如何删除cURL发送的默认标头? [英] How can I remove default headers that cURL sends?

问题描述

默认情况下，Curl添加标头，例如 Content-type 和 User-agent .通常，这是一件好事，但当这些标头丢失时，我正在尝试测试服务器的工作.

Curl by default adds headers such as Content-type and User-agent. Normally that is a good thing but I'm trying to test what our server does when those headers are missing.

我的问题是 Content-type 标头.如果丢失，服务器将正确假定用户已发送JSON.但是，curl实际上会添加缺少的标题，并错误地假定我发布的内容是 application/x-www-form-urlencoded .它还发送/的Accept标头.

My problem is with the Content-type header. If it is missing, the server correctly assumes the user sent JSON. However, curl actually adds the missing header and incorrectly assumes that the content I am posting application/x-www-form-urlencoded. It also sends an Accept header of / .

我想这是很好的默认行为，但是我基本上希望它不发送我未指定的标头.有选择吗?

I suppose that is nice default behavior but I basically would like it to not send headers I did not specify. Is there an option for that?

curl -v -X POST 'https://example.com' -d '{...}'

> User-Agent: curl/7.37.1
> Host: domain.com
> Accept: */*
> Content-Length: 299
> Content-Type: application/x-www-form-urlencoded

推荐答案

在要删除的标头中使用 -H 标志，并且在:

Use -H flag with the header you want to remove and no content after the :

-H, --header LINE   Custom header to pass to server (H)

样品

-H 'User-Agent:'

这将使请求 没有 成为 User-Agent 标头(而不是发送带有空值的报头)

This will make the request without the User-Agent header (instead of sending it with an empty value)
