RESTful testing with cURL

Restful 21 มิ.ย. 2012

POST data to a REST resource:
curl -i -H "Accept: application/json" -X POST -d "firstName=james" http://resturl/section/sub

i – show response headers
H – pass request headers to the resource
X – pass a HTTP method name
d – pass in parameters enclosed in quotes; multiple parameters are separated by ‘&’
The above command posts the first name “james” to the persons resource. Assuming the server creates a new person resource with first name of James, I also tell the server to return a json representation of the newly created resource.


PUT a resource:
curl -i -H "Accept: application/json" -X PUT -d "phone=1-800-999-9999" http://resturl/persons/person/1

This puts a phone number to the person resource created in the previous example.


GET a resource:
curl -i -H "Accept: application/json" http://resturl/persons/person/1

For GET requests, the -X GET option is optional.

curl -i -H "Accept: application/json" http://resturl/persons?zipcode=93031

You can pass in query parameters by appending it to the url.

curl -i -H "Accept: application/json" "http://resturl/persons?firstName=james&lastName=wallis"
The resource uri needs to be quoted if you pass in multiple query parameters separated by ‘&’. If you have spaces in the query values, you should encode them i.e. either use the ‘+’ symbol or %20 instead of the space.


DELETE a resource:

curl -i -H "Accept: application/json" -X DELETE http://resturl/persons/person/1
To delete a resource, supply DELETE as a -X option.

Using POST to PUT a resource:

curl -i -H "Accept: application/json" -H "X-HTTP-Method-Override: PUT" -X POST -d "phone=1-800-999-9999" http://resturl/persons/person/1

Some clients do not support PUT or it’s difficult to send in a PUT request. For these cases, you could POST the request with a request header of X-HTTP-Method-Override set to PUT. What this tells the server is that the intended request is a PUT.
Most web servers (or you could code it) support the X-HTTP-Method-Override and convert the request method to the intended HTTP method (value of the X-HTTP-Method-Override)
This example puts a phone number (by POSTing) to the person resource identified by 1.


Using POST to DELETE a resource:

curl -i -H "Accept: application/json" -H "X-HTTP-Method-Override: DELETE" -X POST http://resturl/persons/person/1

Similar to the previous command, this example deletes the person resource identified by the above uri using the POST HTTP method but telling the server to override it with DELETE.
