phonegap上传图片并传参（服务端是.NET
做的一般处理程序ashx）phonegap
上传图片传参 var
params = new Object(); params.value1
= "test"; params.value2
= "param"; options.params
= params;phonegap客户端（这里只写了上传的代码，调用机器API的就不写了） var
imageURI = document.getElementById(‘myImage‘).src; var
options = new FileUploadOptions(); options.fileKey
= "file"; var
imagefilename = Number(new Date()) + ".jpg"; options.fileName
= imagefilename; //options.fileName
= imageURI.substr(imageURI.lastIndexOf(‘/‘) + 1); options.mimeType
= "image/jpeg"; var
params = new Object(); params.value1
= "test";//此处设置要上传的参数 params.value2
= "param"; options.params
= params; var
url = "http://192.168.2.99/demo/upload.ashx?jsoncallback=?" var
ft = new FileTransfer(); ft.upload(imageURI,
url, win, fail, options, true);ashx
服务端using
System.Web;using
System.Data;using
System.Data.SqlClient;public
class upload : IHttpHandler { public
void ProcessRequest (HttpContext context) { context.Response.ContentType
= "text/plain"; string
callbackMethodName = context.Request.Params["jsoncallback"]; var

Value2 = context.Request["value2"];//这里就是获取得到phonegap上传的传的参数 if
(context.Request.Files.Count > 0) { //取到文件对象 HttpPostedFile
file = context.Request.Files[0]; //取得文件后缀名（带个点） string
ext = System.IO.Path.GetExtension(file.FileName); //判断上传文件的类型（jpeg），这里是根据文件头判断的，防止用户上传恶意假图 if
(file.ContentType == "image/jpeg" || file.ContentType == "image/pjpeg" || file.ContentType == "image/png" || file.ContentType == "image/gif") { //给文件取随及名 Random
ran = new Random(); string
