cURL命令到Unity的web請求

我有一個 JSON 結構如下：

{
    "values": {
        "AppName": "Test001",
        "AppUser": "Testttt"
    },
    "consentAccepted": true,
    "consentToken": "adgrtztzEZKo3LD56Hjo8LiqeoQ2Z5 ik0loplr"
}

上面的 JSON 在https://web.postman.co/ 中有效，我的狀態為成功。

我想用 POST 嘗試使用 Unity 的 WebRequest 來填寫“AppName”和“AppUser”以及令牌。我如何實作這一目標？

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;

public class SendData: MonoBehaviour {

void Update () {
        if (InputCompat.GetKeyDown (KeyCode.P)) {
            StartCoroutine ("FillAndSend");
        }
    }
public IEnumerator FillAndSend() {
        WWWForm form = new WWWForm ();

        form.AddField ("AppName", "Testttt");
        form.AddField ("AppUser", "Reinnn");

        UnityWebRequest www = UnityWebRequest.Post ("https://mywebsite.com/profile/MyApp", form);
        www.SetRequestHeader ("token", "tz677zuiuis2qEZKo3Lt kHluOGss");
        yield return www.SendWebRequest ();
        if (www.isNetworkError || www.isHttpError) {
            Debug.Log (www.error);
        } else {
            Debug.Log (www.downloadHandler.text);
        }
    }
}

我收到一個名為 HTTP 內部服務器錯誤的錯誤。它有什么問題？與此同時，我必須添加一個特定的引數，如下所示：

formToken: MyApp

看起來form你更想發送一個 JSON 字串而不是一個。

就像是

var json = "{\"values\": {\"AppName\":\"Test001\",\"AppUser\":\"Rein\"}, \"consentAccepted\":true, \"consentToken\":\"tz677zuiuis2qEZKo3Lt kHluOGss\"}";
var jsonBytes = Encoding.UTF8.GetBytes(json);

using (var www = new UnityWebRequest("https://mywebsite.com/profile/MyApp", "POST"))
{
    www.uploadHandler = new UploadHandlerRaw(jsonBytes);
    www.downloadHandler = new DownloadHandlerBuffer();
    www.SetRequestHeader("Content-Type", "application/json");
    www.SetRequestHeader("Accept", " text/plain");
    
    yield return www.SendWebRequest();

    if (www.isNetworkError || www.isHttpError)
    {
        Debug.Log(www.error);
    }
    else
    {
        Debug.Log(www.downloadHandler.text);
    }
}

為了輕松地配置它，例如通過 Inspector 或傳遞值而不必手動撰寫 JSON，您可以輕松地擁有一個類，例如

[Serializable]
public class PostData
{
    public Values values;
    public bool consentAccepted;
    public string consentToken;
}

[Serializable]
public class Values
{
    public string AppName;
    public string AppUser;
}

然后簡單地做例如

var jsonData = new PostData
{
    values = new Values
    {
        AppName = "Test001",
        AppUser = "Rein"
    },
    consentAccepted = true,
    consentToken = "tz677zuiuis2qEZKo3Lt kHluOGss"
}
var json = JsonUtility.ToJson(jsonData);
var jsonBytes = Encoding.UTF8.GetBytes(json);

用戶derHugo的解決方案是對的，只是代碼中的JSON結構有誤。我修復了它，這是完整的解決方案。

private string json = @"{
        'values': {
        'AppName': 'Test001',
        'AppUser': 'Rein'
    },
    'consentAccepted': true,
    'consentToken': 't65wRU6rttK1klzu768'
    }";

var jsonBytes = Encoding.UTF8.GetBytes(json);

using (var www = new UnityWebRequest("https://mywebsite.com/profile/MyApp", "POST"))
{
    www.uploadHandler = new UploadHandlerRaw(jsonBytes);
    www.downloadHandler = new DownloadHandlerBuffer();
    www.SetRequestHeader("Content-Type", "application/json");
    www.SetRequestHeader("Accept", " text/plain");
    
    yield return www.SendWebRequest();

    if (www.isNetworkError || www.isHttpError)
    {
        Debug.Log(www.error);
    }
    else
    {
        Debug.Log(www.downloadHandler.text);
    }
}
