Cordova Phonegap文件传输上传图像到Webservice

Cordova Phonegap文件传输上传图像到Webservice,cordova,upload,Cordova,Upload,我需要使用phonegaps摄像头和文件传输API将图像上传到Web服务 例如,在Web服务上: [WebMethod] [ScriptMethod(UseHttpGet = true)] public string SaveImage(string imageData, string filename) { string success = "Nothing"; try

我需要使用phonegaps摄像头和文件传输API将图像上传到Web服务

例如,在Web服务上:

[WebMethod]
        [ScriptMethod(UseHttpGet = true)]
        public string SaveImage(string imageData, string filename)
        {

            string success = "Nothing";

            try
            {
                string filename = "text.png";
                if (!System.IO.Directory.Exists(HttpContext.Current.Server.MapPath("~/devimg")))
                {
                    System.IO.Directory.CreateDirectory(HttpContext.Current.Server.MapPath("~/devimg/"));
                }

                string path = HttpContext.Current.Server.MapPath("~/devimg/").ToString();

                byte[] imgByte = Convert.FromBase64String(imageData);

                using (var imgStream = new MemoryStream(imgByte, true))
                {
                    Bitmap img = new Bitmap(imgStream);

                    Image i = (Image)img;
                    i.Save(path + "" + filename, ImageFormat.Png);
                    success = "Image created!!";

                }
            }
            catch (Exception e)
            {
                success = e.ToString();
            }

            return success;
        }
并且在应用程序中有:

navigator.camera.getPicture( function( imgdata ){
    //Base 64 encoded image file or whatever
}, CameraError , {
    quality: 50,
    destinationType: navigator.camera.DestinationType.DATA_URL,
    sourceType: navigator.camera.PictureSourceType.CAMERA,
    encodingType: navigator.camera.EncodingType.JPEG,
    saveToPhotoAlbum: true
});
我目前使用的Web服务允许将一个Base64编码的图像传递给它,然后它将创建图像并使用给定的文件名保存它。但是如果我尝试从phonegap应用程序访问Web服务,它就不起作用了


我曾试图通过ajax访问Web服务,但总是遇到一些错误。是否有更好的方法将图像上载到服务器?

由于我无法选择注释作为答案,以下是我的代码,以供将来参考: Phonegap-JS:

navigator.camera.getPicture( function( imgdata ){
 var urlimg = "http:// *URL ADDRESS* /mobile.asmx/SaveImage";

 var params = new Object();
 params.otherinfo = "Whaterver"
 var options = new FileUploadOptions();
 options.fileKey = "file";
 options.fileName = imgdata.substr(imgdata.lastIndexOf('/')+1);
 options.mimeType = "image/jpeg";
 options.params = params;
 options.chunkedMode = false;

var ft = new FileTransfer();
 setTimeout(function() {
  ft.upload(imgdata, urlimg, function(){
   alert("Success")
  }, function(err){
  alert("Error: " + JSON.stringify(err));
  }, options );
 }, 600);

}, function(err){
 alert(err);
} , {
 quality: 50,
 destinationType: navigator.camera.DestinationType.FILE_URI,
 sourceType: navigator.camera.PictureSourceType.CAMERA,
 encodingType: navigator.camera.EncodingType.JPEG,
 saveToPhotoAlbum: true
});
WebService

[WebMethod]     
public void SaveImage()
{
 if (!System.IO.Directory.Exists(HttpContext.Current.Server.MapPath("~/devimg"))){
  System.IO.Directory.CreateDirectory(HttpContext.Current.Server.MapPath("~/devimg/"));
 }

string path = HttpContext.Current.Server.MapPath("~/devimg/").ToString();

var Request = HttpContext.Current.Request;
if (Request.Files.Count > 0){
 var file = Request.Files[0];
 file.SaveAs( path + file.FileName);
 }
}

看。有关设置文件参数和调用Web服务的详细信息。

选中此选项可通过添加到“我的Web配置”来修复Http\U状态500。单文件上载功能正常,但在同一url中多个文件上载,如何操作?
