heartbeat information struct is defined:
struct hb { int type; int length; unsigned char *data; };
Type indicates the heartbeat type and length indicates the data size. The content structure of the data field is as follows:
The Type field occupies one byte, the payload field occupies two bytes, and the rest is the specific content of payload

If the server response conforms to the above description, then the WebSocket connection is established and the status of the connection becomes "open state".2.5 Data Frames
The WebSocket protocol transmits data through serialized data frames. Fields such as opcode, payload length, payload data are defined in the packet protocol. It requires that the data frames that the client transm

The previous article explains some basic xss knowledge. This article continues to study. I mentioned some theoretical things in the previous article, and I soon forgot about it. After a brief review, we will talk about the xss classification: stored XSS, reflected XSS, and dom xss. I talked about a few simple payloads, which are just theoretical things. I will not continue to look at the theory in this article. I will first try to use
