我想使用loopback扩展我的api。我已阅读文档
'use strict';
module.exports = function(Meetups,pusher) {
Meetups.status = function(cb) {
var currentDate = new Date();
var currentHour = currentDate.getHours();
var OPEN_HOUR = 6;
var CLOSE_HOUR = 20;
console.log('Current hour is %d', currentHour);
var response;
if (currentHour >= OPEN_HOUR && currentHour < CLOSE_HOUR) {
response = 'We are open yeah!!! for business.';
} else {
response = 'Sorry, we are closed. Open daily from 6am to 8pm.';
}
cb(null, response);
};
Meetups.remoteMethod(
'status', {
http: {
path: '/status',
verb: 'get'
},
returns: {
arg: 'status',
type: 'string'
}
}
);
Meetups.pusher = function(cb) {
if (2>1) {
response = 'sending something';
} else {
response = 'mont blanc';
}
cb(null, response);
};
Meetups.remoteMethod(
'pusher', {
http: {
path: '/pusher',
verb: 'get'
},
returns: {
arg: 'pusher',
type: 'string'
}
}
);
};
首先,我添加/状态路线,它工作正常。但是,当我试图添加/推动。它只是没有用。我收到了错误

我很确定,这是一个非常小的错误。我是loopback的初学者,并试图在我的项目中实现loopback。
答案 0 :(得分:1)
在示例中,他们将响应定义为该远程方法的局部变量,但事实并非如此。其次,(Meetups,pusher)你不需要在这里输出推杆。您正在添加到Meetups。
答案 1 :(得分:0)
您必须在Pusher远程方法中声明响应。 不声明响应的另一种方法是,仅返回值。
示例:
Meetups.pusher = function(cb) {
if (2>1) {
return 'sending something';
} else {
return 'mont blanc';
}
};
答案 2 :(得分:0)
定义变量并返回变量,或者您可以直接在if和else中调用cb
Meetups.pusher = function(cb) {
if (2>1) {
cb(null,'sending something');
} else {
cb(null, 'mont blanc');
}
};
