从URL和返回JSON

Question

越来越日期使用简单的例子

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。如何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

添加一个检查为request.url

基本上，使用自己的代码为例：

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。看到这个问题的一个例子：htaccess url as parameter
