返回数据解析错误
com.google.gson.JsonSyntaxException:
java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path
期望返回一个对象但是却返回了一个数组
解决办法:
1.在参数中修改期望返回类 Student 为 LIst< Student>,这样才能解析到数据。
2.用 TypeToken 转一下:
Gson gson = new Gson();
String result = response;
ArrayList<Student> list = new ArrayList<Student>();
Type listType = new TypeToken<List<Student>>() {}.getType();
list = gson.fromJson(result, listType);
