CURL不适用于参数中带有大括号的URL

user-agent request curl web google-chrome

有些带括号的URL不适用于CURL,但适用于Chrome和Firefox。

例如,此URL: https://rdtrkr.com/mg.php?voluum_id=d51b17bc-c537-4f3e-9879-2e373341ae5a&widget_id={widget_id}&campaign_id={campaign_id}&teaser_id={teaser_id}&geo={geo}&img=guy18.jpg&txt=german&lp=de&click_price={click_price}&click_id={click_id}&{click_id} 在Chrome和firefox中都可以工作,但是当使用CURL调用时,会出现404错误。

curl  \
-H "User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.80 Safari/537.36" \
-v "https://rdtrkr.com/mg.php?voluum_id=d51b17bc-c537-4f3e-9879-2e373341ae5a&widget_id={widget_id}&campaign_id={campaign_id}&teaser_id={teaser_id}&geo={geo}&img=guy18.jpg&txt=german&lp=de&click_price={click_price}&click_id={click_id}&{click_id}"

< HTTP/2 404 
< server: nginx
< date: Thu, 13 Dec 2018 16:53:45 GMT
< content-type: text/html; charset=UTF-8
< content-length: 0

但使用“保留日志”模式下的chrome Developer工具,我有:

CURL接收404而不是302重定向。这是否与CURL可能是URL编码括号的事实有关?我不知道这里出了什么问题。

花括号是 unsafe in URLs

换言之,它会转变 { 到 %7B 和 } 到 &7D .

-d 相反 自从将请求更改为帖子,您还需要使用 -G 强制请求成为GET。

因此,与其这样做

curl "http://example.com?param1=xxx&param2=yyy"

你能行

curl "http://example.com" -G -d "param1=xxx&param2=yyy"

Accept-Language

curl -v "http://rdtrkr.com/mg.php" \
     -G -d "voluum_id=d51b17bc-c537-4f3e-9879-2e373341ae5a&widget_id={widget_id}&campaign_id={campaign_id}&teaser_id={teaser_id}&geo={geo}&img=guy18.jpg&txt=german&lp=de&click_price={click_price}&click_id={click_id}&{click_id}" \
     -H "Accept-Language: en-US,en;q=0.9,fr;q=0.8,ru;q=0.7,es;q=0.6"

使用此标志(从 man curl ):

-g/--globoff
              This  option  switches  off  the "URL globbing parser". When you set this option, you can
              specify URLs that contain the letters {}[] without having them being interpreted by  curl
              itself.  Note  that  these  letters  are not normal legal URL contents but they should be
              encoded according to the URI standard.
