Question

我想根据游戏要求在我的网络服务器上传个人资料照片。为了从设备中选择照片，我使用了这个插件： Native Gallery for Android & iOS

我已使用此代码在网络服务器上传照片，但目前我可以在图片视图组件中加载照片，但无法在网络服务器上传。

    IEnumerator PickImage (int maxSize)
{
    Texture2D texture = null;
    NativeGallery.Permission permission = NativeGallery.GetImageFromGallery (( path) => {
        Debug.Log ("Image path: " + path);
        if (path != null) {
            // Create Texture from selected image
            texture = NativeGallery.LoadImageAtPath (path, maxSize);
            if (texture == null) {
                Debug.Log ("Couldn't load texture from " + path);
                return;
            }

            profileImage.sprite = Sprite.Create (texture, new Rect (0f, 0f, texture.width, texture.height), new Vector2 (0.5f, 0.5f), 100f);
        }
    }, "Select an image", "image/*", maxSize);

    if (texture != null) {

        // make texture read and write able
        Texture2D readableTexture = DuplicateTexture(texture);
        Debug.Log ("readable texture width: " + readableTexture.width + " height: " + readableTexture.height);

        WWWForm form = new WWWForm ();
        Debug.Log ("player id: " + DataCollection.localPlayer.PlayerId);
        form.AddField (GameConstants.ARG_UPLOAD_PHOTO_PLAYER_ID, DataCollection.localPlayer.PlayerId);
        form.AddBinaryData (GameConstants.ARG_UPLOAD_PHOTO, readableTexture.GetRawTextureData (), "profilepic.jpg", "image/*");

        Dictionary<string,string> headerDisc = form.headers;

        WWW www = new WWW (GameConstants.API_UPLOAD_PHOTO, form.data, headerDisc);
        yield return www;

        if (www.error == null) {

            Debug.Log ("Data: " + www.text);
            profileImage.sprite = Sprite.Create (texture, new Rect (0f, 0f, texture.width, texture.height), new Vector2 (0.5f, 0.5f), 100f);

        } else {
            Debug.Log ("Error: " + www.error);
        }

    }
    Debug.Log ("Permission result: " + permission);
}

这是我得到的调试输出：

有一些错误在运行，我无法理解，所以请给我一些帮助。

修改按钮单击事件代码，此处我已将图像大小缩小为与Web服务器兼容的设置：

public void OnChangePhotoButtonClick ()
{
    // Don't attempt to pick media from Gallery/Photos if
    // another media pick operation is already in progress
    if (NativeGallery.IsMediaPickerBusy ())
        return;

    // Pick a PNG image from Gallery/Photos
    // If the selected image's width and/or height is greater than 512px, down-scale the image
    StartCoroutine (PickImage (256));
}

如果我使用RestClient或PostMan，那么该图像会正确上传。

以下是用于获取图像的服务器端代码：
