Cordova FileTransfer下载错误 [英] Cordova FileTransfer Download error

问题描述

我有一个简单的混合应用程序，应该使用cordova 2.3.0下载文件。从文档中：

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);

            }
    );
}

结果是错误3，Connection_Err，与http_status 401，资源myfile。 pdf在没有必需的http服务器上公开。

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.

我已尝试使用getFile（my）创建文件文件：//mnt/sdcard/myfile.pdf file.pdf，{create：true，exclusive：false}，success，fail）;或者只是将字符串设置为现有目录。在这两种情况下都不行。

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.

你能告诉你吗？我必须使用cordova 2.3.0。

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

更新：

我认为我的问题非常接近于这一个： PhoneTransfer在Phonegap代码401

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

我有Android API 17，cordova 2.3.0，我需要设置allow origin =*，但是我无法创建config.xml文件，由于某些原因它抛出错误。你有遇到这个问题吗？

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?

我创建了文件夹xml里面的res（没有一个），并在这样的文件夹内创建一个文件config.xml。 config.xml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>

当我运行应用程序时，我收到一个警告与此错误：初始化Cordova：类未找到

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

推荐答案

所有的代码是正确的，这是我的框架配置的一个问题：

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

这个项目有另一个项目作为图书馆依赖。该项目没有一个config.xml文件将网址列入白名单。图书馆项目已经！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> 

到rightconfig.xml cordova文件，它是在一个Library项目中，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.
