Question

我正在开发基于Android的cordova 3.4.0，我的目标是下载一个文件并打开它。显然下载文件后，我很快就停留在下载位上，因为它是墓碑。

已安装插件，权限为：

<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />

我还有一个应用程序行：

android:largeHeap="true"

代码是：

    downloadFile: {

    run: function(uri, fileName, folderName) {

        var that = this;

        filePath = "";

        that.getFilesystem(
            function(fileSystem) {
                console.log("gotFS");

                if (APP.isAndroid()) {
                    that.getFolder(
                        fileSystem,
                        folderName,
                        function(folder) {
                            filePath = folder.toURL() + "\/" + fileName;
                            console.log("FILE PATH :::: " + filePath);
                            that.transferFile(uri, filePath);
                        }, function() {
                            console.log("failed to get folder");
                        }
                    );
                }
                else {
                    filePath = fileSystem.root.fullPath + "\/" + fileName;
                    that.transferFile(uri, filePath);
                }
            },
            function() {
                console.log("failed to get filesystem");
            }
        );
    },

    getFilesystem:function (success, fail) {
        window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
        window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, success, fail);
    },

    getFolder: function (fileSystem, folderName, success, fail) {
        fileSystem.root.getDirectory(folderName, {create: true, exclusive: false}, success, fail)
    },


    transferFile: function (uri, filePath) {
        var transfer = new FileTransfer();
        console.log("Trying to DL  : : " + encodeURI(uri) + " to " + filePath);
        /** **/
        transfer.download(
            encodeURI(uri),
            filePath,
            function (entry) {
                console.log("TRYING TO OPEN FILE ::: " + entry.toURL());
            },
            function (error) {
                console.log("download error source " + error.source);
                console.log("download error target " + error.target);
                console.log("upload error code" + error.code);
            }
        );
    }
},

.....

this.downloadFile.run(url, "file_name.pdf", "pdfs");

这似乎下载了文件，然后像这样的墓碑，偶尔到达成功回调。：

对于如何修复任何想法表示赞赏。

另一个原因可能是您使用的CrossWalk（替代浏览器插件）具有不同的Cookie API，FileTransfer插件不知道。修复https://github.com/gaochun/cordova-plugin-file-transfer/commit/0063249e279b99a0feb4601650fc3a4c9e8a8ed2?diff=split。
