initCreatingDynamicConnectRequest

Dynamically generate a DID-Connect-Request Message and initiate a WebSocket connection

function setQrDataCallback(peerDID: string): void {
    console.log("set QR Data Callback", peerDID);
}

function setDIDAuthCallback(peerDID: string): void {
    console.log("setDIDAuthCallback");
}

function setConnectedCallback(peerDID: string): void {
    setPeerDID(peerDID);
    console.log("peerDID", peerDID);
}

function setAuthFailedCallback(peerDID: string): void {
    console.log("setAuthFailedCallback");
}

const agent: websocket.InfraDIDCommAgent = new websocket.InfraDIDCommAgent(
    "https://ws-server.infrablockchain.net/",
    did,
    mnemonic,
    // The role can be either a holder or a verifier
    "HOLDER",
);

const context = new messages.Context("pet-i", "connect");
const timeoutSeconds = 30;

agent.setDIDConnectedCallback(setConnectedCallback);
agent.setDIDAuthCallback(setDIDAuthCallback);
agent.setDIDAuthFailedCallback(setAuthFailedCallback);
agent.initCreatingDynamicConnectRequest(context, timeoutSeconds, setQrDataCallback);

initReceivingConnectRequest

Start a WebSocket connection upon receiving a DID-Connect-Request Message from a peer.

function setDIDAuthCallback(peerDID: string): void {
    console.log("setDIDAuthCallback");
}

function setConnectedCallback(peerDID: string): void {
    setPeerDID(peerDID);
    console.log("peerDID", peerDID);
}

function setAuthFailedCallback(peerDID: string): void {
    console.log("setAuthFailedCallback");
}

const agent: websocket.InfraDIDCommAgent = new websocket.InfraDIDCommAgent(
    "https://ws-server.infrablockchain.net/",
    did,
    mnemonic,
    // The role can be either a holder or a verifier
    "HOLDER",
);

agent.setDIDConnectedCallback(setConnectedCallback);
agent.setDIDAuthCallback(setDIDAuthCallback);
agent.setDIDAuthFailedCallback(setAuthFailedCallback);
agent.initReceivingConnectRequest(encoded);
