本文介绍了JSON无效的UTF-8中间字节的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
当(Jackson,本例)JSON引擎试图解析一些未以UTF-8编码的JSON时会发生此错误。
This error happens when the (Jackson, this case) JSON engine tries to parse some JSON that is not encoded in UTF-8.
如何告诉引擎它应该期望与UTF-8不同的东西,例如UTF-16?
How to tell the engine that it should expect something different from UTF-8, such as UTF-16?
HttpHeaders requestHeaders = createSomeHeader();
RestTemplate restTemplate = new RestTemplate();
HttpEntity<?> requestEntity = new HttpEntity<Object>(requestHeaders);
String url = "someurl"
ResponseEntity<MyObject[]> arrayResponseEntity = restTemplate.exchange(url, HttpMethod.GET, requestEntity, MyObject[].class);

推荐答案
JSON数据必须编码为UTF-8,UTF-16或UTF-32。 JSON解码器可以通过来确定编码:
JSON data must be encoded as UTF-8, UTF-16 or UTF-32. The JSON decoder can determine the encoding by examining the first four octets of the byte stream:
00 00 00 xx UTF-32BE
00 xx 00 xx UTF-16BE
xx 00 00 00 UTF-32LE
xx 00 xx 00 UTF-16LE
xx xx xx xx UTF-8
听起来服务器正在以某种非法编码(ISO-8859-1,windows-1252等)编码数据
It sounds like the server is encoding data in some illegal encoding (ISO-8859-1, windows-1252, etc.)
