如何向第三方API写入Node.js请求？

Question

有没有人有一个API响应的例子从一个http.request()发送回第三方回到我的clientSever并写出到客户端浏览器？

我一直卡在我确定的简单逻辑中.我正在使用快递阅读文档它似乎没有为此提供抽象.

谢谢

请注意,这里的答案有点过时了 - 你会得到一个弃用的警告.2013年的等价物可能是:

app.get('/log/goal', function(req, res){
  var options = {
    host : 'www.example.com',
    path : '/api/action/param1/value1/param2/value2',
    port : 80,
    method : 'GET'
  }

  var request = http.request(options, function(response){
    var body = ""
    response.on('data', function(data) {
      body += data;
    });
    response.on('end', function() {
      res.send(JSON.parse(body));
    });
  });
  request.on('error', function(e) {
    console.log('Problem with request: ' + e.message);
  });
  request.end();
});

如果你要编写很多这些,我也会推荐请求模块.从长远来看,它会为你节省大量的击键!

以下是在快速获取函数中访问外部API的快速示例:

app.get('/log/goal', function(req, res){
    //Setup your client
    var client = http.createClient(80, 'http://[put the base url to the api here]');
    //Setup the request by passing the parameters in the URL (REST API)
    var request = client.request('GET', '/api/action/param1/value1/param2/value2', {"host":"[put base url here again]"});


    request.addListener("response", function(response) { //Add listener to watch for the response
        var body = "";
        response.addListener("data", function(data) { //Add listener for the actual data
            body += data; //Append all data coming from api to the body variable
        });

        response.addListener("end", function() { //When the response ends, do what you will with the data
            var response = JSON.parse(body); //In this example, I am parsing a JSON response
        });
    });
    request.end();
    res.send(response); //Print the response to the screen
});

希望有所帮助!
