This article introduces in detail the corresponding analysis and solution to how to deal with the pending status by stopping the call to the head interface through the Onvif protocol, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

When the camera device supports the head, the video structured security intelligent platform EasyNVR supports calling the head control of the camera through the onvif protocol. However, if the user name and password are incorrect, the call to stop the head control API will always be in pending status.

The pending status of the interface can be seen through the browser debugging interface, but no content has been returned.

After analyzing the backend interface, it is found that there is a problem with the logic in the StopPTZ method. The logic currently used is as follows:

Func StopPTZ (host, username, password, deviceUrl string) (err error) {if dll = = nil {err = fmt.Errorf ("onvif dll not init") return} ptz: = fmt.Sprintf ("stop ptz host [% s] username [% s] password [% s] deviceUrl [% s]", host, username, password DeviceUrl) global.OperationLogger.Info (ptz) _ host: = uintptr (unsafe.Pointer (syscall.StringBytePtr (host) _ username: = uintptr (unsafe.Pointer (syscall.StringBytePtr (username) _ password: = uintptr (unsafe.Pointer (syscall.StringBytePtr (password) _ deviceUrl: = uintptr (unsafe.Pointer (syscall.StringBytePtr (deviceUrl) I: = 1 for I
