curl usage

For sending data with POST and PUT requests, these are common curl options:

• request type

  • -X POST
  • -X PUT

• content type header

• -H "Content-Type: application/x-www-form-urlencoded"

• -H "Content-Type: application/json"

• data

  • form urlencoded: -d "param1=value1&param2=value2" or -d @data.txt
  • json: -d '{"key1":"value1", "key2":"value2"}' or -d @data.json

 eg:

curl -X POST -H "Content-Type: application/json" -d '{"text":"airship","channel_id":"CL2UK298B","user_name":"xinguo"}' ip_addr

curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d "text=airship&channel_id=CL2UK298B&user_name=xinguo" ip_addr
