# ref:
from flask import Flask, abort, request, jsonify
import json
import time
app = Flask(__name__)
@app.route('/', methods=['GET'])
def get_task():
if not request.args or 'text' not in request.args:
return jsonify("{'err':'not found param: text'}")
else:
text = request.args['text']
r = "您輸入的文本是：" + text
# return jsonify("{'result':'"+r+"'}")
# return r
result = {}
result['result'] = r
result['time'] = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
return result
if __name__ == "__main__":
# 將host設置為0.0.0.0，則外網用戶也可以訪問到這個服務
app.run(host="0.0.0.0", port=5003, debug=True)
運行代碼之后，可以在瀏覽器訪問，端口號5003
后端2
上面的代碼一是只有get方法，二是在使用了python3.8之后，有些問題。
from flask import Flask, abort, request, jsonify, render_template
from flask_cors import CORS
import json
from snownlp.summary import textrank
import time
app = Flask(__name__)
CORS(app)
@app.route('/', methods=['get', 'post'])
def get_task():
if not request.values or 'text' not in request.values:
return jsonify("{'err':'not found param: text'}")
else:
text = request.args['text']
r = "您輸入的文本是：" + text
# return jsonify("{'result':'"+r+"'}")
# return r
result = {}
result['result'] = r
result['time'] = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
return result
if __name__ == "__main__":
# 將host設置為0.0.0.0，則外網用戶也可以訪問到這個服務
app.run(host="0.0.0.0", port=5003, debug=True)
仍然可以使用瀏覽器通過get方法調用
前端頁面使用post方法調用
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title>我的頁面</title>
</head>
<body>
<div class="container" align="center">
<h1>頁面演示</h1>
<form action="http://localhost:5003/" method="post">
<textarea name="text" cols="90" rows="30" placeholder="請輸入.."></textarea>
<br><br><br>
<input type="submit" value="Submit" align="right"/>
</form>
</div>
</body>
</html>
