Question

我试图在我的openshift服务器上使用socket.io运行我的聊天程序，但每当我尝试重新加载它给我的链接时，它只是继续说：＆＃34; 503服务错误＆＃34;。我已经设置了我的存储库正确并使用rhc客户端将我的ssh密钥输入openshift，但无济于事，我使用的是端口3000，我也尝试了端口80，但它们都没有工作。

这是我的服务器代码和我的package.json：

var express = require("express"),
    app = express(),
    http = require("http").Server(app),
    io = require("socket.io")(http),
         require("./index.js");

app.use(express.static("static"));

io.on("connection", function(socket) {
    console.log("a user connnected");
    socket.on("disconnect", function() {
        console.log("user disconnected");
    });

    socket.on("chat message", function(msg) {
        console.log("message " + msg);
        io.emit("chat message", {m: msg.m, u: msg.u});
    });
});


var port;

if(process.argv[2]) {port = process.argv[2]} else {port = 3000}

http.listen(port, function() {
    console.log("chat listening on port " + port + ".");
});

我的package.json：

  "name": "ChatterBox",
  "version": "1.0.0",
  "description": ".",
  "main": "index.js",
  "dependencies": {

Answer 1

请参阅NSDictionary *json = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:nil; // use an NSError if you want NSArray *scheduleDates = json[@"schedule"]; for (NSDictionary *dates in scheduleDates) { NSString *endDateString = dates[@"end_date"]; NSString *startDateString = dates[@"start_date"]; }环境变量（以及页面底部的示例用法）：https://developers.openshift.com/en/node-js-environment-variables.html

Answer 2

使用$ OPENSHIFT_REPO_DIR代替$ relative_path_from_repo_dir

Openshift不会运行nodejs应用程序
