无法保存路径文件 [英] Cannot save file with path

问题描述

我正在使用httpModule调用保管箱rest服务来下载文本文件.当我将其下载到内部存储时，似乎很高兴，但是随后我无法使用默认应用程序打开文本文件.因此，现在我将下载位置指向外部存储，但是出现错误错误:无法保存路径为/storage/emulated/0/myNewDir的文件".我已经向清单添加了write_external_storage和read_external_storage权限.这是我的代码:

I am using the httpModule to call a dropbox rest service to download a text file. When I download it to internal storage it seems happy but then I cannot open the text file with the default app. So now I am pointing the download location to the external storage, but I am getting an error 'Error: Cannot save file with path: /storage/emulated/0/myNewDir'. I have added thee write_external_storage and read_external_storage permissions to the manifest. Here is my code:

HomePage.prototype.getFile = function() {
var filePath = fs.path.join(fs.knownFolders.currentApp().path, "myFile.txt");
storage.createDirectory("myNewDir");

httpModule.getFile({
    url: "https://content.dropboxapi.com/2/files/download",
    method: "POST",
    headers: { "Content-Type": "", 
               "Dropbox-API-Arg": JSON.stringify({"path": "/path/file"}), 
               "Authorization": "*****" },      
}, storage.buildAbsolutePath()+"/myNewDir").then(function (response) {
    console.log(JSON.stringify(response));          
}, function (e) {
    console.log("Error occurred " + e);
});}

推荐答案

您需要在getFile函数中指定文件名，如下所示:

You need to specify the file name in the getFile function, like this:

httpModule.getFile({
    url: "https://content.dropboxapi.com/2/files/download",
    method: "POST",
    headers: { "Content-Type": "", 
               "Dropbox-API-Arg": JSON.stringify({"path": "/path/file"}), 
               "Authorization": "*****" },      
}, storage.buildAbsolutePath()+"/myNewDir/myFile.txt").then(function (response) {
    console.log(JSON.stringify(response));          
}, function (e) {
    console.log("Error occurred " + e);
});}
