nodejs express测试

1.页面请求

app.get('/list_user', function (req, res) {
   console.log("/list_user GET 请求");
   //res.send('用户列表页面');
   res.send(app.get('env'));
});

成功！

2.get请求

app.get('/index_post', function (req, res) {
   res.render('index_post', { title: 'Express' });
});

app.get('/process_get', function (req, res) {
   // 输出 JSON 格式
   response = {
       first_name:req.query.first_name,
       last_name:req.query.last_name
   };
   console.log(response);
   res.end(JSON.stringify(response));
});

显示

{"first_name":"1","last_name":"1"}

3.post请求

app.post('/process_post', urlencodedParser, function (req, res) {
 
   // 输出 JSON 格式
   response = {
       first_name:req.body.first_name,
       last_name:req.body.last_name
   };
   console.log(response);
   res.end(JSON.stringify(response));
});

同上。

4.上传文件

app.get('/index_img', function (req, res) {
   res.render('index_img', { title: 'Express' });
});
app.get('/index.htm', function (req, res) {
   res.sendFile( __dirname + "/" + "index.htm" );
})
app.post('/file_upload', function (req, res) {
 
   console.log(req.files[0]);  // 上传的文件信息
 
   var des_file = __dirname + "/" + req.files[0].originalname;
   fs.readFile( req.files[0].path, function (err, data) {
        fs.writeFile(des_file, data, function (err) {
         if( err ){
              console.log( err );
         }else{
               response = {
                   message:'File uploaded successfully',
                   filename:req.files[0].originalname
              };
          }
          console.log( response );
          res.end( JSON.stringify( response ) );
       });
   });
});

{"message":"File uploaded successfully","filename":"QQ鎴浘20150729155015.png"}
