Question

我想为v17创建一个HapiJS插件，以将一些自定义标头附加到响应中，以用于cors，但这无关紧要。

const cors = {
    name: 'cors',
    version: '1.0.0',
    async register(server) {
        logger.debug('Initiating CORS internal plugin...');
        const { port } = server;
        originPort = port;

        server.ext('onPreResponse', async (request, h) => {

        return h
            .response()
            .header('Access-Control-Allow-Origin', resOrigin)
            .header('Access-Control-Allow-Methods', 'GET,POST,PUT,DELETE')
            .header('Access-Control-Allow-Headers', 'Content-Type, X-Requested-With, Authorization')
            .header('Access-Control-Allow-Credentials', 'true')
            .header('Access-Control-Max-Age', 1728000);
    });
},

};

这是我到目前为止所拥有的。我认为这是对的，因为我遇到错误。

我也尝试过：

  server.ext('onPreResponse', async (request, h) => {
        const { response } = request;

        response.header('Access-Control-Allow-Origin', resOrigin);
        response.header('Access-Control-Allow-Methods', 'GET,POST,PUT,DELETE');
        response.header('Access-Control-Allow-Headers', 'Content-Type, X-Requested-With, Authorization');
        response.header('Access-Control-Allow-Credentials', 'true');
        response.header('Access-Control-Max-Age', 1728000);

        return h.continue;
   });

这似乎在本地有效，但在测试过程中失败。

console.error node_modules/hapi/lib/core.js:126
    Debug: internal, implementation, error 
        TypeError: response.header is not a function
        at header (/home/node/app/src/lib/cors.js:47:22)
        at <anonymous>
        at process._tickDomainCallback (internal/process/next_tick.js:228:7)

如何在HapiJS v17中实现此目的？该版本中的API似乎已完全重构，并且在此版本的Hapi中几乎没有具体的示例。

谢谢！

当您返回Boom错误时，您的响应行为会更改。试试这个。

exports.plugin = {
    async register(server, options) {
        server.ext('onPreResponse', async (request, h) => {
            const {response} = request;

            if (response.isBoom) {
                response.output.headers['Access-Control-Allow-Credentials'] = 'true';
                response.output.headers['Access-Control-Allow-Methods'] = 'GET,POST,PUT,DELETE';
            } else {
                response.header('Access-Control-Allow-Credentials', 'true');
                response.header('Access-Control-Allow-Methods', 'GET,POST,PUT,DELETE');
            }

            return h.continue;
        });
    },
    name: 'cors'        
};

hapijs v17设置标头，然后在插件中发送响应
