在Spring Boot中使用OKHttpUtil封装OkHttp简化HTTP请求-开发者社区-阿里云

OKHttpUtil

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。

基于 Spring Boot + MyBatis Plus + Vue & Element 实现的后台管理系统 + 用户小程序，支持 RBAC 动态权限、多租户、数据权限、工作流、三方登录、支付、短信、商城等功能

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

OKHttpUtil使用

maven引入

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

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);

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);

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);

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);

spring 版可以对 OkHttp进行个性化配置配置详见

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;
    }
}

如何快速封装外部接口

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<>();
        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,是不是很清晰
