Google登录PHP

Question

我正在添加谷歌登录到我的网站。我遵循的步骤这里没有任何问题，只有当我使用后端服务器进行身份验证得到一个错误(500个内部服务器错误)。

我正在使用下载发布说明并下载google-api-php-client-2.2.3.zip。我不确定这是否相关，但是服务器上安装的PHP版本是PHP5.2.17版本

解压缩后，文件的内容(src、供应商、composer.json等)都会被移动到我的项目的根文件夹并上传到服务器。

HTML直接从使用说明中复制和粘贴，以尽量减少我端的人为错误。

function onSignIn(googleUser) {
    var id_token = googleUser.getAuthResponse().id_token;
    // console.log(id_token);

    var xhr = new XMLHttpRequest();
    xhr.open('POST', 'googleauth.php');
    xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
    xhr.onload = function() {
        console.log('Signed in as: ' + xhr.responseText);
    };
    xhr.send('idtoken=' + id_token);

    var profile = googleUser.getBasicProfile();
    sessionStorage.refName = profile.getId();
    // console.log('ID: ' + profile.getId()); // Do not send to your backend! Use an ID token instead.
    // console.log('Name: ' + profile.getName());
    // console.log('Image URL: ' + profile.getImageUrl());
    // console.log('Email: ' + profile.getEmail()); // This is null if the 'email' scope is not present.
}

function signOut() {
    sessionStorage.clear();
    var auth2 = gapi.auth2.getAuthInstance();
    auth2.signOut().then(function () {
        console.log('User signed out.');
    });
}

<?php
    require_once 'vendor/autoload.php';

    $id_token = $_POST["idtoken"];
    echo 'test2';
?>

当我注释掉‘performs /autooload.php’文件中的代码而只让它返回" test1“时，require_once成功地执行了它的功能，并成功地登录到控制台。但是，当我运行最初由Google编写的脚本时，我会得到一个500 (内部服务器错误)，并将“登录为：”登录到控制台。

这个api中有这么多文件，我发现它不可能导航。而且我也很难相信Google会以一种无法直接发挥作用的方式发布如此重要的东西。

从我的角度来看，我认为我是逐字逐句地执行指令，但有没有人对他们认为我可能误解了什么，或者我可以尝试什么不一样有任何建议？

编辑从服务器添加错误日志(用$标记替换个人信息)

Answer 1

我重读了API注释，结果发现PHP版本确实很重要.

要求: PHP 5.4.0或更高版本

我已经更新了服务器上使用的版本，不再收到任何错误
