在本地运行解析服务器时出现此错误，但托管在 Heroku 上时没有出现此错误，是否有任何原因？状态：100 消息：XMLHttpRequest 失败：“无法连接到 Parse API”

我在本地安装并运行了 mongodb。我还有一个 .env 文件，其中包含APP_ID并MASTER_KEY在本地与 dotenv 一起被拉入。

这是我正在尝试做的一个简短示例...

var express = require('express');
var bodyParser = require('body-parser');
var dotenv  = require('dotenv').config({silent: true});
var ParseServer = require('parse-server').ParseServer;
var Parse = require('parse/node');

// Set up the parse server
var databaseUri = process.env.DATABASE_URI || process.env.MONGOLAB_URI;
var api = new ParseServer({
  databaseURI: databaseUri || 'mongodb://localhost:27017/dev',
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
  appId: process.env.APP_ID || 'myAppId',
  masterKey: process.env.MASTER_KEY || ''
});

// Set up express
var app = express();
app.use(express.static(__dirname + '/public'));
var mountPath = process.env.PARSE_MOUNT || '/parse';
app.use(mountPath, api);
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
  extended: true
}));

// Initialize parse so that I can use in my routes and controllers
Parse.initialize(process.env.APP_ID,'unused');
Parse.serverURL = process.env.SERVER_URI || 'http://locahost:1337/parse';

// Routes
app.get('/', function(req, res) {
  res.status(200).send('[form goes here that sends POST to "/sign-up"]');
});
app.post('/sign-up', function(req, res) {
  var user = new Parse.User();
  user.set("email", req.body.inputEmail);
  user.set("password", req.body.inputPassword);

  user.signUp(null, {
    success: function(user) {
      res.status(200).send('Signup Success!');
    },
    error: function(user, error) {
      res.status(200).send('Signup Failed');
    }
  });
});

var port = process.env.PORT || 1337;
app.listen(port);

该错误Unable to connect to the Parse API意味着 Parse sdk 无法连接到给定的 serverURL。在您的情况下，这似乎是一个错字：http://locahost:1337/parse应该是http://localhost:1337/parse？

您还应该删除var Parse = require('parse/node');和自定义初始化，因为 parse sdk 将在 Parse Server 中初始化，Parse然后将在全局范围内可用。查看自述文件中的使用示例。您的代码应如下所示：

var express = require('express');
var bodyParser = require('body-parser');
var dotenv  = require('dotenv').config({silent: true});
var ParseServer = require('parse-server').ParseServer;

// Set up the parse server
var databaseUri = process.env.DATABASE_URI || process.env.MONGOLAB_URI;
var api = new ParseServer({
  databaseURI: databaseUri || 'mongodb://localhost:27017/dev',
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
  appId: process.env.APP_ID || 'myAppId',
  masterKey: process.env.MASTER_KEY || '',
  serverURL: process.env.SERVER_URI || 'http://localhost:1337/parse'
});

// Set up express
var app = express();
app.use(express.static(__dirname + '/public'));
var mountPath = process.env.PARSE_MOUNT || '/parse';
app.use(mountPath, api);
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
  extended: true
}));

// Routes
app.post('/sign-up', function(req, res) {
  var user = new Parse.User(); // Parse available as a global variable
});

var port = process.env.PORT || 1337;
app.listen(port);
