Node.js 所有请求都是静态的 header
Node.js static header for all requests
我想为我的 node.js 服务器中的所有传入请求设置静态 header。
我目前的方法是为每个请求添加相同的 4 行 header(代码重复),我想解决这个问题,这是我想添加的 header 的一个示例:
app.post('/postJob', function(req,res){
console.log("request method :" + req.method);
// Website you wish to allow to connect
res.setHeader('Access-Control-Allow-Origin', '*');
// Request methods you wish to allow
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
// Request headers you wish to allow
res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
// Set to true if you need the website to include cookies in the requests sent
// to the API (e.g. in case you use sessions)
res.setHeader('Access-Control-Allow-Credentials', true);
res.setHeader('Content-Type', 'application/json');
有人知道如何定义它吗?
像这样
app.use(function(req, res, next) {
res.setHeader('Access-Control-Allow-Origin', '*');
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
res.setHeader('Access-Control-Allow-Credentials', true);
res.setHeader('Content-Type', 'application/json');
next();
});
