JAVA Http的Post请求传参添加Authorization Basic Auth验证

 PostMan添加Authorization验证

pom.xml添加依赖包

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-io</artifactId>
    <version>1.3.2</version>
</dependency>
或者引入
<dependency>
    <groupId>commons-httpclient</groupId>
    <artifactId>commons-httpclient</artifactId>
    <version>3.1</version>
</dependency>

通过PostMethod的方式（工具类）

package com.topnet.utils;

import lombok.extern.slf4j.Slf4j;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.RequestEntity;
import org.apache.commons.httpclient.methods.StringRequestEntity;

import java.io.*;
import java.nio.charset.Charset;
import java.util.Base64;

    /**

    public static String sendPost(String requestUrl, String params ) {
        InputStream inputStream = null;
        try {
            HttpClient httpClient = new HttpClient();
            PostMethod postMethod = new PostMethod(requestUrl);
            // 设置请求头  Content-Type
            postMethod.setRequestHeader("Content-Type", "application/json");
            //Base64加密方式认证方式下的basic auth HAIN460000：用户名    topicis123：密码
            postMethod.setRequestHeader("Authorization", "Basic " + Base64.getUrlEncoder().encodeToString(("HAIN460000" + ":" + "topicis123").getBytes()));
            RequestEntity requestEntity = new StringRequestEntity(params,"application/json","UTF-8");
            postMethod.setRequestEntity(requestEntity);
            httpClient.executeMethod(postMethod);// 执行请求
            inputStream =  postMethod.getResponseBodyAsStream();// 获取返回的流
            BufferedReader br = null;
            StringBuffer buffer = new StringBuffer();
            // 将返回的输入流转换成字符串
            br = new BufferedReader(new InputStreamReader(inputStream, Charset.forName("UTF-8")));
            String temp;
            while ((temp = br.readLine()) != null) {
                buffer.append(temp);
            }
            log.info("接口返回内容为:" + buffer);
            return buffer.toString();
        } catch (Exception e){
            log.info("请求异常" +e.getMessage());
            throw new RuntimeException(e.getMessage());
        } finally {
            if(inputStream != null) {
                try{
                    inputStream.close();
                } catch (IOException e){
                    e.printStackTrace();
                }
            }
        }
    }
}

测试

String parameter = "{ \"dto\":{\"purchaserPhone\":\"13798479813\" }}";
PostMethodUtils.sendPost(requestUrl,parameter);

结果

 "data":[
  {
   "id":10612514,
   "Name":"张三",
   "Dept":520100,
   "DeptCode":"fdrre",
   "DeptName":"贵州",
   "Date":"2020-12-05"
  }
 ]
