提取 body 中的数据
老方法
/**
* obtain request body
*
* @param request the ServletRequest
* @return body string it maybe is null
*/
public static String obtainBody(ServletRequest request) {
BufferedReader br = null;
StringBuilder sb = new StringBuilder();
try {
br = request.getReader();
String str;
while ((str = br.readLine()) != null) {
sb.append(str);
}
br.close();
} catch (IOException e) {
log.error(" requestBody read error");
} finally {
if (null != br) {
try {
br.close();
} catch (IOException e) {
log.error(" close io error");
}
}
}
return sb.toString();
}
java8新方法
String body = request.getReader().lines().collect(Collectors.joining());
