依赖

<dependency>

    <artifactId>okhttp</artifactId>
    <version>3.10.xxx</version>
</dependency>

1.发送Get请求

/**
   * GET请求
   */
public static String get(String url) throws IOException {
    OkHttpClient client = new OkHttpClient();
    Request request = new Request.Builder()
        .get()
        .url(url)
        .build();
    Response response = client.newCall(request).execute();
    return response.body().string();
}

// 调用
String objStr = OkHttpUtil.get(url);

2.发送Post请求

表单数据提交

/**
 * POST:表单数据提交
 */
public static void postFormBody(String url, FormBody formBody) throws IOException {
    OkHttpClient client = new OkHttpClient();
    final Request request = new Request.Builder()
        .url(url)
        .post(formBody)
        .build();
    Response response = client.newCall(request).execute();
    return response.body().string();
}

// 调用
FormBody formBody = new FormBody.Builder()
    .add("id", id.toString())
    .build();
OkHttpUtil.postFormBody(url, formBody);

json数据提交

/**
 * POST:json数据提交
 */
public static String postJsonBody(String url, String jsonBody) throws IOException {
    OkHttpClient client = new OkHttpClient();
    MediaType mediaType = MediaType.parse("application/json");
    RequestBody body = RequestBody.create(mediaType, jsonBody);
    final Request request = new Request.Builder()
        .url(url)
        .post(body)
        .build();
    Response response = client.newCall(request).execute();
    return response.body().string();
}

// 调用
String config = "{\"id\": 123}";
String response = OkHttpUtil.postJsonBody(url, config);

3.Delete请求

/**
 * DELETE
 */
public static String delete(String url, String jsonBody) throws IOException {
    OkHttpClient client = new OkHttpClient();
    MediaType mediaType = MediaType.parse("application/json");
    RequestBody body = RequestBody.create(mediaType, jsonBody);
    Request request = new Request.Builder()
        .url(url)
        .method("DELETE", body)
        .addHeader("Content-Type", "application/json")
        .build();
    Response response = client.newCall(request).execute();
    return response.body().string();
}

// 调用
String response = OkHttpUtil.delete(url, "");
