如何使用Retrofit将字节数组从Web api发送到android客户端

implementation 'com.squareup.retrofit2:retrofit:2.9.0'

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("http://api.example.com/") // 替换为你的API基本URL
        .build();

public interface ApiService {
    @POST("your-endpoint") // 替换为你的API端点路径
    Call<ResponseBody> sendBytes(@Body RequestBody bytes);
}

ApiService apiService = retrofit.create(ApiService.class);
RequestBody requestBody = RequestBody.create(MediaType.parse("application/octet-stream"), yourByteArray);
Call<ResponseBody> call = apiService.sendBytes(requestBody);

call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        if (response.isSuccessful()) {
            // 处理成功响应
        } else {
            // 处理错误响应
        }
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        // 处理请求失败
    }
});
