如何通过 Rest API 从 flutter 上传音频文件到 wordpress

Question

I am able to upload images via API to WordPress but not audio files, it gives HTTP 500 error when I try to pass the Audio file to the method. But when I pass the image it uploads successfully, here is the function.

I'm using the Dio package.

Future<bool> UploadFileToWordpress(File file) async {

    try {
      final token = MyConstant.token;

      String apiURL = "https://prostate-wrench.000webhostapp.com";
      String uri = "$apiURL/wp-json/wp/v2/media";

      String fileName = file.path
          .split('/')
          .last;
      print(fileName);

      FormData data = FormData.fromMap({
        "file": await MultipartFile.fromFile(
          file.path,
          filename: fileName,
        ),
      });

      Dio dio = Dio(BaseOptions(
          headers: {
            'Authorization': 'Bearer ${MyConstant.token}'
          },
          contentType: "application/json")
      );
      var response = await dio.post(uri, data: data);
      print(response.statusMessage);
      if (response.statusCode == 201) {
        return true;
      } else {
        return false;
      }

   
    }catch(e){
      print(e.toString());
      return false;
    }
  }

Answer 1

Got it.. added ".mp3" extension with filename variable and its perfect now

Answer 2

FormData data = FormData.fromMap({
        "file": await MultipartFile.fromFile(
          file.path,
          filename: fileName,
          contentType: ...,//need to add this part 
        ),
      });

import 'package:mime/mime.dart'; //don't forget import

var lookUpMime =lookupMimeType(file.path);

now need to split type

      var mimeString = mimeType.split('/')[0];
      var mimeType = mimeType.split('/')[1];

and add it as contentType:

contentType: MediaType(mimeString, mimeType),

I think it helps
