phoneGap API调用摄像头并上传图片

function uploadshow(typeid) {

            // Retrieve image file location from specified source
            navigator.camera.getPicture(uploadPhoto,
                                        function(message) { alert('没有获取到照片'); },
                                        { quality: 50,
                                        destinationType: navigator.camera.DestinationType.FILE_URI,
                                       // sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY
           sourceType: // 1表示摄像头 2表示从相册获取
           (typeid==1)?navigator.camera.PictureSourceType.CAMERA:navigator.camera.PictureSourceType.PHOTOLIBRARY  }
                                        );

        }

        function uploadPhoto(imageURI) {
   $("#uploadshowtext").text("正在上传......");
            var options = new FileUploadOptions();
            options.fileKey="file";
   //alert(imageURI.fullPath);
            options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);//安卓的地址是 context://scard/dicm/121/234  这里无文件扩展名
     //options.fileName=imageURI;
            //options.mimeType="image/jpeg";
   options.mimeType="multipart/form-data";//这两个参数修改了，后台就跟普通表单页面post上传一样 enctype="multipart/form-data"

   //options.mimeType="application/octet-stream";
   options.chunkedMode = false;

            var params = new Object();
            params.pid = kget("pid");
            params.feeid = feeid;
            options.params = params;

            var ft = new FileTransfer();
            ft.upload(imageURI, "http://server.com/uploadshow.asp?action=upload", win, fail, options);
        }

        function win(r) {
   //alert(JSON.parse(r.response).err);
   
            //alert("Code = " + r.responseCode);
            alert("上传成功");
   
           // alert("Sent = " + r.bytesSent);
        }
