Unity C# E-learning （ Ten ）——UnityWebRequest（ One ）

UnityWebRequest And WWW The difference between

• UnityWebRequest Split various resources
• UnityWebRequest Than WWW More efficient , Very low GC produce
• More convenient to upload data

One .UnityWebRequest Class to get data

1. Download Text and binary data

    private IEnumerator LoadText()
    {
    
        UnityWebRequest unityWebRequest = UnityWebRequest.Get("http://192.168.1.103:8080/Http_Server/zzs.txt");
        yield return unityWebRequest.SendWebRequest();
        if (unityWebRequest.result == UnityWebRequest.Result.Success)
        {
    
            string text = unityWebRequest.downloadHandler.text;
            byte[] bytes = unityWebRequest.downloadHandler.data;
            Debug.Log(text);
            Debug.Log(bytes.Length);
            Debug.Log(" Text download complete !");
        }
        else
        {
    
            Debug.Log(" Download failed :" + unityWebRequest.result);
        }
    }

2. Download image data

    private IEnumerator LoadTexture()
    {
    
        UnityWebRequest unityWebRequest =
            UnityWebRequestTexture.GetTexture("http://192.168.1.103:8080/Http_Server/xxx.jpg");
        yield return unityWebRequest.SendWebRequest();
        if (unityWebRequest.result == UnityWebRequest.Result.Success)
        {
    
            // Mode one 
            Texture2D tex2D1 = (unityWebRequest.downloadHandler as DownloadHandlerTexture)?.texture;
            // Mode two 
            Texture2D tex2D2 = DownloadHandlerTexture.GetContent(unityWebRequest);
            image.texture = tex2D2;
            Debug.Log(" Picture download completed !");
        }
        else
        {
    
            Debug.Log(" Download failed :" + unityWebRequest.result);
        }
    }

3. download AssetBundle data

    private IEnumerator LoadAb()
    {
    
        UnityWebRequest unityWebRequest =
            UnityWebRequestAssetBundle.GetAssetBundle("http://192.168.1.103:8080/Http_Server/photo.ywj");
        unityWebRequest.SendWebRequest();
        while (!unityWebRequest.isDone)
        {
    
            Debug.Log(unityWebRequest.downloadProgress);
            Debug.Log(unityWebRequest.downloadedBytes);
            yield return null;
        }

        if (unityWebRequest.result == UnityWebRequest.Result.Success)
        {
    
            // Mode one 
            AssetBundle assetBundle1 = (unityWebRequest.downloadHandler as DownloadHandlerAssetBundle)?.assetBundle;
            // Mode two 
            AssetBundle assetBundle2 = DownloadHandlerAssetBundle.GetContent(unityWebRequest);

            if (assetBundle1 != null) Debug.Log(assetBundle1.name);
            if (assetBundle2 != null) Debug.Log(assetBundle2.name);
            Debug.Log(" Picture download completed !");
        }
        else
        {
    
            Debug.Log(" Download failed :" + unityWebRequest.result);
        }
    }

4. Download audio data

    private IEnumerator LoadAudioClip()
    {
    
        UnityWebRequest unityWebRequest =
            UnityWebRequestMultimedia.GetAudioClip("http://192.168.1.103:8080/Http_Server/music.mp3", AudioType.MPEG);
        yield return unityWebRequest.SendWebRequest();
        if (unityWebRequest.result == UnityWebRequest.Result.Success)
        {
    
            AudioClip clip = DownloadHandlerAudioClip.GetContent(unityWebRequest);
            audioSource.clip = clip;
            audioSource.Play();
            Debug.Log(" Audio download succeeded !");
        }
        else
        {
    
            Debug.Log(" Download failed :"+unityWebRequest.result);
        }
    }

Two .UnityWebRequest Class upload data

1. Upload data class MultipartFormDataSection

		//======MultipartFormDataSection======
        //1. Binary byte array 
        dataList.Add(new MultipartFormDataSection(Encoding.UTF8.GetBytes("zzs666")));
        //2. character string 
        dataList.Add(new MultipartFormDataSection("zzs666"));
        //3. Parameter name , Parameter values 
        dataList.Add(new MultipartFormDataSection("Name","zzs"));
        dataList.Add(new MultipartFormDataSection("Msg",new byte[1024]));

2. Upload data class MultipartFormFileSection

        //======MultipartFormFileSection======
        //1. Binary byte array 
        dataList.Add(new MultipartFormFileSection(Encoding.UTF8.GetBytes("zzs666")));
        //2. file name , Byte array （ Commonly used ）
        dataList.Add(new MultipartFormFileSection(" Uploaded files .jpg",File.ReadAllBytes(Application.streamingAssetsPath +"/test.jpg")));
        //3. String data , Coding format , file name （ Commonly used ）
        dataList.Add(new MultipartFormFileSection("zzs!zzs!zzs!",Encoding.UTF8, "zzsTest.txt"));

3.Post Send data related

    private IEnumerator UpLoad()
    {
    
        List<IMultipartFormSection> data = new List<IMultipartFormSection>
        {
    
            new MultipartFormDataSection("Name", "MrTang"),
            new MultipartFormFileSection("Unity Uploaded files .jpg",
                File.ReadAllBytes(Application.streamingAssetsPath + "/test.jpg")),
            new MultipartFormFileSection("zzs!zzs!zzs!", Encoding.UTF8, "zzsTest.txt")
        };
        UnityWebRequest unityWebRequest = UnityWebRequest.Post("http://192.168.1.103:8080/Http_Server/", data);
        yield return unityWebRequest.SendWebRequest();

        if (unityWebRequest.result == UnityWebRequest.Result.Success)
        {
    
            Debug.Log(" Upload to complete !");
        }
        else
        {
    
            Debug.Log(" Upload failed !" + unityWebRequest.result + unityWebRequest.error);
        }
    }
