What is the difference between a get commit and a post submission?
1,
Get commits, and the submitted information is displayed in the Address bar.
Post submission, the submitted information is not displayed in the Address bar.
2,
Get commits are not secure for sensitive data information.
Post submission, security for sensitive information.
3,
Get commits, not for big data, because the address bar storage volume is limited.
Post submission, you can submit large volumes of data.
4,
Get commits, encapsulating the information in the request line of the request message.
Post submission, encapsulating the information in the request body.
A difference in the service side.
If you submit Chinese to the Tomcat server, the server will decode with iso8859-1 by default, and it will appear garbled.
The code can be encoded by iso8859-1, and then decoded with the specified Chinese code table.
This approach is valid for both get and post submissions.
324
However, for the post submission method submitted in Chinese, there is another solution is to directly use the server side of an object
The Setcharacterencoding method of the Request object directly sets the specified Chinese code table so that the Chinese data can be parsed out
To.
This method decodes only the data in the request body.
Summary: Form submission, we recommend the use of post.
Three ways to interact with the server:
1, enter the URL address in the Address bar. Get
2, hyperlinks. Get
3, form. Get and Post
If an enhanced check is performed on the client (as long as there is a component content error, it is not possible to continue the commit, only the full pair can be committed)
Q, does the server need to verify after receiving the data?
Answer: Need, for security.
If the server does an enhanced checksum, does the client still need to verify?
A: need, because to improve the user's Internet experience, reduce the pressure on the server side.
