Question

使用简单的例子

var server = http.createServer(function(req, res){
  var output = {message: "Hello World!"};
  var body = JSON.stringify(output);

  res.writeHead(200, {
    "Content-Type": "application/json",
    "Access-Control-Allow-Origin": "*"
  });
  res.end(body);
});

我可以返回json对象。我怎样才能从这样的请求中返回一些参数

url: http://localhost:8080/get/jhon
output: {"message": "Hello jhon"}

Answer 1

为request.url

添加检查器

基本上，使用您自己的代码作为示例：

var server = http.createServer(function(req, res){
  var output = {message: "Hello World!"};
  var body = JSON.stringify(output);
  res.writeHead(200, {
     "Content-Type": "application/json",
     "Access-Control-Allow-Origin": "*"      
  });
  //.split creates an array with strings from the given url
  //req.url -> gives everything that's right after the http://localhost:8080/ portion
  var requested = req.url.split("/");
  output.message = "Hello " + requested[2]; // 0 is empty, 1 is "get"
  res.end(output);
});

希望有所帮助。

您可以修改.htaccess文件以将URL解析为参数。请参阅此问题以获取示例：htaccess url as parameter

从url获取日期并返回json
