文件上传邮件发送

一、原生文件上传

form.html

  <img src="/UploadFiles/2021-04-08/17.jpg') }}">

manage.py




#文件上传的视图函数
@app.route('/upload/',methods=['GET','POST'])
def icon():
  img_name = None
  if request.method == 'POST' and 'file' in request.files:
    # return '有文件上传了'
    file = request.files.get('file')
    filename = file.filename #拿到文件名称
    #图片上传保存的路径
    imgPath = os.path.join(os.getcwd(), 'static/upload/'+filename)
    file.save(imgPath)
    img_name = filename
  return render_template('user/change_icon.html',img_name=img_name)



使用wtf和bootstrap渲染文件上传




from flask import Flask,render_template,request
from flask_script import Manager
from flask_wtf import FlaskForm
from flask_wtf.file import FileField,FileAllowed,FileRequired
from wtforms import SubmitField
from flask_uploads import UploadSet,patch_request_class,configure_uploads,IMAGES
from flask_bootstrap import Bootstrap
import os
from PIL import Image

app = Flask(__name__)
app.config['MAX_CONTENT_LENGTH'] = 1024*1024*64
app.config['SECRET_KEY'] = 'abcdef'
app.config['UPLOADED_PHOTOS_DEST'] = os.path.join(os.getcwd(),'static/upload')
bootstrap = Bootstrap(app)
file = UploadSet('photos',IMAGES)
configure_uploads(app,file)
patch_request_class(app,size=None)
manager = Manager(app)

#自定义一个文件上传的表单类
class File(FlaskForm):
  photos = FileField('修改头像',validators=[FileRequired(message='文件不能为空'),FileAllowed(file,message='该文件类型不允许上传')])
  submit = SubmitField('提交')

@app.route('/')
def index():
  return render_template('index.html')

#生成随机的图片名称
def random_name(suffix,length=32):
  import string,random
  myStr = string.ascii_letters + '0123456789'
  return ''.join(random.choice(myStr) for i in range(length))+suffix

@app.route('/upload/',methods=['GET','POST'])
def icon():
  form = File()
  img_url = None
  if form.validate_on_submit():
    data = request.files.get('photos')
    suffix = os.path.splitext(data.filename)[-1]
    newName = random_name(suffix)
    file.save(data,name=newName)
    img_url = file.url(newName)

    img = Image.open(os.path.join(app.config['UPLOADED_PHOTOS_DEST'],newName))
    print(img.size) # 获取图片大小
    # 设置尺寸
    img.thumbnail((128, 128)) # 当前缩放不是等比缩放 变成等比缩放
    img.save(os.path.join(app.config['UPLOADED_PHOTOS_DEST'],'s_'+newName))
  return render_template('user/wtf-uplods.html',form=form,img_url=img_url)

if __name__ == '__main__':
  manager.run()




模板中的代码




from flask import Flask,render_template,request
from flask_script import Manager
from flask_wtf import FlaskForm
from flask_wtf.file import FileField,FileAllowed,FileRequired
from wtforms import SubmitField
from flask_uploads import UploadSet,patch_request_class,configure_uploads,IMAGES
from flask_bootstrap import Bootstrap
import os
from PIL import Image

app = Flask(__name__)
app.config['MAX_CONTENT_LENGTH'] = 1024*1024*64
app.config['SECRET_KEY'] = 'abcdef'
app.config['UPLOADED_PHOTOS_DEST'] = os.path.join(os.getcwd(),'static/upload')
bootstrap = Bootstrap(app)
file = UploadSet('photos',IMAGES)
configure_uploads(app,file)
patch_request_class(app,size=None)
manager = Manager(app)

#自定义一个文件上传的表单类
class File(FlaskForm):
  photos = FileField('修改头像',validators=[FileRequired(message='文件不能为空'),FileAllowed(file,message='该文件类型不允许上传')])
  submit = SubmitField('提交')

@app.route('/')
def index():
  return render_template('index.html')

#生成随机的图片名称
def random_name(suffix,length=32):
  import string,random
  myStr = string.ascii_letters + '0123456789'
  return ''.join(random.choice(myStr) for i in range(length))+suffix

@app.route('/upload/',methods=['GET','POST'])
def icon():
  form = File()
  img_url = None
  if form.validate_on_submit():
    data = request.files.get('photos')
    suffix = os.path.splitext(data.filename)[-1]
    newName = random_name(suffix)
    file.save(data,name=newName)
    img_url = file.url(newName)

    img = Image.open(os.path.join(app.config['UPLOADED_PHOTOS_DEST'],newName))
    print(img.size) # 获取图片大小
    # 设置尺寸
    img.thumbnail((128, 128)) # 当前缩放不是等比缩放 变成等比缩放
    img.save(os.path.join(app.config['UPLOADED_PHOTOS_DEST'],'s_'+newName))
  return render_template('user/wtf-uplods.html',form=form,img_url=img_url)

if __name__ == '__main__':
  manager.run()




二、发送邮件 flask-mail




pip install flask-mail


设置临时环境变量


windows set 名=值
Ubuntu下 export 名=值


注意： 名和值都不用加引号
单线程发送邮件




from flask import Flask,render_template
from flask_script import Manager
from flask_mail import Mail,Message
import os

app = Flask(__name__)
app.config['MAIL_SERVER'] = 'smtp.163.com'
# 为了保密 将邮箱账号和授权码都加入到了临时环境变量中
app.config['MAIL_USERNAME'] = os.environ.get('MAIL_USERNAME')
app.config['MAIL_PASSWORD'] = os.environ.get('MAIL_PASSWORD')

mail = Mail(app)
manager = Manager(app)

@app.route('/send_mail/')
def send_mail():
  msg = Message(subject='大郎',recipients=['793390457@qq.com'],sender=app.config['MAIL_USERNAME'])
  msg.html = render_template('email/activate.html',username='大郎')
  mail.send(message=msg)
  return '发送邮件'

if __name__ == '__main__':
  manager.run()




异步发送邮件




from flask import Flask,render_template
from flask_script import Manager
from flask_mail import Mail,Message
import os
from threading import Thread

app = Flask(__name__)
app.config['MAIL_SERVER'] = 'smtp.163.com'
app.config['MAIL_USERNAME'] = os.environ.get('MAIL_USERNAME')
app.config['MAIL_PASSWORD'] = os.environ.get('MAIL_PASSWORD')

mail = Mail(app)
manager = Manager(app)

@app.route('/send_mail/')
def send_mail():
  msg = Message(subject='大郎',recipients=['793390457@qq.com'],sender=app.config['MAIL_USERNAME'])
  msg.html = render_template('email/activate.html',username='大郎')
  thr = Thread(target=async_send_mail,args=(msg,)) #创建线程 参数1为创建子线程 参数2为传递参数 类型为元组
  thr.start() #开启线程
  return '发送邮件'

def async_send_mail(msg):
  #开启程序上下文 把当前请求 作为同一个请求
  with app.app_context():
    mail.send(message=msg)

if __name__ == '__main__':
  manager.run()

稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！

昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
