在 PHP 中调用 REST API [英] Call a REST API in PHP

问题描述

我们的客户给了我一个 REST API，我需要对它进行 PHP 调用.但实际上API给出的文档非常有限，所以我真的不知道如何调用服务.

Our client had given me a REST API to which I need to make a PHP call to. But as a matter of fact the documentation given with the API is very limited, so I don't really know how to call the service.

我试过用谷歌搜索，但唯一出现的是一个已经过期的 Yahoo!关于如何调用服务的教程.没有提到标题或任何深入的信息.

I've tried to Google it, but the only thing that came up was an already expired Yahoo! tutorial on how to call the service. Not mentioning the headers or anything in depth information.

是否有关于如何调用 REST API 的合适信息或有关它的一些文档?因为即使在 W3schools 上，他们也只描述了 SOAP 方法.在 PHP 中制作 rest API 有哪些不同的选择?

Is there any decent information around how to call a REST API, or some documentation about it? Because even on W3schools, they only describes the SOAP method. What are different options for making rest API in PHP?

推荐答案

您可以使用 PHPs cURL 扩展访问任何 REST API.但是，API 文档(方法、参数等)必须由您的客户提供！

You can access any REST API with PHPs cURL Extension. However, the API Documentation (Methods, Parameters etc.) must be provided by your Client!

示例:

// Method: POST, PUT, GET etc
// Data: array("param" => "value") ==> index.php?param=value

function CallAPI($method, $url, $data = false)
{
    $curl = curl_init();

    switch ($method)
    {
        case "POST":
            curl_setopt($curl, CURLOPT_POST, 1);

            if ($data)
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            break;
        case "PUT":
            curl_setopt($curl, CURLOPT_PUT, 1);
            break;
        default:
            if ($data)
                $url = sprintf("%s?%s", $url, http_build_query($data));
    }

    // Optional Authentication:
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_USERPWD, "username:password");

    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

    $result = curl_exec($curl);

    curl_close($curl);

    return $result;
}
