                                 console.log("res:"+JSON.stringify(data));

to sum up:

Test 1: background + foreground running locally, IP port different from the same test results: res: { "date": 1560913652938, "name": "amdin", "age": "20"}

Test 2: Local preceding operation, the background into the cloud server Tencent, the test results: res: { "date": 1560913652938, "name": "amdin", "age": "20"}
