如何使用body发起android截击请求，如下

import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

OkHttpClient client = new OkHttpClient();

String url = "https://example.com/api/endpoint";
String jsonBody = "{\"key1\":\"value1\", \"key2\":\"value2\"}"; // 替换为你的请求体内容
MediaType mediaType = MediaType.parse("application/json; charset=utf-8");
RequestBody requestBody = RequestBody.create(jsonBody, mediaType);

Request request = new Request.Builder()
        .url(url)
        .post(requestBody)
        .build();

try {
    Response response = client.newCall(request).execute();
    String responseBody = response.body().string();
    // 处理响应数据
} catch (IOException e) {
    e.printStackTrace();
}
