wget破坏了内容的配置 [英] wget breaking with content-disposition

问题描述

我正在尝试从以下网站下载通过Content-Disposition：attachment发送的kml文件：

I am trying to download the kml file that is sent via Content-Disposition:attachment from the following website:

http://waterwatch.usgs.gov/index.php?m=real&w=kml&r=us&regions=ia

使用wget和curl命令：

Using wget and curl with the command:

wget --content-disposition http://waterwatch.usgs.gov/index.php?m=real&w=kml&r=us&regions=ia

和

curl -O -J -L http://waterwatch.usgs.gov/index.php?m=real&w=kml&r=us&regions=ia

但是，而不是保存文件作为发送器，它仅保存html内容，并且在发送结束时被卡住。最终返回值是：

However, instead of saving the file being transmitter, it saves only the html content and at the end of the transmission it gets stuck. The terminal return is:

$wget --content-disposition http://waterwatch.usgs.gov/index.php?m=real&w=kml&r=us&regions=ia

[2] 32261

他们变得很笨拙，我需要按Ctrl + C。
我得到的标头是

And them it got stuch and I need to press Ctrl+C. As the header I get is

HTTP/1.1 200 OK
Date: Sat, 14 May 2016 00:19:21 GMT
Content-Disposition: attachment; filename="real_ia.kml"
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: application/vnd.google-earth.kml+xml
X-Frame-Options: SAMEORIGIN

I会希望下载 real_ia.kml文件。
使用curl命令也会得到类似的结果。

I would expect to have the 'real_ia.kml' file downloaded. A similar result is given using curl command.

为什么会卡住并且仅下载HTML内容？

Why does it get stuck and downloads only the HTML content?

推荐答案

& 符号被解释为shell特殊字符，导致命令在后台运行（fork ）。因此，您应该转义或引用：

The & symbols are interpreted as the shell special character which causes a command to run in background(to fork). So you should escape or quote them:

curl -O -J -L 'http://waterwatch.usgs.gov/index.php?m=real&w=kml&r=us&regions=ia'

在上面的命令中，我们使用了完整引用。

In the command above we used full quoting.

输出的以下几行表示三行命令被派生到背景：

The following lines from your output mean that three commands are being forked to background:

[1] 32260
[2] 32261
[3] 32262

左边的数字（在括号中）是工作编号。您可以通过键入 fg N 将工作放在前台，其中 N 是工作编号。右边的数字是进程ID。

The numbers at the left (in brackets) are job numbers. You can bring a job to foreground by typing fg N, where N is the number of the job. The numbers at the right are process IDs.
