Python 字符串POST请求到烧瓶
我正在尝试使用Python 字符串POST请求到烧瓶,python,flask,Python,Flask,我正在尝试使用Flask实现一个简单的仪表板，它将： 使用“提交”按钮接受用户文本输入。将此用户输入发布到flask Flask接受此输入，对其执行一些操作，然后向另一个API发出GET请求 这个GET请求返回数据并以某种方式显示它（现在可以是console.log） 例如，使用星球大战API： 用户输入星球大战字符的名称（假定没有拼写错误） Flask读取此输入名称，并将其映射到ID号，因为接受ID号。向星球大战API发出GET请求，以获取完整的字符信息 现在，我们只需要console.log
Flaskconsole.logconsole.logfrom flask import Flask, jsonify, request, render_template

app = Flask(__name__)
@app.route("/")
def index():
return render_template('index.html')
@app.route("/form_example", methods=["GET", "POST"])
def form_example():
if request.method == "POST":
language = request.form("character_name")
starwars_dictionary = {"Luke Skywalker":"1", "C-3PO":"2", "R2-D2": "3"}
# starwars_dictionary is a dictionary with character_name:character_number key-value pairs.
# GET URL is of the form https://swapi.co/api/people/<character_number>
return render_template("index.html")

py到JS
样本输入
- 卢克·天行者
- C-3PO
- R2-D2
输入名称：
{{字符高度}}
/操作
需要更像：
<form method="POST" action="/form_example">
编辑：也就是说，您可以使用单一路由功能处理此问题：
<form method="POST" action="{{ url_for('form_example') }}">
@app.route("/", methods=["GET", "POST"])
def index():
if request.method == "POST":
language = request.form("character_name")
starwars_dictionary = {"Luke Skywalker":"1", "C-3PO":"2", "R2-D2": "3"}
# Logic to query remote API ges here.
else: # Assume method is GET
return render_template("index.html")
然后使表单操作{{url\u for（'index'）}}
