Question

我试图将reply.file（http://hapijs.com/api#replyfilepath-options）用于server.method（http://hapijs.com/api#servermethodname-fn-options），但它说我的next函数没有＆file ＃39; t Debug: hapi, internal, implementation, error TypeError: Uncaught error: Object function (err, result) { methodNext(err, result, null, { msec: timer.elapsed(), error: err }); } has no method 'file' at /Users/user/Work/Dev/export.js:37:12 at ChildProcess.<anonymous> (/Users/user/Work/Dev/node_modules/webshot/lib/webshot.js:221:9) at ChildProcess.emit (events.js:98:17) at Process.ChildProcess._handle.onexit (child_process.js:810:12)：

server.method('getExport', function(reqParams, queryParams, hostUri, next) {

  // ...
  next.file(filePath, {
    // Download as an attachment
    mode: 'attachment'
  });

});


Instance.server.route({
  method: 'GET',
  path: '/export',
  config: {
    handler: function(req, reply) {
      var uri = req.server.info.uri;

      server.methods.getExport(
        req.params,
        req.query,
        uri,
        reply
      );
    }
  }
});

我有以下内容：

有可能吗？

我正在使用hapi v6.9。

当你调用方法时，你必须传递一个回调方法。 https://github.com/hapijs/hapi/blob/83201d29bcc8c8edc46d9ecf4f1d51b7f3a3a4ff/lib/methods.js#L64

这是你的代码：

var hapi = require('hapi'),
    server = new hapi.Server('0.0.0.0', 5000);

server.method('getExport', function(reqParams, queryParams, hostUri, reply, next) {

  // ...
  reply.file('/tmp/test.js', {
    // Download as an attachment
    mode: 'attachment'
  });

  next();

});

server.route({
  method: 'GET',
  path: '/export',
  config: {
    handler: function(req, reply) {
      var uri = req.server.info.uri;

      server.methods.getExport(
        req.params,
        req.query,
        uri,
        reply,
        function () {
            console.log('ran');
        }
      );
    }
  }
});

server.start()

我强烈建议不要使用服务器方法，对于回复文件似乎有些过分。如果可能的话，我也强烈建议升级到最新版本的hapi。

是否可以在hapi中返回服务器方法的文件
