This morning I saw a summary of get/postArticleIn fact, this is a common problem during the interview.
Two data submission methods for Form
<Form ID = "form1"Method = "get"Runat = "server">
</Form>
<Form ID = "form1"Method = "Post"Runat = "server">
</Form>
Their differences in data reception are as follows:
Get method: request. querystring ["ID name"];
POST method: request. Form ["ID name"];
Alternatively, request. Params [""]; or request [""];
The summary is as follows:
1. Get is to get data from the server, and post is to send data to the server.
2. Get is to add the parameter data queue to the URL referred to by the Action attribute of the submission form. The values correspond to each field in the form one by one and can be seen in the URL. Post is implemented through HTTP
Post mechanism: place the fields in the form and their content in the HTML header and send them to the URL address referred to by the Action attribute. You cannot see this process.
3.
For the get method, the server uses request. querystring to obtain the value of the variable. For the POST method, the server uses request. Form to obtain the submitted data.
4. The data volume transmitted by get is small and cannot exceed 2 kb. The amount of data transmitted by post is large, which is generally not restricted by default.
5. Low get security and high post security. However, the execution efficiency is better than the POST method.
Suggestion:
1. The get method is more secure than the POST method. If it contains confidential information, we recommend that you use the post data submission method;
2. We recommend that you use the get Method for Data Query. When adding, modifying, or deleting data, we recommend that you use the POST method.
