Abstract: According to embodiments of the present disclosure, a method, apparatus, device and storage medium for managing traffic data of a client application is provided. The method described herein comprises: detecting a transmission of user data of a target user from the client application to a server; analyzing the traffic data of the transmission at different layers of the transmission based on types of the traffic data; and in accordance with a determination that the analysis indicates that the traffic data satisfies a data exchange constraint corresponding to the target user, transmitting the traffic data to a server in compliance with the data exchange constraint. In this way, by analyzing the traffic data at different layers of the transmission and restricting traffic data that does not satisfy the data exchange constraint, it is possible to effectively prevent user data from being transmitted to unauthorized servers via various types of traffic data.

Abstract: Embodiments of the present disclosure provide a method, apparatus, device and storage medium for function processing. The method comprises: loading a first core library in a preset application program, wherein the first core library injects a proxy connect function in the first core library to a second core library to perform centralized management of the invoking of a preset socket, the second core library including a preset connect function, the preset connect function being used to establish a connection with the preset socket; injecting a custom connect function to the second core library based on a preset injection method corresponding to the proxy connect function; in accordance with a determination that the preset application program invokes the preset connect function via the second core library, invoking the custom connect function instead to implement a custom logic so as to delegate the preset socket.

Abstract: Embodiments of the present disclosure disclose a method, apparatus, device, and storage medium for processing a network request. The method comprises: activating a domain name server proxy based on local socket service in a preset application; in accordance with a determination that the preset application invokes a preset connect function, acquiring the preset connect function and replacing a destination file path in the preset connect function with a target file path corresponding to the domain name server proxy to establish a connection between the preset application and the domain name server proxy, wherein the target file path is pre-written in the preset application; receiving via the domain name server proxy a network request from the preset application, and parsing a domain name of the network request, and determining a first processing way of the network request based on a result of the parsing of the domain name.
