 无法访问互联网下载的用户，可以在互联网下载好，导入到内网。

2.使用

2.1用法

curl -X POST [options] [URL]

The -X option specifies which HTTP request method will be used when communicating with the remote server.

2.2 提交multipart/form-data数据

下边是文件上传的例子

# 文件上传
curl -X POST url  -F 'sbbh=A65DADBE166594FA70B622E29C45F935' -F file=@/data/zzzd/reg_record.mp3'

When the -F option is used, curl sends the data using the multipart/form-data Content-Type.

2.3 提交application/x-www-form-urlencoded数据

curl -X POST -d 'name=linuxize' -d 'email=linuxize@example.com' https://example.com/contact.php

If the -d option is used more than once you can merge the data using the & symbol

curl -X POST -d 'name=linuxize&email=linuxize@example.com' https://example.com/contact.php

 2.4 指定特定的Content-Type

To set a specific header or Content-Type use the -H option. The following command sets the POST request type to application/json and sends a JSON object

curl -X POST -H "Content-Type: application/json" -d '{"name": "linuxize", "email": "linuxize@example.com"}'  https://example/contact
