JSON解码显示“Array”

本文介绍了JSON解码显示“Array”的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

这部分：

$ response_2 = json_decode（$ response_2，true）;

...下面的代码在浏览器中被称为Array。如果我删除部分，完整的$ response_2在浏览器中以JSON格式回显，就像这个例子： developer.spotify/web-api/get-list-users-playlists/

如何

<？php $ url ='https：//accounts.spotify。 com / api / token'; $ method ='POST'; $ credentials =hidden：hidden; $ headers = array（Accept：* / *，Content-Type：application / x-www-form-urlencoded，授权：基本。base64_encode（$ credentials））; $ data ='grant_type = client_credentials'; $ ch = curl_init（）; curl_setopt（$ ch，CURLOPT_URL，$ url）; curl_setopt（$ ch，CURLOPT_HTTPHEADER，$ headers）; curl_setopt（$ ch，CURLOPT_POST，1）; curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ data）; curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）; $ response = curl_exec（$ ch）; curl_close（$ ch）; $ response = json_decode（$ response，true）; $ token = $ response ['access_token']; echo我的令牌是：。 $ token; $ headers_2 = array（Accept：* / *，Content-Type：application / x-www-form-urlencoded 'Authorization：Bearer'。$ token））; $ ch = curl_init（）; curl_setopt（$ ch，CURLOPT_URL，'https：//api.spotify/v1/users/wizzler/playlists'）; curl_setopt（$ ch，CURLOPT_HTTPHEADER，$ headers_2）; curl_setopt（$ ch，CURLOPT_POST，false）; curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）; $ response_2 = curl_exec（$ ch）; curl_close（$ ch）; $ response_2 = json_decode（$ response_2，true）; echo $ response_2; ？>当你使用 echo

在数组上，它只是打印出字符串 Array 。这只是PHP的一个奇怪。

如果要打印数组的内容，可以使用 print_r（）或 var_dump（）。

但是，你真正想要做的是打印JSON，这是字符串。 $ response_2 已是一个字符串，因此请将其打印出来。

This part:

$response_2 = json_decode($response_2, true);

...of the code below is echoed literally as "Array" in the browser. If I remove the part, the full $response_2 is echoed in browser in JSON-format just like in this example: developer.spotify/web-api/get-list-users-playlists/

How come?

<?php $url = 'accounts.spotify/api/token'; $method = 'POST'; $credentials = "hidden:hidden"; $headers = array( "Accept: */*", "Content-Type: application/x-www-form-urlencoded", "Authorization: Basic " . base64_encode($credentials)); $data = 'grant_type=client_credentials'; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response = curl_exec($ch); curl_close($ch); $response = json_decode($response, true); $token = $response['access_token']; echo "My token is: " . $token; $headers_2 = array( "Accept: */*", "Content-Type: application/x-www-form-urlencoded", ('Authorization: Bearer ' . $token)); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,'api.spotify/v1/users/wizzler/playlists'); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers_2); curl_setopt($ch, CURLOPT_POST, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response_2 = curl_exec($ch); curl_close($ch); $response_2 = json_decode($response_2, true); echo $response_2; ?>

解决方案

When you use echo on an array, it just prints out the literal string Array. This is just a quirk of PHP.

If you want to print out the contents of the array, you can use print_r() or var_dump().

However it seems like what you actually want to do is print the JSON, which is the string. $response_2 is already a string, so print it out.
