使用Phonegap文件AP​​I获取所有文件名 [英] Get all filenames using Phonegap file API

问题描述

我正在使用Phonegap文件上传将SVG文件上传到我的服务器。它工作正常。但我需要从iPad的绝对路径中取出所有的SVG文件，并将它们发送到我的服务器。我不知道如何获取所有的.svg文件使用Phonegap的文件API，以便我可以发送到服务器循环通过文件名。

I am using Phonegap file upload to upload SVG files to my server. It's working fine. But I need to take all SVG files from the iPad's absolute path and send them to my server. I don't know how to get all .svg files using Phonegap's file API, so that I can send to the server looping through file names. Please tell me how to do this.

我的文件上传代码是：

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
  window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
}
function gotFS(fileSystem) {
  fileSystem.root.getFile("image5_2.jpg.svg", {create: true, exclusive: false}, gotFileEntry, fail);
}
function gotFileEntry(fileEntry) {
  var localpath=fileEntry.fullPath;
  uploadPhoto(localpath);
}
function uploadPhoto(imageURI) {
  var options = new FileUploadOptions();
  var ft = new FileTransfer();
  ft.upload(imageURI, "http://192.168.1.54:8080/POC/fileUploader", win, fail, options);
}

推荐答案

a href =http://docs.phonegap.com/en/1.8.1/cordova_file_file.md.html#DirectoryReader> DirectoryReader ，并循环遍历查找.svg文件的所有条目。

You need to create a DirectoryReader from the root FileSystem and loop through all the entries looking for .svg files.

function gotFS(fileSystem) {
    var reader = fileSystem.root.createReader();
    reader.readEntries(gotList, fail);    
}

function gotList(entries) {
    var i;
    for (i=0; i<entries.length; i++) {
        if (entries[i].name.indexOf(".svg") != -1) {
            uploadPhoto(entries[i].fullPath);
        }
    }
}

对此代码的细微修改，但它应该让你开始。

You may have to make some minor edits to this code but it should get you started.
