Ionic HTTP POST - 500内部错误

时间：2016-03-16 18:55:20

标签： node.js rest heroku ionic-framework

我使用HTTP Post发布到我的Heroku服务器。当我把变量直接放在这样的服务器中时（我使用Postman）：

var user = "Mélanie",
name = "Sortie au musée",
tag = "servertest";

它的工作，但当我使用（点击离子按钮）时：

var user = req.body.user,
name = req.body.name,
tag = req.body.tag;

我有内部错误500 ...

我的控制器：

var SERVER_SIDE_URL = "https://myapp.herokuapp.com";
var pushUrl = SERVER_SIDE_URL + "/cancelpush";

$scope.canceled = function() {
    $http.post(pushUrl, {
        params: {
            user: "Mélanie",
            name: "Sortie à la salle",
            tag: "servertest"
        }
    }).success(function(data) {
        console.log("Success bro !" + data)
    }).error(function(data) {
        alert("ERROR" + data);
    });
};

我的服务器：

app.post('/cancelpush', function(req, res) {
  var user = req.body.user,
    name = req.body.name,
    tag = req.body.tag;

  var sendNotification = function(data) {
    var headers = {
      "Content-Type": "application/json",
      "Authorization": "Basic MyKey(Secret)"
    };

    var options = {
      host: "onesignal.com",
      port: 443,
      path: "/api/v1/notifications",
      method: "POST",
      headers: headers
    };

    var https = require('https');
    var req = https.request(options, function(res) {
      res.on('data', function(data) {
        console.log("Response:");
        console.log(JSON.parse(data));
      });
    });

    req.on('error', function(e) {
      console.log("ERROR:");
      console.log(e);
    });

    req.write(JSON.stringify(data));
    req.end();
  };

  var message = {
    app_id: "myappidwithnumbers(Secret)",
    contents: {
      "en": user + " not come " + name + " ! why ... "
    },
    tags: [{
      "key": tag,
      "relation": "=>",
      "value": tag
    }]
  };

  sendNotification(message);
});

请帮助我......谢谢！

编辑（问题解决，由于幻觉）：

错误的发生是因为未定义用户：

使用此服务器JS，它可以工作：

// init instances

var qs = require('querystring');
var request = require('request');
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var https = require('https');

// var stripe     = require("stripe")(STRIPE_API_SECRET_KEY);

var app = express();
var router = express.Router();
var port = process.env.PORT || 9311;

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
    extended: false
}));

// Cross Domain Origin Setup
var allowCrossDomain = function(req, res, next) {
    res.header('Access-Control-Allow-Origin', '*');
    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
    res.header('Access-Control-Allow-Headers', 'Content-Type, Authorization, Content-Length, X-Requested-With');

    // intercept OPTIONS method
    if ('OPTIONS' == req.method) {
        res.send(200);
    } else {
        next();
    }
};
app.use(allowCrossDomain);
app.use(function(req, res, next) {
    res.setHeader('Access-Control-Allow-Origin', '*');
    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
    res.setHeader('Access-Control-Allow-Credentials', true);
    next();
});

router.get('/', function(req, res) {
    res.json({
        message: 'hola ! welcome to our triple problem last api!'
    });
});


var url = 'http://requestb.in/wf21lpwf'
request(url, function(error, response, body) {
    if (!error) {
        console.log(body);
    }
});

app.post('/cancelpush', function(req, res) {
    // console.log(req);
    // console.log(res);

    var user = req.body.user;
    var name = req.body.name;
    var tag = req.body.tag;


    console.log(require('util').inspect(req.body.user));

    // var user = "Mélanie",
    //   name = "Sortie au musée",
    //   tag = "servertest";

    var sendNotification = function(data) {
        var headers = {
            "Content-Type": "application/json",
            "Authorization": "Basic MmNkNjc0YtYTcwODZmN2Y4MTYz"
        };

        var options = {
            host: "onesignal.com",
            port: 443,
            path: "/api/v1/notifications",
            method: "POST",
            headers: headers
        };

        var https = require('https');
        var req = https.request(options, function(res) {
            res.on('data', function(data) {
                console.log("Response:");
                console.log(JSON.parse(data));
            });
        });

        req.on('error', function(e) {
            console.log("ERROR:");
            console.log(e);
        });

        req.write(JSON.stringify(data));
        req.end();
    };

    var message = {
        app_id: "2549a5d6-e4d3afd941d9",
        contents: {
            "en": user + " notification " + name + " ! "
        },
        tags: [{
            "key": tag,
            "relation": "=>",
            "value": tag
        }]
    };

    console.log(require('util').inspect(message));

    sendNotification(message);

});


app.use(bodyParser.urlencoded({
    extended: true
}));
app.use(bodyParser());
app.use(bodyParser.json());
app.use('/api', router); // register our route
app.listen(port);

console.log('Magic happens on port ' + port);

我希望它可以帮助某人，感谢幻觉！

执行$http.post时，您的请求数据不需要包含在params对象中。在您的客户端代码中，尝试使用以下代码替换$scope.canceled：

$scope.canceled = function() {
    $http.post(pushUrl, {
        user: "Mélanie",
        name: "Sortie à la salle",
        tag: "servertest"
    }).success(function(data) {
        console.log("Success bro !" + data)
    }).error(function(data) {
        alert("ERROR" + data);
    });
}
