400错误请求python烧瓶
[英]400 Bad Request python flask
问题描述
Hi I'm new to python flask, i have what seems a simple issue of a 400 bad request error, that should be due to having wrongly named variables in form when trying to pass them to a function in python flask.
嗨，我是 python flask 的新手，我有一个看起来很简单的 400 错误请求错误问题，这应该是由于在尝试将它们传递给 python flask 中的函数时，表单中的变量命名错误。 I have done some research but i still can't figure out where i go wrong with this code, any help would be really appreciated.我已经做了一些研究，但我仍然无法弄清楚这段代码哪里出了问题，任何帮助都将不胜感激。 Here is the code for the html form这是html表单的代码
<html>
<body>
<h1>Add a Munroe to your list</h1>
<form action = "{{ url_for('addmunro') }}" method="POST"
enctype = "multipart/form-data">
Name<br>
<input type="text" name="mnName"/><br>
Description<br>
<input type="text" name="mnDesc"/><br>
Region<br>
<input type="text" name="mnRegion"/><br>
Height<br>
<input type="text" name="mnHeight"/><br>
Walk date<br>
<input type="text" name="mnDate"/><br>
Walk image<br>
<input type="text" name="mnImage"/><br>
<br>
<br>
<input type="submit" name="add-munro.html" value = "ADD MUNRO"/>
</form>
</body>
</html>
And here is the code for the python flask application这是python烧瓶应用程序的代码
from flask import Flask, render_template, url_for, redirect, json, request
app = Flask(__name__)
@app.route('/add-munro.html', methods=['GET'])
def addmunro():
#Create an empty list
mnList={}
#Create a munro dictionary
munro = {'name':request.form['mnName'],
'desc':request.form['mnDesc'],
'region':request.form['mnRegion'],
'height':request.form['mnHeight'],
'date':request.form['mnDate'],
'image':request.form['mnImage']}
#the munro dictionary is added to mnList
#mnList.append(munro)
return render_template('add-munro.html')
if __name__ == "__main__":
app.run(host = '0.0.0.0', debug = True)

You are making a POST request in your form, but only allow the GET method in your app route.您正在表单中发出POST请求，但只允许在您的应用程序路由中使用GET方法。 Change @app.route('/add-munro.html', methods=['GET']) to @app.route('/add-munro.html', methods=['POST']) .将@app.route('/add-munro.html', methods=['GET'])更改为@app.route('/add-munro.html', methods=['POST']) 。

There are several mistakes:有几个错误：
- You are making POST request but handling only GET request您正在发出 POST 请求但仅处理 GET 请求
- .html is not needed in routing路由中不需要 .html
- munro object is not passed to the template munro 对象未传递给模板
I have updated these and now it's good to go:我已经更新了这些，现在可以开始了：
application.py
from flask import Flask, render_template, request, url_for
app = Flask(__name__)
@app.route('/add-munro', methods=['GET','POST'])
def addmunro():
if request.method == "POST":
#Create an empty list
mnList={}
#Create a munro dictionary
munro = {'name':request.form['mnName'],
'desc':request.form['mnDesc'],
'region':request.form['mnRegion'],
'height':request.form['mnHeight'],
'date':request.form['mnDate'],
'image':request.form['mnImage']}
return render_template('add-munro.html', munro=munro)
else:
return render_template('add-munro.html')
if __name__ == '__main__':
app.run(debug=True)
add-munro.html
<html>
<body>
{% if munro is defined -%}
<h3>
Name: {{ munro.name }}
</h3>
<h3>
Description: {{ munro.desc }}
</h3>
<h3>
Region: {{ munro.region }}
</h3>
<h3>
Height: {{ munro.height }}
</h3>
{%- endif %}
<h1>Add a Munroe to your list</h1>
<form action = "{{ url_for('addmunro') }}" method="POST"
enctype = "multipart/form-data">
Name<br>
<input type="text" name="mnName"/><br>
Description<br>
<input type="text" name="mnDesc"/><br>
Region<br>
<input type="text" name="mnRegion"/><br>
Height<br>
<input type="text" name="mnHeight"/><br>
Walk date<br>
<input type="text" name="mnDate"/><br>
Walk image<br>
<input type="text" name="mnImage"/><br>
<br>
<br>
<input type="submit" value = "ADD MUNRO"/>
</form>
</body>
</html>
