Cordova 3.4.0上的文件系统失败，“无法创建目标文件” [英] FileSystem on Cordova 3.4.0 fails "Could not create target file"

问题描述

我最近将iOS Cordova专案从2.7.0升级到3.4.0。

升级文件系统访问后断开。 （似乎在模拟器中工作吗？）

我收到一条错误消息，指出无法创建目标文件，我googled周围想到改变我的全路径到toURL（），但没有效果。

这里是我的下载代码

c $ c> window.requestFileSystem（
LocalFileSystem.PERSISTENT，0，

function onFileSystemSuccess（fileSystem）{
fileSystem.root.getFile（
dummy.html ，{
create：true，
exclusive：false
}，

函数gotFileEntry（fileEntry）{
var sPath = fileEntry.toURL .replace（dummy.html，）;
var fileTransfer = new FileTransfer（）;
fileEntry.remove（）;

fileTransfer.download bhttps://dl.dropbox.com/u/13253550/db02.xml，
sPath +database.xml，

函数（theFile）{
console.log（download complete：+ theFile.toURI（））;
showLink（theFile.toURI（））;
setTimeout（function（）{
checkConnection（）;
}，50）;
}，

function（error）{
console.log（download error source+ error.source）;
console.log（download error target+ error.target）;
console.log（upload error code：+ error.code）;
}）;
}，
fail）;
}，
fail）;

解决方案

我发现文件插件a href =https://github.com/apache/cordova-plugin-file/blob/dev/doc/index.md =nofollow>链接）和fileTransfer插件（链接）

进行原始问题中提到的更改后，我想知道文件插件部分是否正确，并开始查找我的fileTransfer代码和提供的示例之间的差异。

原来我没有在我的下载源url（doh）

上做encodeURI（），所以完整的工作代码：

  window.requestFileSystem（
 LocalFileSystem.PERSISTENT，0，
 
 function onFileSystemSuccess（fileSystem）{
 fileSystem.root.getFile（
dummy.html，{
 create：true，
 exclusive：false 
}，
 
 function gotFileEntry fileEntry）{
 var sPath = fileEntry.toURL（）。replace（dummy.html，）; 
 var fileTransfer = new FileTransfer（）; 
 fileEntry.remove（）; 
 var DBuri = encodeURI（https://dl.dropbox.com/u/13253550/db02.xml）; 
 fileTransfer.download（
 DBuri，
 sPath +database.xml，
 
 function（theFile）{
 console.log ：+ theFile.toURI（））; 
 showLink（theFile.toURI（））; 
 setTimeout（function（）{
 checkConnection（）; 
}，50）; 
}，
 
 function（error）{
 console.log（download error source+ error.source）; 
 console.log + error.target）; 
 console.log（upload error code：+ error.code）; 
}）; 
}，
 fail）; 
}，
 fail）; 
  

I recently upgraded my iOS Cordova project from 2.7.0 to 3.4.0.

After upgrading filesystem access is broken. (seems to work in the simulator though?)

I get an error message stating "Could not create target file", I googled around and thought to change my "fullpath" to "toURL()" but to no avail. I really don't know what to try next?

here's my download code

window.requestFileSystem(
LocalFileSystem.PERSISTENT, 0,

function onFileSystemSuccess(fileSystem) {
fileSystem.root.getFile(
    "dummy.html", {
    create: true,
    exclusive: false
},

function gotFileEntry(fileEntry) {
    var sPath = fileEntry.toURL().replace("dummy.html", "");
    var fileTransfer = new FileTransfer();
    fileEntry.remove();

    fileTransfer.download(
        "https://dl.dropbox.com/u/13253550/db02.xml",
    sPath + "database.xml",

    function (theFile) {
        console.log("download complete: " + theFile.toURI());
        showLink(theFile.toURI());
        setTimeout(function () {
            checkConnection();
        }, 50);
    },

    function (error) {
        console.log("download error source " + error.source);
        console.log("download error target " + error.target);
        console.log("upload error code: " + error.code);
    });
},
fail);
},
fail);

解决方案

I found the documentation for both the file plugin ( link) and the fileTransfer plugin ( link)

After making the change noted in the original question, I wondered if the file plugin part was OK and started looking for discrepancies between my fileTransfer code and the examples provided.

Turns out I wasn't doing encodeURI() on my download source url (doh)

so the complete, working code:

window.requestFileSystem(
LocalFileSystem.PERSISTENT, 0,

function onFileSystemSuccess(fileSystem) {
fileSystem.root.getFile(
"dummy.html", {
create: true,
exclusive: false
},

function gotFileEntry(fileEntry) {
var sPath = fileEntry.toURL().replace("dummy.html", "");
var fileTransfer = new FileTransfer();
fileEntry.remove();
var DBuri = encodeURI("https://dl.dropbox.com/u/13253550/db02.xml");
fileTransfer.download(
    DBuri,
sPath + "database.xml",

function (theFile) {
    console.log("download complete: " + theFile.toURI());
    showLink(theFile.toURI());
    setTimeout(function () {
        checkConnection();
    }, 50);
},

function (error) {
    console.log("download error source " + error.source);
    console.log("download error target " + error.target);
    console.log("upload error code: " + error.code);
});
},
fail);
},
fail);
