如何获取HTTP Post请求的JSON内容?

问题描述

我想从我的Unity应用程序向我的Laravel后端发送一个JSON文件.我的发帖请求似乎出了点问题，但我不知道这是什么.

I want to send a JSON file from my Unity application to my Laravel backend. It seems there is something wrong with my post request but I can't figure out what it is.

public void SendRequest()
        {
            // serializable struct
            OfferData data = new OfferData(OfferSize.JUMBO, OfferType.AD, 50, 10);

            StartCoroutine(RequestHandler.Post(API_URL + "shop/store", JsonUtility.ToJson(data), (response) =>
            {
                if (response == null)
                {
                    return;
                }
                // success
                Debug.Log(response);
            }));
        }

JSON:

{
"size":3,
"type":1,
"gold":50,
"gems":10
}

RequestHandler中的post函数:

The post function in the RequestHandler:

public static IEnumerator Post(string uri, string data, Action<string> response)
        {
            UnityWebRequest webRequest = UnityWebRequest.Post(uri, data);
            webRequest.SetRequestHeader("Content-Type", "application/json");

            yield return webRequest.SendWebRequest();

            if (webRequest.isNetworkError)
            {
                Error(webRequest.error);
                response(null);
            }
            else
            {
                response(webRequest.downloadHandler.text);
            }
        }

如果我与Laravel发送 UnityWebRequest ，则会发送成功响应，但是，打印数组(见下文)只是空的. Laravel无法对JSON进行编码.

If I'm sending the UnityWebRequest with Laravel will send a success response, however, the printed array (see below) is just empty. Laravel can not encode the JSON.

这是在我的控制器功能中访问HTTP Post请求的位置:

This is where the HTTP Post request is being accessed in my controller function:

public function store(Request $request)
{
    Log::debug($request->json()->all());
}

使用邮递员会产生哪些预期结果:

Which produces the expected result when using Postman:

array ('size' => 3, 'type' => 1, 'gold' => 50, 'gems' => 10)

使用Unity使用相同的JSON发送类似的请求:

Sending a similar request with the same JSON using Unity:

array ()

当我使用$request->getContent()时，我实际上可以看到我的数据.为什么数组为空?

When I use $request->getContent() I can actually see my data. Why is the array empty?

从邮递员发送时的请求标头:

错误的请求标头

从Unity发送时的请求标头:

我想念什么?请让我知道是否需要更多信息.

推荐答案

我仍然不确定为什么它不能立即使用，但我想出了解决该问题的方法.

I'm still not sure why it doesn't work out of the box but I figured out how to fix this issue.

将原始上传处理程序添加到 UnityWebRequest :

Add a raw upload handler to the UnityWebRequest:

UnityWebRequest webRequest = UnityWebRequest.Post(uri, data);

// Fix: Add upload handler and pass json as bytes array
webRequest.uploadHandler = new UploadHandlerRaw(Encoding.UTF8.GetBytes(data));

webRequest.SetRequestHeader("Content-Type", "application/json");
yield return webRequest.SendWebRequest();

Laravel现在可以正确解析JSON数据.

The JSON data can now be resolved correctly by Laravel.
