节点js发布不与邮递员工作

我正在尝试在AWS上为节点JS服务器创build一个服务器（不知道这是多么的相关），我正在用Postmantesting它。 出于某种原因，我的Hello Worldfunction，这只是一个GET完美，但我的POST创build用户不断给我这个错误：

TypeError: Cannot read property 'username' of undefined at app.get.params.QueueUrl (/home/ec2-user/Outfitr/Server/index.js:40:29) at Layer.handle [as handle_request] (/home/ec2-user/Outfitr/Server/node_modules/express/lib/router/layer.js:82:5) at next (/home/ec2-user/Outfitr/Server/node_modules/express/lib/router/route.js:110:13) at Route.dispatch (/home/ec2-user/Outfitr/Server/node_modules/express/lib/router/route.js:91:3) at Layer.handle [as handle_request] (/home/ec2-user/Outfitr/Server/node_modules/express/lib/router/layer.js:82:5) at /home/ec2-user/Outfitr/Server/node_modules/express/lib/router/index.js:267:22 at Function.proto.process_params (/home/ec2-user/Outfitr/Server/node_modules/express/lib/router/index.js:321:12) at next (/home/ec2-user/Outfitr/Server/node_modules/express/lib/router/index.js:261:10) at serveStatic (/home/ec2-user/Outfitr/Server/node_modules/express/node_modules/serve-static/index.js:59:14) at Layer.handle [as handle_request] (/home/ec2-user/Outfitr/Server/node_modules/express/lib/router/layer.js:82:5) 

这是我的代码：

 var express = require("express") var app = express(); var gm = require("gm"); var fs = require("fs"); var async = require("async"); var s3 = new AWS.S3(); // set the region for the AWS API requests AWS.config.region = 'us-west-2'; var DAO_QUEUE_URL = 'https://sqs.us-west-2.amazonaws.com/275333356355/DAO-Queue'; app.set('port', (process.env.PORT || 8080 )); app.use(express.static(__dirname + '/public')); app.get('/', function(request, response) { response.send('Hello World (Finally)'); }); app.post('/create_user', function( request, response) { process.stdout.write("WTF"); create_user( request.body.username, request.body.password, request.body.firstname, request.body.lastname, request.body.gender, request.body.latitude, request.body.longitude, request.body.description, request.body.city, request.body.state_province, request.body.country, request.body.email, request.body.phone_number); response.send('IT WORKED!'); }); function create_user( username, password, firstname, lastname, is_brand, gender, description, city, state_province, country, birthday) { messageBody = {"username":username, "password":password, "firstname": firstname, "lastname":lastname, "is_brand":is_brand, "gender":gender, "city":city, "state-province":state_province, "country":country, "birthday":birtyhday}; queueUrl = DAO_QUEUE_URL; sendSQSMessage( JSON.stringify(messageBody),queueUrl); } 

什么可能是错的？

Answer 1

确保你在邮递员中使用了x-www-form-urlencoded标签。 我已经倒了好几次了。

另外，确保你正在使用body-parser包。

 var express = require("express") var app = express(); var gm = require("gm"); var fs = require("fs"); var async = require("async"); var bodyParser = require('body-parser'); var s3 = new AWS.S3(); // set the region for the AWS API requests AWS.config.region = 'us-west-2'; var DAO_QUEUE_URL = 'https://sqs.us-west-2.amazonaws.com/275333356355/DAO-Queue'; // Add the middleware app.use(bodyParser.urlencoded({extended: true})); app.use(bodyParser.json()); app.set('port', (process.env.PORT || 8080 )); app.use(express.static(__dirname + '/public')); 

所以我认为你得到的错误是因为没有中间件为你设置一个req.body对象，bodyParser应该做的。
