我有一个API，客户端可以通过发送压缩的请求向其发出请求。使用Deflator的以下方式进行压缩。
请求有效载荷：
public byte[] compressRequest(String requestString) {
int reqLength = requestString.length();
int temp = (int)(1.001D * (double)reqLength + 1.0D) + 12;
byte[] byteArr = requestString.getBytes("US-ASCII");
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(temp);
DeflaterOutputStream deflaterOutputStream = new DeflaterOutputStream(byteArrayOutputStream);
deflaterOutputStream.write(byteArr);
deflaterOutputStream.close();
return byteArrayOutputStream.toByteArray();
}
在服务器端，我试图按照以下方式提取和解压缩数据。
相同的代码在基于Java7和Servlet的应用程序上运行良好。但是在基于Java 8和基于Spring Boot的应用程序中，我在行java.io.EOFException: Unexpected end of ZLIB input stream的第inputLine = in.readLine())行之后出现了异常@PostMapping(value = "saverecord")
public void hello(HttpServletRequest request,HttpServletResponse response) {
response.setContentType("application/binary");
InflaterInputStream is = InflaterInputStream(request.getInputStream());
String requestXMLStr = extract(is,0);
ServletOutputStream out = response
.getOutputStream();
// some processing and return response
}
private String extract(InputStream is) throws IOException {
StringBuffer sb = new StringBuffer();
BufferedReader in = new BufferedReader(new InputStreamReader(is));
String inputLine;
while ((inputLine = in.readLine()) != null) {
sb.append(inputLine);
}
return sb.toString();
}
InflaterInputStream is = InflaterInputStream(request.getInputStream(),new Inflater(false)); // tried true also
我尝试遵循其他SO答案中建议的两件事，但均无济于事。
BufferedReader in = new BufferedReader(new InputStreamReader(is,"US-ASCII"));
尝试设置编码
@RequestBody PS：出于某些项目特定的原因，我无法在项目中使用"eofline": true,。
