1 OKHttpUtil

1.1 引言

在Java的世界中，Http客户端之前一直是Apache家的HttpClient占据主导，但是由于此包较为庞大，API又比较难用，因此并不使用很多场景。而新兴的OkHttp、Jodd-http固然好用，但是面对一些场景时，学习成本还是有一些的。

很多时候，我们想追求轻量级的Http客户端，并且追求简单易用。而OKHttp是一套处理 HTTP 网络请求的依赖库，由 Square 公司设计研发并开源，目前可以在 Java 和 Kotlin 中使用。

对于 Android App来说，OkHttp 现在几乎已经占据了所有的网络请求操作，对于服务器端请求外部接口也是必备的选择。针对OKHttp，OkHttpUtil做了一层封装，使Http请求变得无比简单

1.2 OKHttpUtil功能

OKHttpUtil功能：

根据URL自动判断是请求HTTP还是HTTPS，不需要单独写多余的代码。
默认情况下Cookie自动记录，比如可以实现模拟登录，即第一次访问登录 URL后后续请求就是登录状态。
自动识别304跳转并二次请求
支持代理配置
支持referer配置
支持User-Agent配置
自动识别并解压Gzip格式返回内容
支持springboot 配置文件
极简的封装调用

1.3 OKHttpUtil使用

1.3.1 maven引入

<dependency>
    <groupId>io.github.admin4j</groupId>
    <artifactId>http</artifactId>
    <version>0.4.0</version>
</dependency>

1.3.2 GET

最简单的使用莫过于用HttpUtil工具类快速请求某个接口：

Response response = HttpUtil.get(https://github.com/search, Pair.of(q, okhttp));
System.out.println(response =  + response);

1.3.3 POST

一行代码即可搞定，当然Post请求也很简单：
JSON 格式的body


Response post = HttpUtil.post(https://oapi.dingtalk.com/robot/send?access_token=27f5954ab60ea8b2e431ae9101b1289c138e85aa6eb6e3940c35ee13ff8b6335, {\msgtype\: \text\,\text\: {\content\:\【反馈提醒】我就是我, 是不一样的烟火\}});
System.out.println("post = "+ post);

form 请求

Map<String, Object> formParams = new HashMap<>(16);
formParams.put(username, admin);
formParams.put(password, admin123);
Response response = HttpUtil.postForm(http://192.168.1.13:9100/auth/login,formParams);
System.out.println("response = "+ response);

返回格式为JSON的，可以使用 HttpJsonUtil 自动返回JsonObject

JSONObject object=HttpJsonUtil.get(https://github.com/search,
Pair.of(q,http),
Pair.of(username,agonie201218));
System.out.println("object = "+object);

1.3.4 文件上传与下载

文件上传

File file=new File(C:\\Users\\andanyang\\Downloads\\Sql.txt);
Map<String, Object> formParams=new HashMap<>();
formParams.put(key,test);
formParams.put(file,file);
formParams.put(token,WXyUseb-D4sCum-EvTIDYL-mEehwDtrSBg-Zca7t:qgOcR2gUoKmxt-VnsNb657Oatzo=:eyJzY29wZSI6InpoYW56aGkiLCJkZWFkbGluZSI6MTY2NTMwNzUxNH0=);
Response response=HttpUtil.upload(https://upload.qiniup.com/,formParams);
System.out.println(response);

文件下载

HttpUtil.down(https://gitee.com/admin4j/common-http,path/);

1.3.5 HttpRequest 链式请求

get

Response response = 
	 HttpRequest.get(https://search.gitee.com/?skin=rec&type=repository)
	.queryMap(q,admin4j)
	.header(HttpHeaderKey.USER_AGENT,admin4j)
	.execute();
System.out.println("response = "+ response);

post form

Response response = 
	HttpRequest.get(http://192.168.1.13:9100/auth/login)
	.queryMap(q,admin4j)
	.header(HttpHeaderKey.USER_AGENT,admin4j)
	.form(username,admin)
	.form(password,admin123)
	.execute();
System.out.println("response = "+response);

