获取ip地址的方法：
String ip = request.getHeader("x-forwarded-for");
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
}
获取body请求体中的数据的方法:
用io去读
BufferedReader reader = request.getReader();
String str, wholeStr ="";
while((str = reader.readLine()) != null){
wholeStr += str;
}
JSONObject params = new JSONObject().parseObject(wholeStr);
然后params.get("xx")就可以直接获取参数了 当然请求体中的数据得是json格式
