JSON parse error: Invalid UTF-8 start byte 0x8b 異常的記錄

原創 慕紫羽 2018-09-06 13:35

最近在使用Postman測試接口，POST請求發送JSON格式的數據。之前一直風平浪靜，沒什麼問題。不過最近測試一直失敗，得到的響應是500內部錯誤，於是去服務器看錯誤信息，信息如下：

網上查相關資料說是什麼響應消息頭的問題，又說是編碼的問題，我想了想我的情況應該不是，畢竟之前也是按照這個來的，一直沒啥問題。這個異常很清楚，JSON解析失敗了，至於爲什麼會失敗，原因讓我很無語。

原來最近終端工具從CRT換成了MobaXterm，從生產環境拷貝數據到測試時，竟然發現它在JSON串中加入了兩個>符號，這個符號被加在了中文串中，不容易發現，並且使用JSON格式化校驗也查不出問題來。而就是這個藏在中文串中的符號存在，所以導致fastJson解析失敗了，我想正是這個字符被加入其中卻沒有轉義的原因。於是我把這兩個>字符刪掉後，終於成功的調通了接口。

可見，使用fastJSON解析JSON數據時，遇到這些特殊字符，如果不轉義，就可能出現此異常。 需要被轉義
