Postman 用 Pre-Script 设置请求头


因为项目需要在请求头中放 MD5 签名, Insomnia 不支持, 只能重新用回 Postman. 记录一下步骤:

配置自定义请求头, 使用未定义的环境变量

可以请求 postman-echo.com/get 来测试

编辑 Pre-Script


var timestamp = Math.round((new Date()).getTime() / 1000),
    secret = pm.variables.get('secret'),
    appKey = pm.variables.get('app_id');
    
signature = CryptoJS.MD5(appKey + timestamp + secret).toString();

pm.variables.set('request_timestamp', Math.round((new Date()).getTime() / 1000));

pm.variables.set('request_signature', signature);

查看结果
