Unity 启动时带参数,网页后端进行数据交互 UnityWebRequest ,Post,Get,Delete

打包后启动.exe带参数

启动传参数可以参考这篇文章: 浏览器调用本地exe(应用程序)方法

Unity准备工作

需要用到这个API

Environment.GetCommandLineArgs()

官方解释:返回包含当前进程的命令行参数的字符串数组
返回值是一个string[],当Length>1的时候就是带参数,注意:在UnityEditor模式也就是编辑器模式会有默认参数返回,Length是大于1的

UnityWebRequest API使用

常用的就是Get与Post,代码比较简单,有的地方传参时需要注意有没有RequestHeader,这个需要进行特殊处理

代码

	IEnumerator IePostRequest(string url, object mRequestData, GetDate getDate)
    {
    
    
        string paramStr = JsonUtility.ToJson(mRequestData);
        byte[] databyte = Encoding.UTF8.GetBytes(paramStr);
        using (var request = new UnityWebRequest(url, UnityWebRequest.kHttpVerbPOST))
        {
    
    
            request.uploadHandler = new UploadHandlerRaw(databyte);
            request.downloadHandler = new DownloadHandlerBuffer();

            request.SetRequestHeader("Content-Type", "application/json;charset=utf-8");
            request.SetRequestHeader("Authorization", "Bearer" + sessionId);
            request.SetRequestHeader("Content-Length", databyte.Length.ToString());

            yield return request.SendWebRequest();

            if (request.result != UnityWebRequest.Result.Success)
            {
    
    
                Debug.Log(request.error);
            }
            else
                getDate(request.downloadHandler.text);
        }
    }

    IEnumerator IeGetRequest(string url, GetDate getDate)
    {
    
    
        using (var request = new UnityWebRequest(url, UnityWebRequest.kHttpVerbGET))
        {
    
    
            request.SetRequestHeader("Content-Type", "application/json");
            request.SetRequestHeader("Authorization", "Bearer" + sessionId);
            request.downloadHandler = new DownloadHandlerBuffer();
            yield return request.SendWebRequest();

            if (request.result != UnityWebRequest.Result.Success)
            {
    
    
                Debug.Log(request.error);
            }
            else
                getDate(request.downloadHandler.text);
        }
    }

其中GetDate getDate是一个委托,用来接收返回的数据

public delegate void GetDate(string data);
