　　在项目中会用到各种类型的http请求，包含put，get，post，delete，formData等各种请求方式，在这里总结一下

用过比较好的请求工具，使用service方法封装。

　　代码如下：

1.依赖的maven

<dependency>

      <groupId>org.apache.httpcomponents</groupId>

      <artifactId>httpclient</artifactId>

      <version>4.5.2</version>

    </dependency>

2.封装请求返回的实体类

@Setter

@Getter

public class ApacheHttpClientResult {

    /** 状态码 **/

    private int statusCode;

    /** 响应内容 **/

    private String responseContent;

}

3.封装各类型请求的方法

import java.util.Map;

import org.apache.http.entity.mime.MultipartEntityBuilder;

import com.vo.ApacheHttpClientResult;

public interface ApacheHttpClientService {

    public ApacheHttpClientResult postForJson(String uri, String param) throws CustomException;

    public ApacheHttpClientResult postForJson(String uri, MultipartEntityBuilder param)throws CustomException;

    public ApacheHttpClientResult getForObject(String uri)throws CustomException;

    public ApacheHttpClientResult putForJson(String uri, String param)throws CustomException;

    public ApacheHttpClientResult deleteForJson(String uri, String param)throws CustomException;

    public ApacheHttpClientResult postForJson(String uri, String param, Map<String, String> headers)throws CustomException;

    public ApacheHttpClientResult getForObject(String uri, Map<String, String> headers)throws CustomException;

    public ApacheHttpClientResult putForJson(String uri, String param, Map<String, String> headers)throws CustomException;

    public ApacheHttpClientResult deleteForJson(String uri, String param, Map<String, String> headers)throws CustomException;

    public ApacheHttpClientResult getForObjectCloud(String uri, Map<String, String> headers) throws CustomException;

    public ApacheHttpClientResult getForObjectCloud(String uri) throws CustomException;

    public ApacheHttpClientResult postForJsonNoProxy(String uri, String param) throws CustomException;

    public ApacheHttpClientResult postForJson(String uri, String param, Map<String, String> headers, Map<String, String> resultHeaders);

    public ApacheHttpClientResult putForJson(String uri, String param, Map<String, String> headers,  Map<String, String> resultHeaders);

}

4.实现类

import java.io.Closeable;

import java.io.IOException;

import java.net.Proxy;

import java.util.Map;

import org.apache.commons.lang3.StringUtils;

import org.apache.http.Header;

import org.apache.http.client.methods.CloseableHttpResponse;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.client.methods.HttpPut;

import org.apache.http.entity.StringEntity;

import org.apache.http.entity.mime.MultipartEntityBuilder;

import org.apache.http.impl.client.CloseableHttpClient;

import org.apache.http.impl.client.HttpClientBuilder;

import org.apache.http.impl.client.HttpClients;

import org.apache.http.util.EntityUtils;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.http.MediaType;

import org.springframework.stereotype.Service;

import com.common.CustomException;

import com.common.HttpDeleteWithBody;

import com.intf.service.common.ApacheHttpClientService;

import com.vo.ApacheHttpClientResult;
