json数据格式

JSON（JavaScript Object Notation, JS对象简谱）是一种轻量级的数据交换格式。它基于 ECMAScript（European Computer Manufacturers Association, 欧洲计算机协会制定的js规范）的一个子集，采用完全独立于编程语言的文本格式来存储和表示数据。简洁和清晰的层次结构使得 JSON 成为理想的数据交换语言。易于人阅读和编写，同时也易于机器解析和生成，并有效地提升网络传输效率。

JSON 语法

JSON是一个标记符的序列。这套标记符包含六个构造字符、字符串、数字和三个字面名。 JSON是一个序列化的对象或数组。

代码语言：javascript复制

{"state":true,"message":"成功访问","result":["苏洵","苏轼","苏辙","苏秦","苏代","苏厉"]}

这里写了个通用的格式，key:value类型。可以直接使用，我们为了练习，强行二次json序列化一下。

返回对象

代码语言：javascript复制

public class SUCCESS
{
    public SUCCESS(string message,object result) {
        this.state = true;
        this.message = message;
        this.result = result;
    }
    public Boolean state { get; set; }
    public string message { get; set; }
    public object result { get; set; }
}

Json序列化

代码语言：javascript复制

using Newtonsoft.Json;
[HttpGet]
public Object GetInfo()
{
    List<string> list = new List<string>() { "苏洵", "苏轼", "苏辙", "苏秦", "苏代", "苏厉" };
    return JsonConvert.SerializeObject(new SUCCESS("操作成功", list));
}

下面是返回结果

代码语言：javascript复制

"{"state":true,"message":"成功访问","result":["苏洵","苏轼","苏辙","苏秦","苏代","苏厉"]}"

反序列化:

使用JsonConvert.DeserializeObject(string)进行反序列化

代码语言：javascript复制

public object GetInfoApi() {
    HttpClient http = new HttpClient();
    Task<string> task = http.GetStringAsync("http://localhost:1246/api/Test/GetInfo");
    string result = task.Result;
    return JsonConvert.DeserializeObject(result);
}

如果未反序列化直接输出则是：

反序列化后：

可以看到对应的效果，不过我们不能使用这种带/的json数据，这类是无法正常解析的。

稍微大型一些json格式数据：

{ "code": 200, "message": "查询成功", "result": [ { "id": "1D19A58448C144CDA867B3BCE7265D07", "createDate": "2021-06-12T14:38:50.547", "nickName": "苏泽开", "introduce": "帅气的王润松同桌" }, { "id": "2CC74D39758641EB99AB0A6DCC59F5E5", "createDate": "2021-06-11T15:15:25.583", "nickName": "张宇婷", "introduce": "国士无双" }, { "id": "30F890AB477D4425ADE95773F95985F0", "createDate": "2021-06-11T15:16:51.4", "nickName": "张舒", "introduce": "迪士尼在逃公主，仙女啥样她啥样。" }, { "id": "5f42022a8bd347609defc4efd122aa5d", "createDate": "2021-09-28T14:19:18.71", "nickName": "曲弘扬", "introduce": "黑帮教父" }, { "id": "6A8746DCB76547BD9BB66597E7E06EF3", "createDate": "2021-06-11T15:12:39.32", "nickName": "王佳敏", "introduce": "当真是喜从天降，一生之中，从未听见过有四个字是这般好听的。" }, { "id": "86A3F5AAEBBA49768E6BE55E631B9A21", "createDate": "2021-06-11T15:16:22.947", "nickName": "张紫璇", "introduce": "峨眉绝世不可寻，能使花羞在上林。" }, { "id": "955D402234224263A91C28BFD93A24A4", "createDate": "2021-06-11T15:10:53.753", "nickName": "常子怡", "introduce": "北方有美人绝世而独立。一顾倾人城，再顾倾人国。" }, { "id": "9855E757E7664F7A81D10159FA4AA4B4", "createDate": "2021-06-11T15:08:44.89", "nickName": "黄珊", "introduce": "箫长琴短衣流黄" }, { "id": "9B924F52D9984ED89F0B503D884C86BE", "createDate": "2021-06-11T15:06:05.217", "nickName": "王浩博", "introduce": "人见人爱，花见花开，车见车载。" }, { "id": "d0dff2b742054077a4cf94907a25d168", "createDate": "2021-09-15T09:26:49.317", "nickName": "龙珠", "introduce": "笑若桃花三月开，清风徐徐醉颜来。" }, { "id": "D8936E94D3AE4313A7C4B2F469B417E5", "createDate": "2021-06-11T15:13:38", "nickName": "付伟佳", "introduce": "芙蓉不足佳人妆，水殿风来珠翠香。" }, { "id": "E2DE7B3B5BA943F6BEC0A9E32F6C4941", "createDate": "2021-06-11T15:10:01.75", "nickName": "纪茜茜", "introduce": "云想衣裳花想容，春风拂槛露华浓，若非群玉山头见，会向瑶台月下逢。" } ] }
