我正在使用科尔多瓦的移动应用程序。它有一个在.docx格式的应用程序教程,我需要从应用程序传递给设备,以便它可以打开。请问是否有更好的方法让我知道,但这里是我的。用户点击一个按钮来查看教程文档,然后在用户可以查看.docx文件的任何应用程序中打开该教程文档。它在Android上运行得很好,但在iOS上却没有,我不知道为什么。下载函数中出现FileTransferError,错误代码为3.在iOS上,但不在Android上。我已经搜索过,但我可以找到的所有内容都是从Web服务器下载的。任何人都可以告诉我为什么我在iOS上得到错误代码3,但不是Android?Cordova下载文件从应用程序到设备
这是被点击按钮查看教程被称为代码:
function downloadTutorial() {
var userAgent = navigator.userAgent || navigator.vendor || window.opera;
if (userAgent.indexOf("Android") > -1) {
window.resolveLocalFileSystemURL(cordova.file.externalDataDirectory, function (directoryEntry) {
directoryEntry.getFile("app-tutorial.docx", { create: true }, function (fileEntry) {
download(fileEntry, encodeURI(cordova.file.applicationDirectory + "www/docs/app-tutorial-en.docx"));
}, function(e1){
console.error(`get file failed`);
console.log(e1);
});
}, function(e) {
console.error(`write failed`);
console.log(e);
});
}
else if ((userAgent.indexOf("iPad") > -1 || userAgent.indexOf("iPhone") > -1 || userAgent.indexOf("iPod") > -1) && !window.MSStream) {
window.resolveLocalFileSystemURL(cordova.file.documentsDirectory, function (directoryEntry) {
console.log(directoryEntry);
directoryEntry.getFile("app-tutorial.docx", { create: true }, function (fileEntry) {
console.log(fileEntry);
download(fileEntry, encodeURI(cordova.file.applicationDirectory + "www/docs/app-tutorial-en.docx"));
}, function(e1){
console.error(`get file failed`);
console.log(e1);
});
}, function(e) {
console.error(`write failed`);
console.log(e);
});
}
}
这里是下载功能:
function download(fileEntry, uri) {
var fileTransfer = new FileTransfer();
var fileURL = fileEntry.toURL();
console.log(fileURL);
var options = new FileUploadOptions();
options.headers = { Connection: "close" };
fileTransfer.download(uri, encodeURI(fileURL), function (entry) {
console.log("Successful downloaded tutorial file.");
cordova.plugins.fileOpener2.open(
fileURL,
"application/vnd.openxmlformats-officedocument.wordprocessingml.document", {
error : function(e) {
console.error(`Error status: ${e.status} - Error message: ${e.message}`);
},
success : function() {
console.log('file opened successfully');
}
}
);
},
function (error) {
console.error(`file transfer error ${error}`); // a FileTransferError is logged here with the source, destination and error code 3
}, false, options);
}

closebuttoncaption仅适用于iOS。看到这里http://stackoverflow.com/questions/42235892/cordova-download-file-from-app-to-device?rq=1 – user3417479
是的,这是真的。我只在iOS设备上使用它。 –
