python flask在html页面上显示图像 [英] python flask display image on a html page
问题描述
我正在尝试传递图像的文件名并在模板上呈现它,
虽然我传递的实际名称没有显示在页面上
@ app.route('/',methods = ['GET','POST'])
@ app.route('/ start',methods = ['GET','POST'])
def start():
person_to_show ='tim'
profilepic_filename = os.path.join(people_dir,person_to_show,img.jpg)
返回render_template('start.html',profilepic_filename = profilepic_filename)
例如:profilepic_filename = /data/tim/img.jpg
我试过了
{{profilepic_filename}}
< ; img src ={{url_for('data',filename ='tim / img.jpg')}}>< / img>
我也试过
< img src ={{profilepic_filename}}>< / img>
两者都不起作用
我在 static
文件夹中创建了 people_photo
,并放置了一个名为<$ c $的图片C> shovon.jpg 。从 application.py
我将图像作为变量传递给模板,并在模板中使用 img
标记显示它。 / p>
在 application.py
:
来自flask进口Flask,render_template,request,url_for
import os
PEOPLE_FOLDER = os.path.join('static','people_photo')
app = Flask(__ name__)
app.config ['UPLOAD_FOLDER'] = PEOPLE_FOLDER
@ app.route('/')
@ app.route( '/ index')
def show_index():
full_filename = os.path.join(app.config ['UPLOAD_FOLDER'],'shovon.jpg')
返回render_template(index .html,user_image = full_filename)
在 index.html
:
<!DOCTYPE html>
< html>
< head>
< title> Index< / title>
< / head>
< body>
< img src ={{user_image}}alt =用户图片>
< / body>
< / html>
输出:
I am trying to pass a filename of an image and render it on a template, Although I am passing the actual name through it does not display on the page
@app.route('/', methods=['GET','POST'])
@app.route('/start', methods=['GET','POST'])
def start():
person_to_show = 'tim'
profilepic_filename = os.path.join(people_dir, person_to_show, "img.jpg")
return render_template('start.html',profilepic_filename =profilepic_filename )
For example: profilepic_filename = /data/tim/img.jpg I have tried
{{profilepic_filename}}
<img src="{{ url_for('data', filename='tim/img.jpg') }}"></img>
And I have also tried
<img src="{{profilepic_filename}}"></img>
Neither of which worked
I have created people_photo
in static
folder and placed an image named shovon.jpg
. From the application.py
I passed the image as variable to template and showed it using img
tag in the template.
In application.py
:
from flask import Flask, render_template, request, url_for
import os
PEOPLE_FOLDER = os.path.join('static', 'people_photo')
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = PEOPLE_FOLDER
@app.route('/')
@app.route('/index')
def show_index():
full_filename = os.path.join(app.config['UPLOAD_FOLDER'], 'shovon.jpg')
return render_template("index.html", user_image = full_filename)
In index.html
:
<!DOCTYPE html>
<html>
<head>
<title>Index</title>
</head>
<body>
<img src="{{ user_image }}" alt="User Image">
</body>
</html>
