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。我的问题是内容类型标题。如果丢失，则服务器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。我想这是不错的默认行为，但我基本上希望它不发送未指定的标头。

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. 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 / . 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://domain.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

对要删除的标头使用 -H 标志，在之后没有任何内容：

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)

样本

-H 'User-Agent:'

这将使请求 无 $ c> User-Agent 标头（而不是发送带有空值的标头）

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