科尔多瓦文件传输下载错误 [英] Cordova FileTransfer Download error

问题描述

我有一个简单的应用程序混合动力应该与下载2.3.0科尔多瓦文件。从文档：

I have a simple hybrid app which should download files with cordova 2.3.0. From the documentation:

var filePath = someFullPath; //e.g. "file:///mnt/sdcard/myfile.pdf"
var uri = encodeURI("http://someurl.com/myfile.pdf");

var fileTransfer = new FileTransfer();

fileTransfer.download(
            uri,
            filePath,
            function(entry) {
                console.error("download complete: " + entry.fullPath);
            },
            function(error) {
                console.error("download error source " + error.source);
                console.error("download error target " + error.target);
                console.error("donwload error code " + error.code);
                console.error("http: "+error.http_status);

            }
    );
}

的结果是错误3，Connection_Err，与HTTP_STATUS 401，资源myfile.pdf是公开的，没有身份验证需要一个HTTP服务器上。

The outcome is error 3, Connection_Err, with http_status 401, the resource myfile.pdf is public on a http server with no auth required.

我曾经尝试都创建该文件的文件：//mnt/sdcard/myfile.pdf用的GetFile（我的file.pdf，{创建：真实，独家：假}，成功，失败）;或者只是设置一个字符串现有的目录。它并没有在这两种情况下工作。

I have tried both creating the file file://mnt/sdcard/myfile.pdf with getFile("my file.pdf", {create: true, exclusive: false}, success, fail); or just setting a string to an existing directory. It didn't work in both scenarios.

能否请您指教？我必须用科尔多瓦2.3.0。

Can you please advise? I have to use cordova 2.3.0.

更新：

我想我的问题是非常接近此一：文件传输中的PhoneGap code 401

I think my problem is very close to this one: FileTransfer in Phonegap code 401

我的Andr​​oid API 17，科尔多瓦2.3.0，我需要设置允许原点=*，但我不能创建config.xml文件，因为某些原因，它抛出的错误。你有没有遇到这个问题？

I have Android API 17, cordova 2.3.0, I need to set allow origin = "*", but I can't create the config.xml file, for some reasons it throws errors. Have you faced this problem?

我创建资源里面的文件夹XML（有没有一）和创建这样的文件夹中的文件config.xml中。 config.xml文件的内容是

I created the folder xml inside res (there wasn't one) and created a file config.xml inside such folder. The content of the config.xml is

 <access origin="*"></access>

当我运行应用程序，我得到这个错误警报：错误初始化科尔多瓦：找不到类

when I run the application I get an alert with this error: Error Initializing Cordova: Class not found

推荐答案

所有code是正确的，这是我的框架结构的问题：

All the code was correct, it was a problem with my configuration of the framework:

该项目还有另外一个项目作为库的依赖。这个项目没有一个config.xml文件，其中列入白名单的URL。库项目了！我只需要添加

this project had another project as library dependence. This project didn't have a config.xml file where to whitelist URLs. The library project had! I just needed to add the

<access origin="http://*.somedomain.com"></access> 

要正确的config.xml文件科尔多瓦，这是在一个库项目，而不是在主要项目本身。

to the "right" config.xml cordova file, which was in a Library project, not in the main project itself.
