获取数据的节点 Restify 用例给出了 "ResourceNotFound"

Question

我刚开始使用 Nodejs。

我正在使用 Restify 从以下位置获取数据：http://api.geonames.org/citiesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&lang=de&username=demo'。

我的以下代码出现错误：{"code":"ResourceNotFound","message":"/ does not exist"}

var restify =require("restify");

var server = restify.createServer();

server.use(restify.acceptParser(server.acceptable));
server.use(restify.queryParser());
server.use(restify.bodyParser());

server.get('http://api.geonames.org/citiesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&lang=de&username=demo', function (req, res) {
    console.log(req.body);
    res.send(200,req.body);
});

server.listen(7000, function () {
    console.log('listening at 7000');
});

那是因为 Restify 用于创建 REST 端点，而不是使用它们。您应该查看 this SO post 以获取有关使用 API.

数据的帮助

例如使用以下内容创建 test.js：

var http = require('http');
var options = {
  host: 'api.geonames.org',
  path: '/citiesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&lang=de&username=demo'
};

var req = http.get(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));

  // Buffer the body entirely for processing as a whole.
  var bodyChunks = [];
  res.on('data', function(chunk) {
    // You can process streamed parts here...
    bodyChunks.push(chunk);
  }).on('end', function() {
    var body = Buffer.concat(bodyChunks);
    console.log('BODY: ' + body);
    // ...and/or process the entire body here.
  })
});

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

然后运行 node test.js.

我找到了我要找的东西。您可以使用 restify 客户端获取 JSON 数据：

这是我的解决方案：

var restify = require("restify");

 function getJSONDataFromUrl(){
    var query = "?north=44.1&south=-9.9&east=-22.4&west=55.2&lang=de&username=demo";
    var options = {};
    options.url = "http://api.geonames.org";
    options.type = options.type || "json";
    options.path = "/citiesJSON" + query;
    options.headers = {Accept: "application/json"};


    var client = restify.createClient(options);

    client.get(options, function(err, req, res, data) {
        if (err) {
            console.log(err);
            return;
        }
        client.close();
        console.log(JSON.stringify(data));

        return JSON.stringify(data);
    });
}

getJSONDataFromUrl();
