了解包含多个Content-Type标头的curl POST请求命令 [英] Understanding curl POST request command that contains multiple Content-Type headers
问题描述
以下curl命令:
curl -v -F 'json={"method":"update_video","params":{"video":{"id":"582984001","itemState":"INACTIVE"},"token":"jCoXH5OAMYQtXm1sg62KAF3ysG90YLagEECDAdlhg.."}}' https://api.somewebservice.com/services/post
产生此输出:
{"method":"update_video","params":{"video":{"id":"55269001","itemState":"INACTIVE"},"token":"jCoXH1sg62KAF3ysG90YLagEECTP16uOUSg_fDAdlhg.."}}' https://api.somewebservice.com/services/post

上面的输出中有两个"Content-Type"对象:
There are two 'Content-Type' objects in the above output:
> Content-Type: multipart/form-data;
和
< Content-Type: application/json;charset=UTF-8
根据 docs ，使用 -F 允许卷曲以多部分形式发送数据，但是 json = 是我在文档中找不到的.我假设它正在转换字典/字符串:
According to the docs, using -F allows curl to send data as a multi-part form, but then the json= is something I can't find in the docs. I'm assuming it's converting the dictionary/string:
{"method":"update_video","params":{"video":{"id":"582984001","itemState":"INACTIVE"},"token":"jCoXH5OAMYQtXm1sg62KAF3ysG90YLagEECDAdlhg.."}}
使用JSON?或更准确地说，是在POST请求中添加'Content-Type':'application/json'标头吗?那么，这本质上是具有两个不同标头的POST请求吗?
to JSON? Or more precisely, it's adding the 'Content-Type': 'application/json' header to the POST request? So is this essentially a POST request with two distinct headers?
推荐答案
第一个 Content-Type 标头是客户端 request 标头的一部分，第二个标头是客户端的 request 标头的一部分服务器的 response 标头中的一个.请求和响应由2个CRLF分隔.请求和响应都有各自的内容类型.
The first Content-Type header is part of the client's request header and the second one is part of the server's response header. The request and the response are separated by 2 CRLFs. Request and response each have their own Content-Types.
