使用OkHttp进行取消呼叫时的SocketException

OkHttpClient client = new OkHttpClient();

// 创建一个请求
Request request = new Request.Builder()
        .url("http://www.example.com")
        .build();

// 发送请求
Call call = client.newCall(request);
call.enqueue(new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
        if (call.isCanceled()) {
            // 请求被取消
            System.out.println("请求被取消");
        } else {
            // 请求失败
            System.out.println("请求失败：" + e.getMessage());
        }
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        // 处理响应
        System.out.println("请求成功：" + response.body().string());
    }
});

// 取消呼叫
call.cancel();
