如何使用curl来获得与使用Chrome完全相同的GET请求？ [英] How to use curl to get a GET request exactly same as using Chrome?

问题描述

我有一个Web api http://something.com/api ，我想使用GET获取响应正文。

这是我的命令：

  curl http://something.com/api 
  

当然，它会失败并给出错误消息。

当我使用Chrome并输入上述网址时，一切正常。但是我用Firefox做同样的事情，URL给了我同样的错误信息。我尝试对Chrome扩展程序DHC重复该操作，请求再次给出正确的响应。经过一些搜索，我相信curl选项-user-agent 会有所作为。将用户代理设置为Chrome的正确方法是什么？还是这不是重点，问题出在其他领域吗？非常感谢。

解决方案

如果需要在curl请求中设置用户标头字符串，则可以使用 -H 选项将用户代理设置为：

  curl -H User-代理：Mozilla / 5.0（Macintosh；英特尔Mac OS X 10_10_3）AppleWebKit / 537.36（KHTML，例如Gecko）Chrome / 44.0.2403.89 Safari / 537.36 http://stackoverflow.com/questions/28760694/how-to-use-卷曲获得与铬相同的请求

使用

您现在有了一个cURL请求，可以在终端中运行该请求，该请求将反映您的浏览器发出的请求。这是我对此页面的要求（删除了Cookie标头）：

  curl -H主机：stackoverflow。 com -H缓存控制：max-age = 0 -H接受：text / html，application / xhtml + xml，application / xml; q = 0.9，image / webp，* / *; q = 0.8 -H用户代理：Mozilla / 5.0（Macintosh； Intel Mac OS X 10_10_3）AppleWebKit / 537.36（KHTML，例如Gecko）Chrome / 44.0.2403.89 Safari / 537.36 -H HTTPS：1 -H DNT：1  -H引荐来源：https://www.google.com/ -H接受语言：zh-cn，en; q = 0.8，en-GB; q = 0.6，es; q = 0.4  If-Modified-Since：Thu，2015年7月23日20:31:28 GMT-压缩http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-请求与使用铬完全相同
  

I have a web api http://something.com/api and I want to use GET to get the response body.

This is my command:

curl "http://something.com/api"

Of course, it fails and gives an error message.

When I use Chrome and input the above url, everythings correct. However I do the same things with Firefox, the url gives me the same error message. I try to repeat the action with Chrome extension DHC, the request gives correct response again. After some searching, I believe that the curl option --user-agent makes a difference. What is the correct way to set the user agent to Chrome? Or this is not the point, the problem comes from other fields? Thank you very much.

解决方案

If you need to set the user header string in the curl request, you can use the -H option to set user agent like:

curl -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.89 Safari/537.36" http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome

Using a proxy tool like Charles Proxy really helps make short work of something like what you are asking. Here is what I do, using this SO page as an example (as of July 2015 using Charles version 3.10):

1. Get Charles Proxy running
2. Make web request using browser
3. Find desired request in Charles Proxy
4. Right click on request in Charles Proxy
5. Select 'Copy cURL Request'

You now have a cURL request you can run in a terminal that will mirror the request your browser made. Here is what my request to this page looked like (with the cookie header removed):

curl -H "Host: stackoverflow.com" -H "Cache-Control: max-age=0" -H "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8" -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.89 Safari/537.36" -H "HTTPS: 1" -H "DNT: 1" -H "Referer: https://www.google.com/" -H "Accept-Language: en-US,en;q=0.8,en-GB;q=0.6,es;q=0.4" -H "If-Modified-Since: Thu, 23 Jul 2015 20:31:28 GMT" --compressed http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome
