我用postman选择POST，输入网址及入参：
http://localhost:49449/ActionApi/UserInfo/CheckUserName?username=ZHANGSAN
结果得到的结果是这个,真是太奇怪了。
{
"version": {
"major": 1,
"minor": 1,
"build": -1,
"revision": -1,
"majorRevision": -1,
"minorRevision": -1
},
"content": {
"headers": [
{
"key": "Content-Type",
"value": [
"application/json; charset=utf-8"
]
}
]
},
"statusCode": 200,
"reasonPhrase": "OK",
"headers": [],
"requestMessage": null,
"isSuccessStatusCode": true
}
很有裨益。
