尝试使用okhttpClient连接到URL以获取Json

dependencies {
    implementation 'com.squareup.okhttp3:okhttp:版本号'
}

OkHttpClient client = new OkHttpClient();

Request request = new Request.Builder()
        .url("http://example.com/api/data.json")
        .build();

client.newCall(request).enqueue(new Callback() {
    @Override
    public void onResponse(Call call, Response response) throws IOException {
        if (response.isSuccessful()) {
            String jsonData = response.body().string();
            // 在这里处理JSON数据
        } else {
            // 处理请求失败的情况
        }
    }

    @Override
    public void onFailure(Call call, IOException e) {
        // 处理请求失败的情况
    }
});
