curl -X, --request <command>

-X, --request <command>

1. curl 默认的http请求方法是GET。

在没有指定请求方法的时候，默认使用GET方法。

指定了，将使用指定的方法，如下图指定了POST方法。

2. 通常情况下，你并不需要指定这个选项，他会通过其他命令推导出来。

使用--data发送数据，自动指定方法POST.--data的内容在Windows只能用双引号括起来，在Linux中可以使用单引号。

3. 使用这个选项来指定http的请求方法，他并不会改变curl命令的实际行为，仅仅只是改了请求方法。

与上面的命令相同，只是请求方法改成了GET

1. (HTTP) Specifies a custom request method to use when communicating with the HTTP server.
2. The specified request will be used instead of the method otherwise used (which defaults to GET).
3. Read the HTTP 1.1 specification for details and explanations. Common additional HTTP requests include PUT and DELETE, but related technologies like WebDAV offers PROPFIND, COPY, MOVE and more.
4. Normally you don't need this option. All sorts of GET, HEAD, POST and PUT requests are rather invoked by using dedicated command line options.
5. This option only changes the actual word used in the HTTP request, it does not alter the way curl behaves. So for example if you want to make a proper HEAD request, using -X HEAD will not suffice. You need to use the -I, --head option.
6. (FTP) Specifies a custom FTP command to use instead of LIST when doing file lists with FTP.
7. If this option is used several times, the last one will be used.
