标签：install 报错 webapi cat info qrcode format pixel turn
发现：service中有个webapi输出了：
public Bitmap GetLogoQRCode(string url, string logoPath, int pixel) { return QRCoderHelper.GetLogoQRCode(url, logoPath, pixel); }
在IIS里面正常，但是在docker里面就报错。
IIS里面swagger中显示该方法返回的是：
"System.Drawing.Bitmap"
-------------
暂时改为：
public FileResult GetPTQRCode(QRCoderDto dto) { try { var bitmap = QRCoderHelper.GetPTQRCode(dto.Url, dto.Pixel); MemoryStream ms = new MemoryStream(); bitmap.Save(ms, ImageFormat.Jpeg); return new FileContentResult(ms.ToArray(), "image/png"); } catch (Exception) { throw new UserFriendlyException("二维码生成异常,请检查"); } }
然后在dockerfile中加入：
RUN mv /etc/apt/sources.list /etc/apt/sources.list.bak RUN echo "deb http://mirrors.163.com/debian/ jessie main non-free contrib" >> /etc/apt/sources.list RUN echo "deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list RUN echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list RUN echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list RUN apt-get update -y RUN apt-get install libgdiplus
netcore webapi 输出imges，在docker里面swagger报错
