使用retrofit2上传视频

implementation 'com.squareup.retrofit2:retrofit:2.x.x'
implementation 'com.squareup.retrofit2:converter-gson:2.x.x' // 如果需要使用Gson进行数据转换

public interface VideoUploadService {
    @Multipart
    @POST("upload/video")
    Call<ResponseBody> uploadVideo(@Part MultipartBody.Part video);
}

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.example.com/") // 设置API的基础URL
        .addConverterFactory(GsonConverterFactory.create()) // 设置数据转换器为Gson
        .build();

VideoUploadService uploadService = retrofit.create(VideoUploadService.class);

File videoFile = new File("path/to/video.mp4");
RequestBody videoRequestBody = RequestBody.create(MediaType.parse("video/mp4"), videoFile);
MultipartBody.Part videoPart = MultipartBody.Part.createFormData("video", videoFile.getName(), videoRequestBody);

Call<ResponseBody> call = uploadService.uploadVideo(videoPart);
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
    }
});
