Question

我正在尝试使用写入restify响应的readStream来管道文件的内容。但我无法设置全局响应Content-Type标头

这是我的代码看起来像

let restify = require('restify');
let router = require('./routes');

let server = restify.createServer({
    formatters: null,      
    log: null,                 
    spdy: null,            
    version: '0.0.1',      
    handleUpgrades: false  
});

server.listen(8080, function() {
    console.log('%s listening at %s', server.name, server.url);
});

//I think this is suppose to set the response header across the app but it is not
restify.defaultResponseHeaders = function(data) {
    this.header('Content-Type', 'application/json');
};


server.use(restify.acceptParser(server.acceptable));  
server.use(restify.authorizationParser());  
server.use(restify.CORS());                 
server.use(restify.dateParser());           
server.use(restify.queryParser());          
server.use(restify.gzipResponse());         
server.use(restify.bodyParser());           
server.use(restify.requestLogger());        
//server.use(restify.throttle());             
server.use(restify.conditionalRequest());   
server.use(restify.fullResponse());         
server.use(restify.bodyParser());           

//router
router(server);

我的路线动作如下所示

let fs = require('fs');

module.exports = function ecmaRoutes(server) {

    let PATH = '/sample/';
    server.get(function sampleV1(req, resp) {

    let path = 'sample.json';

    let rStream = fs.createReadStream(path);  
    rStream.pipe(resp);

});

};

无论出于何种原因，我的回复都没有将内容类型设置为application/json。我可以使用

手动在路线动作中完成

resp.header('Content-type', 'application/json');

但如果我必须为每条路线做这件事，那就太麻烦了。

我的路线行动是否存在根本性的错误？

您不需要为每条路线都这样做。只需在listen函数后添加：

尝试类似的东西：

server.use(function(req,res,next){
  res.setHeader('content-type','application/json')
 //   OR
  res.setHeaders({'content-type'}:'application/json'})

 next()
})

设置restify默认JSON响应
