如何从 MultipartFormData 中获取 DataPart?我找不到任何 API 来获取它。
Http.MultipartFormData formData = body.asMultipartFormData();
// simple form field
// there is NO getData() or something available
DataPart imageIdPart = formData.getData("dataKey");
// uploaded file
FilePart imagePart = formData.getFile("imageKey");
