用Node.js中的JSON对象响应（将对象数组转换为JSON字符串）

用Node.js中的JSON对象响应（将对象/数组转换为JSON字符串）

在Express中使用res.json：

function random(response) {  console.log("response.json sets the appropriate header and performs JSON.stringify");  response.json({     anObject: { item1: "item1val", item2: "item2val" },     anArray: ["item1", "item2"],     another: "item"  });}

或者：

function random(response) {  console.log("Request handler random was called.");  response.writeHead(200, {"Content-Type": "application/json"});  var otherArray = ["item1", "item2"];  var otherObject = { item1: "item1val", item2: "item2val" };  var json = JSON.stringify({     anObject: otherObject,     anArray: otherArray,     another: "item"  });  response.end(json);}
