我正在使用PhoneGap在Android上从画廊上传图像,但我想做的是获取文件名及其扩展名,但我无法从imageuri中获得它,有人能告诉我如何找到吗?

imageURI
是content://media/external/images/media/876
,所以有没有一种方法可以使用这个imageURI
获取一个文件条目,并读取文件名和扩展名?function fileUpload(){
navigator.camera.getPicture(
uploadPhoto,
function(message) { alert('get picture failed'); },
{
quality : 50,
destinationType : navigator.camera.DestinationType.FILE_URI,
sourceType : navigator.camera.PictureSourceType.PHOTOLIBRARY
}
);
}
function uploadPhoto(imageURI) {
var options = new FileUploadOptions();
options.fileKey="uploaded_file";
alert(imageURI);
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
var params = new Object();
params.value1 = "test";
params.value2 = "param";
options.params = params;
var ft = new FileTransfer();
ft.upload(imageURI, encodeURI("http://www.mydomain.com/mobile_upload.php"), win, fail, options);
}
function win(r) {
alert("WIN" +r.response);
console.log("Code = " + r.responseCode);
console.log("Response = " + r.response);
console.log("Sent = " + r.bytesSent);
}
function fail(error) {
alert("error");
alert("An error has occurred: Code = " + error.code);
console.log("upload error source " + error.source);
console.log("upload error target " + error.target);
}
