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。但后来我收到一个 EPIPE(破管)错误。如果我再次按下上传按钮，它就会起作用。
如何防止错误发生？

最佳答案
我也一直在努力解决随机的间歇性 HTTP 状态错误，并采用了一种使用 var 来存储重试状态的解决方法。然后，如果调用传输失败回调并重试上传功能最多 3 次(尽管它不需要超过 1 次重试)，我会增加此 var:
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，用户可以在上传前过滤照片。如果没有应用过滤器，上传总是成功的。如果用户尝试应用任何过滤器，上传将随机失败并显示错误代码 3。
(是的，我知道这个解决方案并不完全理想，但总比无法恢复的故障要好。)
