okhttp android socket 发送sendmessage消息

要使用 OkHttp 在 Android 应用中发送 Socket 消息，可以按照以下步骤：

1. 添加 OkHttp 依赖
在 app 的 build.gradle 文件中添加 OkHttp 依赖：

dependencies {
    implementation 'com.squareup.okhttp3:okhttp:4.9.0'
}

2. 创建 OkHttpClient 对象

OkHttpClient client = new OkHttpClient();

3. 创建 Socket 连接

Socket socket = new Socket("your_server_ip_address", your_server_port_number);

4. 获取 Socket 的输入输出流

OutputStream outputStream = socket.getOutputStream();
InputStream inputStream = socket.getInputStream();

5. 向服务器发送消息

String message = "your_message";
outputStream.write(message.getBytes());

6. 接收服务器返回的消息

byte[] response = new byte[1024];
int length = inputStream.read(response);
String responseString = new String(response, 0, length);

7. 关闭连接和流

outputStream.close();
inputStream.close();
socket.close();

完整的示例代码如下：

OkHttpClient client = new OkHttpClient();

try {
    Socket socket = new Socket("your_server_ip_address", your_server_port_number);

    OutputStream outputStream = socket.getOutputStream();
    InputStream inputStream = socket.getInputStream();

    String message = "your_message";
    outputStream.write(message.getBytes());

    byte[] response = new byte[1024];
    int length = inputStream.read(response);
    String responseString = new String(response, 0, length);

    outputStream.close();
    inputStream.close();
    socket.close();
} catch (IOException e) {
    e.printStackTrace();
}
