Question

我刚刚开始通过API管理工具构建我的第一个API，我遇到了一些问题，我希望你能帮助我。

我的主要目标是通过创建API链接到我上传的外部Javascript文件，让我的移动应用程序和Usergrid BAAS使用此API。到目前为止，我的经验是我的代码在我尝试的第一天工作，但完全相同的代码在第二天开始破解，这非常令人困惑。

PS-我将RemoteController.js文件作为节点类型上传

这是我非常简单的代码，我希望你帮助我发现导致错误的问题

测试链接：

=============我的server-usergrid.js代码===========

var argo = require('argo');
var express = require('express');
var usergrid = require('usergrid');
var fs = require('fs');
fs.readFileSync('./RemoteController.js','utf8');

var app = express();
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(app.router);

var proxy = argo()
    .target('https://api.usergrid.com')
    .build();

app.get('/hello', function(req, res) {
    res.send('Hello from Express2');
});


app.get('/helloworld', function(req, res) {
  res.setHeader("Access-Control-Allow-Origin","*");
  RemoteController.helloWorld(req, res);
});

app.all('*', proxy.run);
app.listen(3000);

=============我的RemoteController.js代码===========

function RemoteController() {
}

var client = new usergrid.client({
    orgName:'myOrg',
    appName:'sandbox',
    logging: true, //optional - turn on logging, off by default
    buildCurl: true
});

// test of helloworld
RemoteController.helloWorld = function(req, res) { 
        res.send('RemoteController inside helloWorld');
};

=============调用RemoteController.helloWorld时得到的错误===========

每个节点模块（文件〜=模块）都有自己的上下文。您可以从该上下文中导出变量，并将它们放入您的上下文中。

试试这个：

=============我的server-usergrid.js代码===========

var argo = require('argo');
var express = require('express');
var RemoteController = require('./RemoteController');

var app = express();
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(app.router);

var proxy = argo()
    .target('https://api.usergrid.com')
    .build();

app.get('/hello', function(req, res) {
    res.send('Hello from Express2');
});


app.get('/helloworld', function(req, res) {
  res.setHeader("Access-Control-Allow-Origin","*");
  RemoteController.helloWorld(req, res);
});

app.all('*', proxy.run);
app.listen(3000);

=============我的RemoteController.js代码===========

var usergrid = require('usergrid');

function RemoteController() {
}

var client = new usergrid.client({
    orgName:'myOrg',
    appName:'sandbox',
    logging: true, //optional - turn on logging, off by default
    buildCurl: true
});

// test of helloworld
RemoteController.helloWorld = function(req, res) { 
        res.send('RemoteController inside helloWorld');
};

module.exports = RemoteController;

Apigee API和Node.js需要新鲜的眼睛
