $items){
    echo $items["name"];
}

但是，这无法访问所需的数据。 $ contents的print_r结果为'1'，并且var_dump（1）

解决方法

您的代码有几个问题：

您正在混淆用于访问数组和对象的代码
在不需要循环的情况下循环播放

您正在使用json_decode($content,true)，并通过传递该true参数将结果转换为关联数组，但随后尝试将items作为对象的属性进行访问

由于已将内容转换为关联数组，因此可以使用正确的键轻松访问所需的信息，例如：

$item = $contents["items"];
foreach($item as $items){
    echo "<p>".$items["name"];
}

参考 PHP json_decode Documentation

更新：

您的问题已经完全改变-它是关于如何遍历变量与结果的关系，但是现在看来，问题首先是将结果另存为变量。

您需要将CURLOPT_RETURNTRANSFER option设置为true，以免直接输出结果（我想这就是您将结果“粘贴”到PHP页面中的意思）。

将此代码添加到您的CURL代码中，然后如果其余代码正确无误，则应将结果保存在$content变量中，以便您可以使用它循环遍历上面的代码：

curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
