最近需要用单片机解析esp8266模块get到的json数据，顺便学习了下cJSON的知识，当作一个笔记吧，分享出来大家一起学习。这个是创建JSON字符串，后面还有解析。

1，下载源码

最新版的cJson源码可以从github上进行下载。

2，包含cJSON的源码

Jar包

实体类

 1 package bean;
 2 
 3 public class Question {
 4 
 5 private String timu; //题干
 6 private String leixing; //类型
 7 private String axuanxiang; //A选项
 8 private String bxuanxiang; //B选项
 9 private String cxuanxiang; //C选项
10 private String dxuanxiang; //D选项
11 private String daan; //答案
12 private String jiexi; //解析
13 public String getTimu() {
14 return timu;
15 }
16 public void setTimu(String timu) {
17 this.timu = timu;
18 }
19 public String getLeixing() {
20 return leixing;
21 }
22 public void setLeixing(String leixing) {
23 this.leixing = leixing;
24 }
25 
26 public String getAxuanxiang() {
27 return axuanxiang;
28 }
29 public void setAxuanxiang(String axuanxiang) {
30 this.axuanxiang = axuanxiang;
31 }
32 public String getBxuanxiang() {
33 return bxuanxiang;
34 }
35 public void setBxuanxiang(String bxuanxiang) {
36 this.bxuanxiang = bxuanxiang;
37 }
38 public String getCxuanxiang() {
39 return cxuanxiang;
40 }
41 public void setCxuanxiang(String cxuanxiang) {

44 public String getDxuanxiang() {
45 return dxuanxiang;

47 public void setDxuanxiang(String dxuanxiang) {
48 this.dxuanxiang = dxuanxiang;
49 }
50 public String getDaan() {
51 return daan;
52 }
53 public void setDaan(String daan) {
54 this.daan = daan;
55 }
56 public String getJiexi() {
57 return jiexi;
58 }
59 public void setJiexi(String jiexi) {
60 this.jiexi = jiexi;
61 }
62 @Override
63 public String toString() {
64 return "Question [timu=" + timu + ", leixing=" + leixing + ", axuanxiang=" + axuanxiang + ", bxuanxiang="
65 + bxuanxiang + ", cxuanxiang=" + cxuanxiang + ", dxuanxiang=" + dxuanxiang + ", daan=" + daan

JSON对象：

var str2 = { "name": "asan", "sex": "man" };

JSON字符串：

var str1 = '{ "name": "deyuyi", "sex": "man" }';
