require range[0-) with contentLength(2281)错误导致的下载失败 #1133

Open gitByteFlow opened 5 years ago

gitByteFlow commented 5 years ago

下载失败:服务器返回文件大小没有问题

报错如下

taskqueue erro: require range[0-) with contentLength(2281), but the backend response contentLength is 4845656 on downloadId[-1215868937]-connectionIndex[-1], please ask your backend dev to fix such problem.

从日志来看，第一次 trail connection 获取到的文件大小为 4845656 ，但是在下载时，返回的大小又变成了 2281 ，所以抛出了这个错误。

最好能提供一个完成的下载日志，这样能更准确确定问题。

@rantianhua 如何找下载日志？

rantianhua commented 5 years ago

在 issue 模板里就有说明：

Before Issue

  1. Please search on the Issues
  2. Please search on the wiki
  3. Please set FileDownloadLog.NEED_LOG=true and review the Logcat output from main process and :filedownloader process ( pay attention to Warn and Error level logcat)

打开日志开关后，过滤 FileDownloader 就能获取到所有 FileDownloader 日志。为了更好的可视化，你还可以用 https://github.com/Jacksgong/okcat 获取日志。
