构造配置实例

Config config = Config.builder()
    .appid("your appid")
    .mchId("your mchId")
    .key("your key")
    .secret("your secret")
    .build();

构造请求执行器实例

InputStream in = ...;
KeyStore keyStore = KeyStore.getInstance("JKS");
keyStore.load(in, "your password".toCharArray());

SSLContext sslContext = SSLContextBuilder.create().loadKeyMaterial(keyStore, "your password".toCharArray()

HttpClientExecutor httpClient = new HttpClientExecutor(2000, 2000, 3000, sslContext);
RequestExecutor executor = new RequestExecutor(httpClient, config);

// 在必要的时候关闭
executor.close();

使用方式

// 普通请求
Request req = ...;
Response resp = executor.execute(req);

// 涉及下载文件的请求
Request req = ...;
ResponseBodyHandler handler = ...;
Response resp = executor.execute(req, handler);
