Phonegap 3.0 FileTransfer下载不工作 [英] Phonegap 3.0 FileTransfer download not working

问题描述

我是这样下载一个多部分mime编码的图像到iOS：

I'm downloading a multi-part mime encoded image to iOS like this:

var ft = new FileTransfer();
url = encodeURI(url);

ft.download(url, path, function(fileEntry) {}, function(err) {});

path = "file://localhost/var/mobile/Applications/D702F059-A29F-4FF4-A165-D4A903DEDE7D/Documents/captured/2419747919.jpeg"

并得到以下错误：

body: "Could not create path to save downloaded file: The operation couldn’t be completed. (Cocoa error 513.)"
code: 1 (file not found)
http status: 200

这暗示一个无效的路径，但我看不到任何错误。我得到这样的路径：

This hints to an invalid path, but I can't see anything wrong with it. I get the path like this:

path = fs.root.toURL();

其他一切正常，文件可以存储在完全相同的路径通过拍照。只是不通过FileTransfer下载。

Everything else works fine and files can be stored in exactly the same path by taking photos. Just not via a FileTransfer download.

Phonegap 3.0中的任何想法或错误？感谢！

Any ideas or a bug in Phonegap 3.0? Thanks!

UPDATE - 解决方法

FileWriter可以运行， iOS和Android。示例代码：

FileWriter works and now even saves blobs on iOS and Android. Example code:

var xhr = new XMLHttpRequest();

xhr.open('GET', url, true);
xhr.responseType = 'arraybuffer';

xhr.onload = function() {
    var blob = new Blob([xhr.response], {type: 'image/jpeg'});

    // save via FileWriter
};

xhr.send();

推荐答案

我在iOS中发现了问题：

I found the problem in iOS:

路径：
path =file：//localhost/var/mobile/Applications/D702F059-A29F-4FF4-A165-D4A903DEDE7D/Documents/captured/2419747919.jpeg

The path: path = "file://localhost/var/mobile/Applications/D702F059-A29F-4FF4-A165-D4A903DEDE7D/Documents/captured/2419747919.jpeg"

无法使用，因为它是一个包含localhost的网址。

does not work because it is an URL with "localhost" in it.

从Cordova中的FileEntry，可以使用fullPath和toURL...在Android上，他们都可以写一个文件。
在iOS上只有fullPath工作... URL不能成功写入文件！

From FileEntry in Cordova one can get a string using "fullPath" and "toURL" ... on Android they work both to write a file. On iOS only the fullPath works ... the URL does not successfully write a file!
