无法使用 Cordova FileTransfer 上传文件

Question

我正在尝试使用 FileTransfer Cordova 插件 (https://github.com/apache/cordova-plugin-file-transfer) 的上传方法上传文件。最后，我几乎复制了项目页面上提到的示例，但仍然没有成功——该方法触发了成功回调函数，但目标脚本没有接收到文件或任何参数。我的代码是：

调用函数：

var fleNme = TOP_APP_DIR + "/config/config.json";

fileAPI.readFile(fleNme, function (data) {
    console.log("File content: " + data); // just to meake sure the file exists and it contains some data

    fileAPI.uploadFile("http://posttestserver.com/post.php", fleNme, { par1: "test", par2: "test2" }, null, function (r) {
            console.log("Successful upload...");
            console.log(JSON.stringify(r));
    });
});

上传功能：

fileAPI.uploadFile = function (url, filePath, params, progressFunc, successCallback, failCallback, FStype) {
    if (typeof failCallback === "undefined" || failCallback === null)
        failCallback = fileAPI.defaultErrorCallback;

    // getFileEntry method is used for reading the file before call the upload method, so it's OK
    fileAPI.getFileEntry(filePath, function (fileEntry) {
        var fileURL = fileEntry.toURL();

        var options = new FileUploadOptions();
        options.fileKey = "file";
        options.fileName = fileURL.substr(fileURL.lastIndexOf('/') + 1);
        options.mimeType = "text/plain";
        options.httpMethod = "POST";

        if(typeof params === "undefined" || params === null)
            params = {};

        options.params = params;

        var ft = new FileTransfer();

        ft.upload(fileURL, encodeURI(url), successCallback, failCallback, options);
    }, failCallback,FStype,false);
};

我的控制台的输出是：

• 文件内容：{"version":9,"timeStamp":1480793843086,"language":"cs" ......
• 上传成功...
• {"response":"成功转储 0 个帖子变量。\n在http://www.posttestserver.com/data/2016/12/03/11.41.062096548295查看它\n帖子正文长度为 0 个字符。","re​​sponseCode":200,"objectId":"","bytesSent":522 }

我的目标是 Cordova CLI 6.1.1。我花了一整天的时间尝试不同的方法，但总是得到相同的结果。我在 3 种不同的 Android 设备上调试了代码——HTC 10、三星 Galaxy Tab SM-T320 和一些旧的 Prestigio 手机——结果相同。知道有什么问题吗？

我发现默认设置chunkedMode（即true）存在很多问题。切换到options.chunckedMode = false 应该可以解决问题。
