围子先生   2021-09-11 我要评论
想了解SpringBoot打印POST请求原始入参body体方式的相关内容吗,围子先生在本文为您仔细讲解SpringBoot打印POST请求body的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:SpringBoot,POST请求,打印POST请求,原始入参body体,下面大家一起来学习吧。

SpringBoot打印POST请求原始入参body体

1、首先定义过滤器配置

package com.choice.o2o.device.common.config; 
import com.choice.o2o.device.common.filter.LogFilter;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration; 
@Configuration
public class FilterConfig {
 
    @Bean
    public FilterRegistrationBean registFilter() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new LogFilter());
        registration.addUrlPatterns("/*");
        registration.setName("LogFilter");
        registration.setOrder(1);
        return registration;
    }
}

2、实现1中的过滤器

package com.choice.o2o.three.code.config.log; 
import lombok.extern.slf4j.Slf4j;
import org.springframework.core.Ordered;
import org.springframework.web.filter.OncePerRequestFilter;
import org.springframework.web.util.ContentCachingRequestWrapper;
import org.springframework.web.util.ContentCachingResponseWrapper;
import org.springframework.web.util.WebUtils; 
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.Enumeration;
 
@Slf4j
public class LogParamFilter extends OncePerRequestFilter implements Ordered {
    // put filter at the end of all other filters to make sure we are processing after all others
    private int order = Ordered.LOWEST_PRECEDENCE - 8;
    public static final String SPLIT_STRING_M = "=";
    public static final String SPLIT_STRING_DOT = ", ";
 
    @Override
    public int getOrder() {
        return order;
    }
 
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
                                    FilterChain filterChain) throws ServletException, IOException {
        ContentCachingRequestWrapper wrapperRequest = new ContentCachingRequestWrapper(request);
        ContentCachingResponseWrapper wrapperResponse = new ContentCachingResponseWrapper(response);
        String urlParams = getRequestParams(request);
        filterChain.doFilter(wrapperRequest, wrapperResponse);
 
        String requestBodyStr = getRequestBody(wrapperRequest);
        log.info("params[{}] | request body:{}", urlParams, requestBodyStr);
 
        String responseBodyStr = getResponseBody(wrapperResponse);
        log.info("response body:{}", responseBodyStr);
        wrapperResponse.copyBodyToResponse();
    }
 
    /**
     * 打印请求参数
     *
     * @param request
     */
    private String getRequestBody(ContentCachingRequestWrapper request) {
        ContentCachingRequestWrapper wrapper = WebUtils.getNativeRequest(request, ContentCachingRequestWrapper.class);
        if (wrapper != null) {
            byte[] buf = wrapper.getContentAsByteArray();
            if (buf.length > 0) {
                String payload;
                try {
                    payload = new String(buf, 0, buf.length, wrapper.getCharacterEncoding());
                } catch (UnsupportedEncodingException e) {
                    payload = "[unknown]";
                }
                return payload.replaceAll("\\n", "");
            }
        }
        return "";
    }
 
    /**
     * 打印返回参数
     *
     * @param response
     */
    private String getResponseBody(ContentCachingResponseWrapper response) {
        ContentCachingResponseWrapper wrapper = WebUtils.getNativeResponse(response,
                ContentCachingResponseWrapper.class);
        if (wrapper != null) {
            byte[] buf = wrapper.getContentAsByteArray();
            if (buf.length > 0) {
                String payload;
                try {
                    payload = new String(buf, 0, buf.length, wrapper.getCharacterEncoding());
                } catch (UnsupportedEncodingException e) {
                    payload = "[unknown]";
                }
                return payload;
            }
        }
        return "";
    }
 
    /**
     * 获取请求地址上的参数
     *
     * @param request
     * @return
     */
    public static String getRequestParams(HttpServletRequest request) {
        StringBuilder sb = new StringBuilder();
        Enumeration<String> enu = request.getParameterNames();
        //获取请求参数
        while (enu.hasMoreElements()) {
            String name = enu.nextElement();
            sb.append(name + SPLIT_STRING_M).append(request.getParameter(name));
            if (enu.hasMoreElements()) {
                sb.append(SPLIT_STRING_DOT);
            }
        }
        return sb.toString();
    }
}

Post接收不到body里的参数(对象参数)

检查注解

  • @ResponseBody
  • @RequestBody

检查实体

接收实体类,set、get方法是否正确

检查Content-Type

是否是application/json

以上为个人经验,希望能给大家一个参考,也希望大家多多支持。
