Node.js syntax error "unexpected token" on "exports."
提问by Saumya Tripathi
I have been trying to learn node.js. I am trying to create a simple node.js web api and a html-javascript front end to login using Facebook auth and store Facebook id in Mongodb.
我一直在努力学习 node.js。我正在尝试创建一个简单的 node.js web api 和一个 html-javascript 前端来使用 Facebook auth 登录并将 Facebook id 存储在 Mongodb 中。
I was able to do it by following tutorials available online.
我能够按照在线提供的教程来做到这一点。
Now I want to segregate the code into multiple files but when I try to create a route "user" and expose functions via exports. I am getting the following error.
现在我想将代码分成多个文件，但是当我尝试创建路由“用户”并通过导出公开功能时。我收到以下错误。
module.exports.userLogin = function(req,res){
^ SyntaxError: Unexpected token .

EDIT#1
编辑#1
module.exports.userLogin = function(req,res){
graph.setAccessToken(req.session.fb.access_token);
graph.get("/me", function(err, data) {
if(err){
console.log('Error obtaining data.');
return;
}
console.log(data);
}
}
EDIT # 2
编辑＃2
var mongo = require('mongodb'),
graph = require('fbgraph');
exports.userLogin = function(req,res){
graph.setAccessToken(req.session.fb.access_token);
graph.get("/me", function(err, data) {
if(err){
console.log('Error obtaining data.');
return;
}
console.log(data);
}
}
This is all I have in user route.
Actually, I was making a real silly mistake, I left a comma in front of graph = require('fbgraph')instead of semi colon.
After fixing this syntax error, I am getting this error.
这就是我在用户路由中的全部内容。实际上，我犯了一个非常愚蠢的错误，我在前面留下了逗号 graph = require('fbgraph')而不是分号。修复此语法错误后，我收到此错误。

You have a typo here:
你这里有一个错字：
graph.get("/me", function(err, data) {
if(err){
console.log('Error obtaining data.');
return;
}
console.log(data);
}
It should be:
它应该是：
graph.get("/me", function(err, data) {
if(err){
console.log('Error obtaining data.');
return;
}
console.log(data);
}); /* Note the added parenthesis here */
Also use exports.userLogininstead of module.exports.userLogin
也使用exports.userLogin代替module.exports.userLogin
