C#向web服務器上傳圖片和視頻

1、解釋說明：

WWWFORM.AddBinaryData（string fieldName，byte [] contents，string fileName = null，string mimeType = null）；

包含四個參數重載：

string fieldName:字段名(也就是表單元素的name，類似於html表單的) ；

byte [] contents：二進制數據（文件轉換的二進制數據）；

string fileName = null：文件名（即交託服務器的文件名稱，包含文件後綴，如果爲空，服務器會默認文件爲dat類型）；

如果mimeType沒有給出，並且數據的前8個字節與PNG格式標題匹配，則數據以“ image/png”mimetype 發送。否則它將以“ application/octet-stream”mimetype 發送。

實際應用中給定前三個參數就足夠了；

方法一：
//public Image imgae;
string url = “http://192.168.3.122”;
//string CreateURL = “http://192.168.3.122//CreatFolder.php”;
//string DelURL = “http://192.168.3.122//DelFolder.php”;

    string PicturePath = @"file://D:\EmergencySinglePlayerEditor\Assets\Art\Texture\UI\大海.jpg";

    public RawImage myRaw;

    public Texture2D m_uploadImage;


    [AddBindPath( "UpVideoBtn" )]
    [SerializeField]
    private Button m_UpVideoBtn;

    [AddBindPath( "UpSpriteBtn" )]
    [SerializeField]
    private Button m_UpSpriteBtn;

    private void Awake()
    {
        StartCoroutine( ReadPic() );
    }

    IEnumerator ReadPic()
    {
        WWW www = new WWW( PicturePath );
        yield return www;
        if ( www.error != null )
        {
           // m_info = www.error;
            yield return null;
        }
        m_uploadImage = www.texture;
    }



    public override void Init()
    {
       
        m_UpVideoBtn.onClick.AddListener( UpVideo );
        m_UpSpriteBtn.onClick.AddListener( UpSprite );
    }

方法二：

string DelURL = "http://。。。。/DelFolder.php";

}

//創建文件夾
IEnumerator CreatFolder( string FolderName )
{

    wForm.AddField( "FolderName", FolderName );
    WWW w = new WWW( CreateURL, wForm );
    yield return w;
    if ( w.isDone )
    {

    }
}

//刪除文件夾
IEnumerator DelFolder( string FolderName )

    WWW w = new WWW( DelURL, wForm );
    yield return w;
    if ( w.isDone )

    }
}

//上傳圖片到指定的文件夾
IEnumerator Upload()

    byte[] bytes = SpriteToBytes( imgae.sprite );//獲取圖片數據
    WWWForm form = new WWWForm();//創建提交數據表單
    form.AddField( "folder", "Photos/" );//定義表單字段用來定義文件夾

}

//獲取圖片的二進制數據

    byte[] bytes = t.EncodeToJPG();
    return bytes;
}
