android - 白名单文件传输问题

Question

我正在使用此代码通过 FileTransfer 插件将文件下载到 Android 设备

function filetransfer(download_link, fp) {
    alert(fp);
    var fileTransfer = new FileTransfer();
    // File download function with URL and local path
    fileTransfer.download(download_link, fp,
    function (entry) {
        alert("download complete: " + entry.fullPath);
    },
    function (error) {
    //Download abort errors or download failed errors
        alert("download error source " + error.source);
    //alert("download error target " + error.target);
    //alert("upload error code" + error.code);
    }
   );
}

传输失败。我检查了我的配置，该配置设置为接受所有域。我有项目 > res > xml > config.xml 与 <access origin="*"/>

为什么这不起作用？

如果您使用的是 cordova-android 版本 4.0，您将需要 whitelist plugin .随着 cordova cli 5.0 版本的发布，核心插件更新有一些重大变化。

Cordova Blog: Moving Plugins to NPM

We recently released cordova-plugin-whitelist and cordova-plugin-legacy-whitelist. We have revamped how whitelisting works starting with cordova-android@4.0.0. With this change, setting a Content-Security-Policy (CSP) is now supported. Network requests are blocked by default without cordova-plugin-whitelist, so install this plugin even to allow all requests, and even if you are using CSP.

还要注意插件 ID 随此迁移到 npm 的变化(例如 org.apache.cordova.file-transfer 到 cordova-plugin-file-transfer ) 这可能会在您升级时绊倒您。
