GET Method
- GET means that the form data is to be encoded (by a browser) into a URL and this is the default HTTP method
- GET is less secure compared to POST, because data sent is part of the URL and Easier to hack
- URL length is restricted in GET method
- Can be bookmarked and cached
- GET requests are re-executed, on back button or re-submit behavior
- GET requests are idempotent (unchanged). It can be executed more than once without any side effects.
- Example:
- http://www.test.com/hello?key1=value1&key2=value2
·
POST Method
- POST means that the form data is to appear within the message body of the HTTP request
- POST is secure as compared to GET and difficult to hack
- No restriction on length
- Cannot be bookmarked and cached
- The browser usually alerts the user that data will need to be re-submitted, on back button or re-submit behavior
- POST requests are non-idempotent. So you have to be very careful while using POST functionality.
