Error contents:
expect ':' at 0, actual = com.alibaba.fastjson.JSONException: expect ':' at 0, actual =
the reason:
The exception is an exception, certainly not the run-time syntax errors.
Means JSONEObject translation exception, typically () method of the position error fromObject .
Check your code JSONEObject.fromObject (result) code location, parameter result does not meet the definition of Json format, so can not be converted into a Json format, resulting in reported above error.
Solution:
Good check under your result parameters, defined in terms of Json specification.
If we want an output result, marks may be applied across the parameters: Result = "[" + Result + "]";