1.3.6 post form日志

1.4 在 Springboot 中使用

1.4.1 maven引入

<dependency>
    <groupId>io.github.admin4j</groupId>
    <artifactId>common-http-starter</artifactId>
    <version>0.4.0</version>
</dependency>

最新版查询 io.github.admin4j:common-http-starter
spring 版可以对 OkHttp进行个性化配置

1.4.2 配置

public class HttpConfig {
    /**
     * 日志等级
     */
    private HttpLoggingInterceptor.Level loggLevel = HttpLoggingInterceptor.Level.BODY;
    /**
     * 读取超时时间，秒
     */
    private long readTimeout = 30;
    /**
     * 链接超时时间
     */
    private long connectTimeout = 30;

    private boolean followRedirects = false;
   /**
     * 最大的连接数
     */
    private int maxIdleConnections = 5;
    /**
     * 最大的kepAlive 时间 秒
     */
    private long keepAliveDuration = 5;

    private String userAgent = OKHTTP;
    /**
     * 是否支持cookie
     */
    private boolean cookie = false;
    private ProxyConfig proxy;
    
    @Data
    public static class ProxyConfig {
        private Proxy.Type type = Proxy.Type.HTTP;
        private String host;
        private Integer port = 80;
        private String userName;
        private String password;
    }
}

1.4.3 快速封装外部接口

以实体项目为例，封装 ebay接口

public class EbayClient extends ApiJsonClient {
    /**
     * 店铺配置
     *
     * @param storeId
     */
    public EbayClient(Long storeId) {

        //TODO 获取店铺相关配置
        Map<String, String> config = new HashMap<>();

        String basePath = "https://api.ebay.com";
        defaultHeaderMap.put(Authorization, Bearer  + config.get(accessToken));
        defaultHeaderMap.put(X-EBAY-C-MARKETPLACE-ID, config.get(marketplaceId));
    }
}

EbayClient 封装ebay api请求基础类

/**
 * ebay 库存相关api
 * @author andanyang
 */
public class EbayInventoryClient extends EbayClient {

    /**
     * 店铺配置
     *
     * @param storeId
     */
    public EbayInventoryClient(Long storeId) {
        super(storeId);
    }

    /**
     * 库存列表
     *
     * @param limit
     * @param offset
     * @return
     * @throws IOException
     */
    public JSONObject inventoryItem(Integer limit, Integer offset) throws IOException {

        Map<String, Object> queryMap = new HashMap(2);
        queryMap.put(limit, limit);
        queryMap.put(offset, offset);
        return get(/sell/inventory/v1/inventory_item, queryMap);
    }
}

EbayInventoryClient 封装ebay 库存 api请求

使用

EbayInventoryClient ebayInventoryClient=new EbayInventoryClient(1L);
JSONObject jsonObject=ebayInventoryClient.inventoryItem(0,10);

/**
 * 订单相关api
 * @author andanyang
 */
public class EbayOrderClient extends EbayClient {


    /**
     * 店铺配置
     *
     * @param storeId
     */
    public EbayOrderClient(Long storeId) {
        super(storeId);
    }

    /**
     * 订单列表
     *
     * @param beginTime
     * @param endTime
     * @param limit
     * @param offset
     * @return
     */
    public JSONObject orders(String beginTime, String endTime, int limit, int offset) {

        final String path = /sell/fulfillment/v1/order;

        String filter = MessageFormat.format(lastmodifieddate:[{0}..{1}], beginTime, endTime);

        //
        Map<String, Object> queryMap = new HashMap<>(8);
        queryMap.put(filter, filter);
        queryMap.put(limit, limit);
        queryMap.put(offset, offset);

        return get(/sell/inventory/v1/inventory_item, queryMap);
    }
}

库存相关的使用EbayInventoryClient，订单相关的使用EbayOrderClient
