Question

Tôi đang gặp phải vấn đề lạ, tôi rất mới đối với Android và Json. Tôi đang tiêu thụ một WCF RESTful cho thấy một phản ứng json như thế này:

Tôi đang cố gắng deserialize nó vào một đối tượng phức tạp với Jackson 1.9.11.

Vì vậy, tôi sử dụng

đâu RawResult là một lớp học với một mẫu và RawCatalogs một lớp học của mình với đối tượng lồng nhau, nó được sử dụng để deserialize phản ứng một cách chính xác, nhưng bây giờ nó hiển thị lỗi trong tiêu đề.

Định nghĩa của các lớp học được này (không biết nếu thông tin của các lớp lồng nhau là cần thiết để hỗ trợ đầy đủ? Tôi nghĩ rằng tôi đã ánh xạ chúng rất tốt, chỉ cần đi để đăng importants cho rõ ràng)

Vì vậy, câu hỏi của tôi là tại sao Nó hiển thị lỗi đó? Tôi đã tìm kiếm các câu hỏi tương tự trên stackoverflow, tất cả dường như về một lỗi mã hóa nhưng không phải là lỗi mã tương tự và tôi cũng không kiểm soát được WCF.

Thực ra Nếu tôi sao chép dán Json Respone vào this page thì có vẻ như nó đã được tạo thành.

Tôi cũng cố gắng sử dụng mapper.configure nhưng không ai trong số các tính năng của Jsonparser làm việc

Tôi đang làm gì sai?

Answer 1

Tôi gặp lỗi tương tự khi đọc tệp JSON.

Hoặc bạn đảm bảo rằng bạn nhận được phản hồi từ WCF RESTful của bạn mà không có 0xfeff ban đầu này hoặc bạn xóa nó trước khi gửi nó đến trình phân tích cú pháp JSON. Có thể trim() có thể làm thủ thuật ...
