okhttp 分片上传代码

以下是使用OkHttp进行分片上传的示例代码：

import okhttp3.*;

import java.io.File;
import java.io.IOException;

public class OkHttpChunkedUploadExample {
    private static final String FILE_PATH = "/path/to/file"; // 文件路径
    private static final String UPLOAD_URL = "http://example.com/upload"; // 上传接口URL

    public static void main(String\[\] args) {
        File file = new File(FILE_PATH);

        OkHttpClient client = new OkHttpClient();

        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("file", file.getName(), RequestBody.create(MediaType.parse("application/octet-stream"), file))
                .build();

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

        try (Response response = client.newCall(request).execute()) {
            if (response.isSuccessful()) {
                System.out.println("文件上传成功");
            } else {
                System.out.println("文件上传失败");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

请注意，这只是一个简单的示例代码，你需要根据你的实际需求进行适当的修改。在这个示例中，我们使用OkHttp库创建了一个POST请求，将文件作为表单数据进行上传。你需要将`FILE_PATH`替换为你要上传的文件的实际路径，将`UPLOAD_URL`替换为你的上传接口的URL。
