如何分析PHP中的标题 [英] How to analyze headers in PHP

问题描述

我正在使用 file_get_contents 与 api 进行交互以处理简单的 GET 请求……但是有时它会抛出标头，表明存在错误.如何获取这些标题并确定是否存在问题?

I'm using a file_get_contents to interact with an api for simple GET requests... however sometimes it throws headers signifying there's been an error. How can I get these headers and determine if there's a problem?

推荐答案

使用 curl 而不是 file_get_contents.

Use curl instead of file_get_contents.

参见:http://www.php.net/manual/en/curl.examples-basic.php

我想如果您与 REST Api 通信，那么您实际上希望返回 Http 状态代码.在这种情况下，您可以执行以下操作:

I imagine if your communicating with a REST Api then your actaully wanting the Http Status code returned. In which case you could do something like this:

<?php
$ch = curl_init("http://www.example.com/api/users/1");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
if(curl_getinfo($ch, CURLINFO_HTTP_CODE) == 501) {
    echo 'Ops it not implemented';
}
fclose($fp);
?>
