wget下载后不会保持源文件格式

[Feng-Yong-Qi]

使用wget下载后的文件名称为：'select?code=95643'，并不是文件原格式。我需要将：'select?code=95643' 修改为源文件格式才可以。比如源文件是个aaa.jpg，但是我wget下来的文件名是：'select?code=95643'，我需要修改：mv 'select?code=95643' aaa.jpg 这样才可以

代码中所有的file_storage.get_file_response已经正确添加了Content-Dispositionheader，所以正常来说不会有问题（wget 尊重这个 Header，会重新设置正确的文件名）

问题更加复杂

在@share_api.get("/select/") 这里的定义中的路径定义是以斜杠结尾，fastapi 的默认行为是会发生一次重定向，即期待的行为是

curl https://share.lanol.cn/share/select?code=12345
# => 307 Temporary Redirect
curl https://share.lanol.cn/share/select/?code=12345

但是实际行为是

curl https://share.lanol.cn/share/select?code=12345
# => 307 Temporary Redirect
curl https://share.lanol.cn//share/select/?code=12345  # 出现了双斜杠，也就是说 wget 拿回来的是个 html 文件而不是附件，所以文件名会错误

这里重定向到错误 URL 的问题需要继续排查

curl 的结果如下

curl https://share.lanol.cn/share/select\?code\=xxxxx  -v

可以让 <点击复制wget命令> 按钮生成的wget命令携带一个-O参数指定保存文件名

代码中使用的filename*而不是常用的filename，需要在wget命令加下述选项：

wget --content-disposition --trust-server-names "https://share.lanol.cn/share/select?code=12345"
