我有一个适用于 android 的 cordova 2.0 应用程序。我使用 FileTransfer 插件将一些数据加载到我的服务器。第一次执行上传，一切正常。但后来我收到 EPIPE（断管）错误。如果我只是再次按下上传按钮，它就可以工作。

如何防止错误？

我也一直在努力解决随机间歇性 HTTP 状态错误，并采用了一种解决方法，使用 var 来存储重试状态。然后，如果调用了传输失败回调，我会增加这个 var 并重试上传函数最多 3 次（尽管它不需要超过 1 次重试）：

var imageRetry = 0; // if upload errors, retry 3 times
...
// file transfer fail callback
function fail(error) {
    if(imageRetry < 3){
         imageRetry++;
         uploadPhoto(); // call upload function again
    }else{
        // normal failure handling
    }
}

注意：服务器被列入白名单，我也尝试禁用 chunkedMode，但没有成功。我也没有使用普通或自签名 SSL。就我而言，用户可以在上传之前过滤照片。如果未应用过滤器，则上传始终成功。如果用户尝试应用任何过滤器，则上传随机失败，错误代码为 3。

（是的，我知道这个解决方案并不完全理想，但它比未恢复的故障要好。）
