Postman实现jwt发送请求

news 2025/10/30 10:00:05

// Pre-request script
// 使用 CryptoJS（Postman 通常内置这个）
const generateJWT = () => {const issuer = "example.com";const secret = "secret_key";console.log("Generating JWT with issuer:", issuer);// Headerconst header = {"alg": "HS256","typ": "JWT"};// Payloadconst payload = {"iss": issuer,"exp": Math.floor(Date.now() / 1000) + 3600,"iat": Math.floor(Date.now() / 1000),"sub": "postman-test","name": "test"};try {// 方法2A: 使用 CryptoJS（如果可用）const base64Header = btoa(JSON.stringify(header)).replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '');const base64Payload = btoa(JSON.stringify(payload)).replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '');const data = base64Header + "." + base64Payload;// 简单的HMAC-SHA256实现const signature = CryptoJS.HmacSHA256(data, secret);const base64Signature = CryptoJS.enc.Base64.stringify(signature).replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '');const token = data + "." + base64Signature;pm.environment.set("jwt_token", token);console.log("JWT生成成功:", token);return token;} catch (error) {console.log("CryptoJS方法失败:", error);// 方法2B: 使用纯JavaScript的简单实现（用于测试）const simpleToken = generateSimpleJWT(header, payload, secret);pm.environment.set("jwt_token", simpleToken);console.log("使用简单方法生成的JWT:", simpleToken);return simpleToken;}
};// 简单的JWT生成函数（用于测试）
function generateSimpleJWT(header, payload, secret) {const base64Header = btoa(JSON.stringify(header)).replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '');const base64Payload = btoa(JSON.stringify(payload)).replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '');// 注意：这是一个简化的签名，仅用于测试const fakeSignature = "test_signature_only_for_debugging";return base64Header + "." + base64Payload + "." + fakeSignature;
}// 生成JWT
generateJWT();
