我最近开始学习 Flask，遇到了一个问题，当 1 个 html 文件有 2 个可以提交的表单时发生。当只有一种形式时，不会发生此问题。
这是我的包含flask的python文件：
from flask import Flask, request, render_template
app = Flask(__name__)
app.secret_key = 'secretkry'
@app.route("/", methods=["GET", "POST"])
def index():
if request.method == "POST":
if request.form["form_button_1"]:
return render_template('index.html', test_id="pressed form nr 1")
if request.form["form_button_2"]:
return render_template('index.html', test_id="pressed form nr 2")
return render_template('index.html', test_id="hasnt yet pressed form button")
if __name__ == '__main__':
app.run(port=44444)
这是我的index.html 文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="#" method="post">
<button name="form_button_1" type="submit" value="random_value1">form button 1</button>
</form>
<br>
<form action="#" method="post">
<button name="form_button_2" type="submit" value="random_value2">form button 2</button>
</form>
<p>{{test_id}}</p>
</body>
</html>
当我运行此命令时，我收到错误：400 错误请求。当我在 index.html 中只有 1 个表单时，不会发生这种情况 （index.html 看起来像这样）
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="#" method="post">
<button name="form_button_1" type="submit" value="random_value1">form button 1</button>
</form>
<br>
<p>{{test_id}}</p>
</body>
</html>
包含flask的python文件看起来像这样
from flask import Flask, request, render_template
app = Flask(__name__)
app.secret_key = 'secretkry'
@app.route("/", methods=["GET", "POST"])
def index():
if request.method == "POST":
if request.form["form_button_1"]:
return render_template('index.html', test_id="pressed form nr 1")
return render_template('index.html', test_id="hasnt yet pressed form button")
if __name__ == '__main__':
app.run(port=44444)
同样，第一个示例不起作用，但第二个示例（只有 1 个表单）起作用。 我想知道当存在 2 个表单时如何提交单击的表单。我使用的是 Kali Linux，如果这有什么不同的话。预先感谢
request.form@app.route("/", methods=["GET", "POST"])
def index():
if request.method == "POST":
if "form_button_1" in request.form:
return render_template('index.html', test_id="pressed form nr 1")
elif "form_button_2" in request.form:
return render_template('index.html', test_id="pressed form nr 2")
return render_template('index.html', test_id="hasnt yet pressed form button")
另一种选择是为按钮指定相同的名称，并检查值：
<form action="#" method="post">
<button name="form_button" type="submit" value="random_value1">form button 1</button>
</form>
<br>
<form action="#" method="post">
<button name="form_button" type="submit" value="random_value2">form button 2</button>
</form>
然后
@app.route("/", methods=["GET", "POST"])
def index():
if request.method == "POST":
if request.form["form_button"] == "random_value1":
return render_template('index.html', test_id="pressed form nr 1")
elif request.form["form_button"] == "random_value2":
return render_template('index.html', test_id="pressed form nr 2")
return render_template('index.html', test_id="hasnt yet pressed form button")
