使用Retrofit to flask api上传音频文件

// 1. 配置Retrofit客户端
Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("http://your-flask-api-url.com/")
    .build();

// 2. 创建API接口
interface ApiInterface {
    @Multipart
    @POST("upload-audio")
    Call<ResponseBody> uploadAudio(@Part MultipartBody.Part audioFile);
}

// 3. 定义请求参数
File file = new File("/path/to/audio/file.mp3");
RequestBody requestBody = RequestBody.create(MediaType.parse("audio/*"), file);
MultipartBody.Part audioPart = MultipartBody.Part.createFormData("audio", file.getName(), requestBody);

// 4. 执行上传
ApiInterface api = retrofit.create(ApiInterface.class);
Call<ResponseBody> call = api.uploadAudio(audioPart);
call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        // 处理上传成功的响应
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        // 处理上传失败的情况
    }
});
