CKEditor下載地址:https://ckeditor.com/ckeditor-4/download/
訪問CKeditor官方網站,進入下載頁面,選擇Standard Package(一般情況下功能足夠用了),如果你想嘗試更多的功能,可以選擇下載Full Package。
下載好CKeditor之後,解壓到Flask專案static/ckeditor目錄即可。
在Flask專案中整合CKEditor:
- 在
<scripts>
標籤中匯入CKEditor - 使用
CKEDITOR.replace()
把現存的<textarea>
替換成CKEditor
程式碼如下:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
{# 引入CKEditor#}
<script type="text/javascript" src="../static/js/ckeditor/ckeditor.js"></script>
</head>
<body>
<form method="post" action="{{ url_for('ckupload') }} " enctype="multipart/form-data">
<input type="text" name="subject" placeholder="主題">
<textarea name="content" id="content" placeholder="內容"></textarea>
<input type="submit" value="立即釋出">
{# 替換textarea#}
<script type="text/javascript" >
CKEDITOR.replace('content', {
{# 開啟上傳功能,配置上傳路徑#}
filebrowserUploadUrl: '/ckupload/',
});
</script>
</form>
</body>
</html>
Flask處理上傳請求:
CKEditor上傳功能是統一的介面,即一個介面可以處理圖片上傳、檔案上傳、Flash上傳。先來看看程式碼:
from flask import Flask, render_template, request, make_response, url_for
from flask_script import Manager
import datetime
import os
import random
app = Flask(__name__)
manager = Manager(app)
def gen_rnd_filename():
filename_prefix = datetime.datetime.now().strftime('%Y%m%d%H%M%S')
return '%s%s' % (filename_prefix, str(random.randrange(1000, 10000)))
@app.route('/ckupload/', methods=['POST'])
def ckupload():
"""CKEditor file upload"""
error = ''
url = ''
callback = request.args.get("CKEditorFuncNum")
if request.method == 'POST' and 'upload' in request.files:
fileobj = request.files['upload']
fname, fext = os.path.splitext(fileobj.filename)
rnd_name = '%s%s' % (gen_rnd_filename(), fext)
filepath = os.path.join(app.static_folder, 'upload', rnd_name)
# 檢查路徑是否存在,不存在則建立
dirname = os.path.dirname(filepath)
if not os.path.exists(dirname):
try:
os.makedirs(dirname)
except:
error = 'ERROR_CREATE_DIR'
elif not os.access(dirname, os.W_OK):
error = 'ERROR_DIR_NOT_WRITEABLE'
if not error:
fileobj.save(filepath)
url = url_for('static', filename='%s/%s' % ('upload', rnd_name))
else:
error = 'post error'
res = """
<script type="text/javascript">
window.parent.CKEDITOR.tools.callFunction(%s, '%s', '%s');
</script>
""" % (callback, url, error)
response = make_response(res)
response.headers["Content-Type"] = "text/html"
return response
@app.route('/', methods=['POST', 'GET'])
def index():
return render_template('index.html')
if __name__ == '__main__':
manager.run()
再去看自己專案的目錄,就可以找到/upload
底下已經有自己上傳的圖片了。
