curl -X, --request

-X, --request

1. curl 默认的http请求方法是GET。
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。
3. 使用这个选项来指定http的请求方法，其实没卵用，他并不会改变curl命令的实际行为，你指定了GET，它并不一定使用GET方法发送请求。

明天上代码。

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.
