每次file_get_contents()从api.github.com获取403 [英] file_get_contents() gets 403 from api.github.com every time

问题描述

我称自己是一位经验丰富的PHP开发人员，但这使我发疯.我试图获取用于显示更新警告的存储库的发行信息，但我一直返回403错误.为了简化它，我使用了GitHub API的最简单用法:GET https://api.github.com/zen.真是个好世界.

I call myself an experienced PHP developer, but this is one drives me crazy. I'm trying to get release informations of a repository for displaying update-warnings, but I keep returning 403 errors. For simplifying it I used the most simple usage of GitHubs API: GET https://api.github.com/zen. It is kind of a hello world.

这有效

• 直接在浏览器中
• 在终端中带有普通curl https://api.github.com/zen
• 具有类似 php-github-api 的PHP-Github-API-Class

• directly in the browser
• with a plain curl https://api.github.com/zen in a terminal
• with a PHP-Github-API-Class like php-github-api

这行不通

• 使用来自PHP-Skript的简单file_get_contents()

这是我的整个简化代码:

This is my whole simplified code:

<?php
    $content = file_get_contents("https://api.github.com/zen");
    var_dump($content);
?>

浏览器显示Warning: file_get_contents(https://api.github.com/zen): failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden，变量$content是布尔值和false.

The browser shows Warning: file_get_contents(https://api.github.com/zen): failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden, the variable $content is a boolean and false.

我想我缺少某种http-header-fields，但是我也找不到 API-Docs ，也不会使用我的终端curl调用任何特殊的头文件并起作用.

I guess I'm missing some sort of http-header-fields, but neither can I find those informations in the API-Docs, nor uses my terminal curl-call any special header files and works.

推荐答案

之所以会发生这种情况，是因为GitHub要求您发送UserAgent标头.不需要任何特定的内容.可以做到:

This happens because GitHub requires you to send UserAgent header. It doesn't need to be anything specific. This will do:

$opts = [
        'http' => [
                'method' => 'GET',
                'header' => [
                        'User-Agent: PHP'
                ]
        ]
];

$context = stream_context_create($opts);
$content = file_get_contents("https://api.github.com/zen", false, $context);
var_dump($content);

输出为:

string(35) "Approachable is better than simple."
