    This document describes how to quickly run the TRTC-API-Example for Electron.

    Prerequisites

    Directions

    

    Step 1. Create an application

    1. In the TRTC console, click Development Assistance > Demo Quick Run.
    2. Select New and enter an application name such as TestTRTC. If you have already created an application, select Existing.
    3. Add or edit tags according to your needs and click Create.
    
    
    explain
    An application name can contain up to 15 characters. Only digits, letters, Chinese characters, and underscores are allowed.
    Tags are used to identify and organize your Tencent Cloud resources. For example, an enterprise may have multiple business units, each of which has one or more TRTC applications. In this case, the enterprise can tag TRTC applications to mark out the unit information. Tags are optional and can be added or edited according to your actual business needs.
    

    Step 2. Download the SDK and TRTC-API-Example source code

    1. TRTC-API-Example source code
    git clone https://github.com/tencentyun/TRTCSDK
    cd Electron/TRTC-API-Example
    

    Step 3. Configure TRTC-API-Example project files

    1. Find and open Electron/TRTC-API-Example/assets/debug/gen-test-user-sig.js.
    2. Set parameters in gen-test-user-sig.js as follows:
    SDKAPPID: A placeholder by default. Set it to the actual `SDKAppID`.
    `SECRETKEY`: A placeholder by default. Set it to the actual secret key.
    
    
    
    notice
    The method for generating UserSig described in this document involves configuring SECRETKEY in 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 suitable only 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. Compile and run the demo

    npm install
    cd src/app/render/main-page
    npm install
    
    cd ../../..
    npm run start

    FAQs

    1. Only public and private keys can be obtained when I try to view the key. How do I get a key?

    TRTC SDK 6.6 (August 2019) and later versions use the new signature algorithm HMAC-SHA256. If your application was created before August 2019, you need to upgrade the signature algorithm to get a new key. Without upgrading, you can continue to use the old algorithm ECDSA-SHA256. After upgrading, you can switch between the new and old algorithms as needed.
    Upgrade/Switch:
    1. Log in to the TRTC console.
    2. Click Application Management on the left sidebar, find your application, and click Application Info.
    3. Select the Quick Start tab and, in Step 2: obtain the secret key to issue UserSig, click HMAC-SHA256.
    Upgrade
    Switch to the old algorithm ECDSA-SHA256:
    
    
    Switch to the new algorithm HMAC-SHA256:
    
    

    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, you can refer to Firewall Restrictions to troubleshoot the issue.
