Json标准格式(json正确数据格式)

１．Exception in thread "main" com.alibaba.fastjson.JSONException: syntax error, expect {, actual ]　
就是说实际上想要的是｛｝，而不是［］

错误案例：　String request = "[\"data\"=\"today\", \"type\"=\"JSON\"]"

（只要是这种都是格式不正确，还有比如syntax error, expect ：, actual ＝等等）

错误案例：　String request = "{\"data\"=\"today\", \"type\"=\"JSON\"}"

２．com.alibaba.fastjson.JSONException: syntax error,

错误案例：　String request = "{data:today, type:JSON}";


正确案例：String request = "{\"data\":\"today\", \"type\":\"JSON\"}";

JSONObject obj = JSON.parseObject(request);
