//post请求的基本服务器 var http=require("http"); var jsonData=""; http.createServer((req,res)=>{ console.log(req); req.on("data",(chunk)=>{ jsonData+=chunk; }); req.on("end",()=>{ console.log("???"); console.log(jsonData); var reqObj=JSON.parse(jsonData); console.log(reqObj); var resObj={ message:"hello "+reqObj.name, question:"Are you "+reqObj.age+" age ?" }; res.writeHead(200); res.end(JSON.stringify(resObj)); }); console.log("??"); }).listen(8080); console.log("???"); var options={ host:"127.0.0.1", path:"/", port:"8080", method:"POST" }; var req=http.request(options,(response)=>{ console.log("????"); var responseData=""; response.on("data",(chunk)=>{ responseData+=chunk; }); response.on("end",()=>{ var dataObj=JSON.parse(responseData); console.log("Raw Response : "+responseData); console.log("Message : "+dataObj.message); console.log("Question : "+dataObj.question); }); console.log("?????"); }); req.write('{"name":"Soul","age":21}'); req.end(); console.log("????????");
