Webpage data transmission method

The invention belongs to the technical field of network security, and aims to provide a webpage data transmission method. In the implementation process, the to-be-submitted webpage data is encrypted through the client, safe transmission of the webpage data can be guaranteed, sensitive data leakage is prevented, the deployment cost is low, and the influence on an existing system is small; in addition, according to the embodiment, the anti-refreshing effect can be achieved by setting the computing power verification problem, specifically, after the client obtains the solution of the computing power verification problem through calculation, the encrypted sensitive data, the encrypted non-sensitive data and the solution of the computing power verification problem are constructed into webpage transmission request data, and the webpage transmission request data are transmitted to the client through the webpage transmission request data. According to the method and the device, the webpage transmission request data i
