这是我正在使用的代码。它位于我的app.js文件中
app.all("/*", function (req, res, next) { res.header("Access-Control-Allow-Origin", req.headers.origin); res.header("Access-Control-Allow-Credentials",true); res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS'); res.header('Access-Control-Allow-Headers', 'Content-Type,Accept,X-Access-Token,X-Key,Authorization,X-Requested-With,Origin,Access-Control-Allow-Origin,Access-Control-Allow-Credentials'); if (req.method === 'OPTIONS') { res.status(200).end(); } else { next(); }});
