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。

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);
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
Map<String, Object> object=HttpJsonUtil.get("https://github.com/search",
Pair.of("q","http"),
Pair.of("username","agonie201218"));
System.out.println("object = "+object);
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);
HttpUtil.down("https://gitee.com/admin4j/common-http","path/");
# 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;
}
}
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
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 Map<String, Object> 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);
Map<String, Object> jsonObject=ebayInventoryClient.inventoryItem(0,10);
/**
* 订单相关api
*
* @author andanyang
* @since 2022/11/8 17:34
*/
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 Map<String, Object> 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
项目默认使用 fastjson 解析json，如果想用其他json框架.排除admin4j-json-fastjson,重新导入其他包参考如下

<exclusions>
<exclusion>
<groupId>com.admin4j.json</groupId>

</dependency>
<dependency>
