OkHttp示例REST客户端

OkHttp的HttpUrl和请求

OkHttpClient 提出请求有两个基本组成部分 HttpUrl 和 Request.Builder 。 HttpUrl 是在Java中构建URL的便捷方法。它支持parse(String host) 解析字符串的简单 方法，或者您可以手动构建URL。它允许轻松添加查询参数，路径参数不太直观，但仍然足够简单（可通过 Retrofit 获得更好的REST API支持）。该 Request.Builder 负责请求的大多数其他方面，包括HTTP verb, headers, cookies, media类型等。

RestClient

RestClient 将是我们的类，负责与REST服务进行交互。它的构造函数很简单。OkHttpClient 输入API 和主机名。

private final String host;
private final OkHttpClient client;
public RestClient(String host, OkHttpClient client) {
    super();
    this.host = host;
    this.client = client;
}

创建一个用户

根据我们的API，我们需要将JSON POST到 /users 。注意我们如何关心响应的状态码。我们知道API 201 成功创建后会返回a ，因此让我们来寻找它。我们宁愿返回 null ，也不愿因400 状态码而无法创建用户而引发异常 。这意味着用户已经存在。

public User createUser(User inputUser) {
    HttpUrl route = HttpUrl.parse(host + "/users");
    Request request = new Request.Builder()
        .url(route)
        .post(RequestBodies.jsonObj(inputUser))
        .build();
    return Unchecked.supplier(() -> {
        try (Response response = client.newCall(request).execute()) {
            if (response.code() == StatusCodes.CREATED) {
                User user = Json.serializer().fromInputStream(response.body().byteStream(), User.typeRef());
                return user;
            }
            if (response.code() == StatusCodes.BAD_REQUEST) {
                return null;
            }
            throw HttpClient.unknownException(response);
        }
    }).get();
}

更新用户

要进行更新，我们需要发送/users 带有更新的User对象的PUT请求 。在 404 （未找到）上，我们返回null而不是引发异常。

public User updateUser(User inputUser) {
    HttpUrl route = HttpUrl.parse(host + "/users");
    Request request = new Request.Builder()
            .url(route)
            .put(RequestBodies.jsonObj(inputUser))
            .build();
    return Unchecked.supplier(() -> {
        try (Response response = client.newCall(request).execute()) {
            if (response.isSuccessful()) {
                User user = Json.serializer().fromInputStream(response.body().byteStream(), User.typeRef());
                return user;
            }
            if (response.code() == StatusCodes.NOT_FOUND) {
                return null;
            }
            throw HttpClient.unknownException(response);
        }
    }).get();
}

列出用户

列出用户需要向发出GET请求 /users 。由于这是一个简单的示例，它将仅返回所有没有可用过滤或分页选项的用户。 response.isSuccessful() 是一种方便的方法，用于检查响应是否为任何 20x 状态码。

public List<User> listUsers() {
    HttpUrl route = HttpUrl.parse(host + "/users");
    Request request = new Request.Builder().url(route).get().build();
    return Unchecked.supplier(() -> {
        try (Response response = client.newCall(request).execute()) {
            if (response.isSuccessful()) {
                List<User> users = Json.serializer().fromInputStream(response.body().byteStream(), User.listTypeRef());
                return users;
            }
            throw HttpClient.unknownException(response);
        }
    }).get();
}

通过电子邮件获取用户

由于在此示例中我们将电子邮件用作主键，因此可以通过向发送GET请求来获取用户 /users/{email} 。我们再次404 通过返回null来处理 。

public User getUserByEmail(String email) {
    HttpUrl route = HttpUrl.parse(host + "/users")
                           .newBuilder()
                           .addPathSegment(email)
                           .build();
    Request request = new Request.Builder().url(route).get().build();
    return Unchecked.supplier(() -> {
        try (Response response = client.newCall(request).execute()) {
            // The user exists
            if (response.isSuccessful()) {
                User user = Json.serializer().fromInputStream(response.body().byteStream(), User.typeRef());
                return user;
            }
            /*
             *  404 Not Found - Either return null or throw your own exception.
             *  We prefer nulls.
             */
            if (response.code() == StatusCodes.NOT_FOUND) {
                return null;
            }
            throw HttpClient.unknownException(response);
        }
    }).get();
}

通过电子邮件删除用户

可以通过向发送一个DELETE请求来删除用户 /users/{email}。

public boolean deleteUserByEmail(String email) {
    HttpUrl route = HttpUrl.parse(host + "/users")
                           .newBuilder()
                           .addPathSegment(email)
                           .build();
    Request request = new Request.Builder().url(route).delete().build();
    return Unchecked.booleanSupplier(() -> {
        try (Response response = client.newCall(request).execute()) {
            if (response.code() == StatusCodes.NO_CONTENT) {
                return true;
            }
            // Maybe you would throw an exception here? We don't feel the need to.
            if (response.code() == StatusCodes.NOT_FOUND) {
                return false;
            }
            throw HttpClient.unknownException(response);
        }
    }).getAsBoolean();
}

用法示例

如果要在本地进行测试，请确保还启动示例REST服务。

public static void main(String[] args) {
    RestClient client = new RestClient("http://localhost:8080", HttpClient.globalClient());
    log.debug("**** Creating Users ****");
    User user1 = new User("user1@test.com", Sets.newHashSet(Role.USER), LocalDate.now());
    log.debug(Json.serializer().toString(client.createUser(user1)));
    User user2 = new User("user2@test.com", Sets.newHashSet(Role.ADMIN), LocalDate.now());
    log.debug(Json.serializer().toString(client.createUser(user2)));
    log.debug("\n\n");
    log.debug("**** Updating User ****");
    User user2Updated = new User("user2@test.com", Sets.newHashSet(Role.ADMIN, Role.USER), LocalDate.now());
    log.debug(Json.serializer().toString(client.updateUser(user2Updated)));
    log.debug("\n\n");
    log.debug("**** Listing Users ****");
    List<User> users = client.listUsers();
    log.debug(Json.serializer().toString(users));
    log.debug("\n\n");
    log.debug("**** Get Users ****");
    log.debug(Json.serializer().toString(client.getUserByEmail("user1@test.com")));
    log.debug(Json.serializer().toString(client.getUserByEmail("user2@test.com")));
    log.debug("\n\n");
    log.debug("**** Delete Users ****");
    client.deleteUserByEmail("user1@test.com");
    log.debug("\n\n");
    log.debug("**** Get Missing User ****");
    log.debug(Json.serializer().toString(client.getUserByEmail("user1@test.com")));
    log.debug("\n\n");
    log.debug("**** Exception ****");
    log.debug(Json.serializer().toString(client.createUser(null)));
}

输出

由于我们 OkHttpClient 已经配置了拦截器，因此 我们可以获得非常详细的输出。您可能希望在生产中关闭此级别的日志记录。
