The method for generating UserSig described in this document involves configuring SECRETKEY in the client code. In this method, SECRETKEY may be easily decompiled and reversed, and if your key is disclosed, attackers can steal your Tencent Cloud traffic. Therefore, this method is only suitable for the local execution and debugging of TRTC-API-Example.
The best practice is to integrate the calculation code of UserSig into your server and provide an application-oriented API. When UserSig is needed, your application can send a request to your server for a dynamic UserSig. For more information, see How do I calculate UserSig during production?.
Step 4. Configure demo project files
1.Find and open GenerateTestUserSig.h or GenerateTestUserSig.swift.
SDKAPPID: `0` by default. Set it to the actual `SDKAppID`.
SECRETKEY: left empty by default. Set it to the actual key.
Step 5. Compile and run the demo
Open the TRTC-API-Example-OC.xcworkspace project in the source code directory with Xcode (11.0 or later) and compile and run the TRTC-API-Example project.
FAQs
1. The demo is running on two mobile phones, but why can't they display the images of each other?
Make sure that the two mobile phones use different UserID. With TRTC, you cannot use the same UserID on two devices simultaneously unless the SDKAppID is different.
2. What are the restrictions of the firewall?
The SDK uses the UDP protocol for audio/video transmission and therefore cannot be used in office networks that block UDP. If you encounter such a problem, refer to Firewall Restrictions to troubleshoot the issue.
