The difference between 2.Get and POST request modes
Get is a form value passed through a URL, and the form value that is passed by post is implicit in the HTTP message, which is not visible in the URL.
Get request format for passing data by URL
The file name requested in the URL followed by "? ", and then add the message to be uploaded key and value values
Multiple sets of key-value pairs, with "&" between key-value pairs
The URL contains Chinese characters, special symbols, which need to be encoded.
Get passes the amount of data is limited, if you want to pass a large amount of data can not be used to get, to use post.
Get
Advantages: Easy to test, simple and clear
Cons: Less information, less security
Post
Advantages: Large amount of information, relatively high security
Cons: Test not very convenient
