使用Phonegap将图片发送到服务器

Question

我想将图片发送到我的服务器。这是我的代码如下。我想为每张照片发送参数。我的问题是，如果我更改以下行fileSystem.root.getFile ("readme.txt",...，则fileSystem.root.getFile ("/ mnt / sdcard / Byza / readme.txt",...代码将无效。以及如何使用文件

发送参数

function test()
        {
            //window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFileSystemSuccess, fail);
        window.requestFileSystem(LocalFileSystem.PERSISTENT, 0,
                function(fileSystem)//On success find the file, we called to this Function.
                {
                   fileSystem.root.getFile("readme.txt", {create: false, exclusive: false}, 
                                           function(fileEntry)
                                           {
