前端用Request Payload方式請求后台

后台接收方式：

 

InputStream inputStream = request.getInputStream();

byte[] buff = new byte[1024];
int len = -1;
while (-1 != (len = inputStream.read(buff))) {
// 將字節數組轉換為字符串，並且設置為“UTF-8”格式編碼（不然會出現亂碼）
String res = new String(buff, 0, len,"UTF-8");
jsonObject = new org.json.JSONObject(res);

int offset = jsonObject.getInt("offset");
int limit = jsonObject.getInt("limit");
}
