python - 使用 Pyramid 通过电子邮件发送从 POST 请求上传的文件

Question

我有一个 Angular 应用程序，它通过 POST 将文件上传到由 Pyramid/Python 处理的端点:

@Component({
   selector: 'app-application',
   templateUrl: 'app.application.html'
   })
export class ApplicationComponent {
   public uploader: FileUploader = new FileUploader({
   url: MyEndPoint
   });

还有我的 Pyramid 服务器:

@application.post()
def job_application(request):

    request.response.headerlist.extend(
        (
            ('Access-Control-Allow-Origin', AngularClient),
            ('Content-Type', 'application/json'),
            ('Access-Control-Allow-Credentials', 'true'),
            ('Allow', 'GET, POST')
        )
    )


    mailer = Mailer(host="smtp.gmail.com",
        port="465", username="makeemup@gmail.com", password="password", ssl=True)
message = Message(subject="It works!",
                  sender="makeemup@gmail.com",
                  recipients=["makeemup@gmail.com"],
                  body="hello"
                  )

if request.POST:

    attachment = Attachment("photo.doc", "doc/docx", str(request.body))
    message.attach(attachment)

    mailer.send_immediately(message, fail_silently=True)

return request.response

当我尝试将上传的文件附加到电子邮件时，WebKitFormBoundary 标记会附加到文件的页眉和页脚，并以字节代码返回内容。如何通过 Pyramid 服务器将实际上传的文件附加到电子邮件地址？

Answer 1

听起来发生的事情是您将 POST 请求的实际正文附加到文件本身，这就是为什么 WebKitFormBoundary 标记出现在您的文件中。

因此，首先您需要访问您想要的特定内容，该内容存储在 MultiDict 对象中，并且可以像普通字典一样访问。

然后我会将这些内容写入某处，比如您的/tmp/目录，特别是如果您是 UNIX 用户。然后从此文件路径将电子邮件附加到 Pyramids 邮件程序。

if request.POST:

    new_file = request.POST['uploadFile'].filename
    input_file = request.POST['uploadFile'].file
    file_path = os.path.join('/tmp', '%s.doc' % uuid.uuid4())
    temp_file_path = file_path + '~'


    input_file.seek(0)
    with open(temp_file_path, 'wb') as output_file:
        shutil.copyfileobj(input_file, output_file)

    os.rename(temp_file_path, file_path)
    data = open(file_path, 'rb').read()
    mr_mime = mimetypes.guess_type(file_path)[0]

    attachment = Attachment(new_file, mr_mime, data)
    message.attach(attachment)
    mailer.send_immediately(message, fail_silently=True)

希望这有帮助!
