新手，在用flask做一个小小的项目，遇到了难题，就是我后端往前端传值，从接口里获取的值传到前台却不显示，f12显示是有接收到的，但就是不忘页面上渲染，可如果我直接把值定死的话，就可以显示出来，这到底是是什么问题，求大佬帮忙
从接口接收值
后台代码：
from flask import Flask,render_template,request
import requests
app = Flask(__name__)
app.debug = True
key = "1ee7102878b94eb78ee10fa496729c10"
@app.route('/',methods=["GET","POST"])
def home():
province = request.form.get("province")
city = request.form.get("city")
data = {
"city": city,
"province": province
}
return render_template("home.html", **data)
if __name__ == '__main__':
app.run()
前台代码：
<div class="search">
<form action="/home" method="POST" id="form">
<input type="text" name="province" class="keywords" placeholder="输入要搜索的省">
<input type="text" name="city" class="keywords" placeholder="输入要搜索的市">
<button class="search-btn" type="submit"><span class="glyphicon glyphicon-search" aria-hidden="true"></span></button>
</form>
<span class="sm-title">{{ city }}</span>
<p class="city-search"><b>{{ province }}</b><span id="btn-search" class="glyphicon glyphicon-search" aria-hidden="true"></span></p>
</div>
运行结果：
f12：
自己设定值
后端代码：
from flask import Flask,render_template,request
import requests
app = Flask(__name__)
app.debug = True
key = "1ee7102878b94eb78ee10fa496729c10"
@app.route('/',methods=["GET","POST"])
def home():
province = "山西省"
city = "运城市"
data = {
"city": city,
"province": province
}
return render_template("home.html", **data)
if __name__ == '__main__':
app.run(debug=True)
前端代码无变化
运行结果：
