返回的HTTP状态codeS用REST API [英] Returning http status codes with a rest api

问题描述

我建立我自己的REST API在PHP实践。我可以评估发送到我的API（POST，PUT，DELETE，得到）的HTTP code。但是，当我发出我的回答我真的我只是打印出一个JSON。例如，我建立像这样我的API响应

I am building my own rest api in php for practice. I can evaluate the http code sent to my api (post,put,delete,get). But when I send out my response I really am just printing out a json. For example, I build a response in my api like this

    public function actionTest()
    {
        $rtn=array("id":"3","name":"John");
        print json_encode($rtn);
    }

我无论如何也不能操纵头。从阅读计算器，我知道我应该返回的HTTP响应codeS符合我的API的结果。我怎样才能建立在我的API和返回响应codeS。我只是不明白我怎么能做到这一点，因为现在我只是打印出一个JSON。

I am not manipulating the headers in anyway. From reading stackoverflow, I understand that I should be returning http response codes to match my api results. How can I build on my api and return the response codes. I just don't understand how I can do it because right now I am just printing out a json.

我不要求其codeS返回。我只是想知道如何在一般的C $ CS返回$。

I am not asking which codes to return. I just want to know how to return codes in general.

推荐答案

您可以重新考虑你的code这样

You could re-think your code this way

public function actionTest()
{
    try {
        // Here: everything went ok. So before returning JSON, you can setup HTTP status code too
        $rtn = array("id", "3", "name", "John");
        http_response_code(200);
        print json_encode($rtn);
    }
    catch (SomeException $ex) {
        $rtn = array("id", "3", "error", "something wrong happened");
        http_response_code(500);
        print json_encode($rtn);
    }
}

基本上，前流的输出（JSON数据），你可以通过设置 http_response_ code（$code）功能。

和有关意见的另一个问题，是的，打印的JSON数据是正确的方式。

And about your additional question in comment, yes, printing the JSON data is the correct way.
