有没有办法在phonegap中定义下载文件传输的超时时间。在Android设备上，如果我尝试下载无响应的URL，我会在8分钟后得到以下内容：

答案 0 :(得分：7)

他们似乎决定不将此作为一个选项来实现，因此只留下使用abort()和setTimeout()的唯一选择。

由于在下载/上传时设置任意时间限制似乎很天真，我会从fileTransfer.onProgress()重置超时

这样的事情：

var downloadTimer = setTimeout(function () {
    downloadTimerExceeded(fileTransfer);
}, 30000);

fileTransfer.onprogress = function (progressEvent) {
        if (downloadTimer) {
            clearTimeout(downloadTimer); //cancel the previous timer.
            downloadTimer = null;
        }
        downloadTimer = setTimeout(function () {
            downloadTimerExceeded(fileTransfer);
        }, 30000);
};

function downloadTimerExceeded(fileTransfer) {
    fileTransfer.abort();
}

如果他们在FileTransfer上有超时选项会好得多。

不，但这是功能请求https://issues.apache.org/jira/browse/CB-2394

答案 2 :(得分：0)

您是否尝试过使用chunkedMode选项？

答案 3 :(得分：0)

如功能请求注释中所述，这可以通过使用setTimeout（）

操作abord（）来完成。
