我正在尝试运行这个Flask项目,认为它不起作用。有谁知道为什么?
.py文件:
from flask import Flask, render_template
app = Flask(__name__)
@app.route("/")
def hoofdpagina():
return render_template("afvink2.html")
if __name__ == '__main__':
app.run()
HTML文件:
<!DOCTYPE html>
<html>
<body onunload="Reset()" style="background-color:Pink;">
<head>
<title>Messenger </title>
</head>
<h3>Messenger</h3>
Messagebox:<br> <textarea id="chatbox" cols="50" rows="5"></textarea> <br><br>
<br><input type="text" id="P1" value="ADI" ><input type="text" id="first"><button onclick="B1Function()">Send</button><br><br>
<br><input type="text" id="P2" value="JS" > <input type="text" id="second"><button onclick="B2Function()">Send</button>
<script>
function B1Function() {
document.getElementById("chatbox").value += document.getElementById("P1").value ;
document.getElementById("chatbox").value += ": " ;
document.getElementById("chatbox").value += document.getElementById("first").value ;
document.getElementById("chatbox").value += "\r"
document.getElementById("first").value = ""
}
function B2Function() {
document.getElementById("chatbox").value += document.getElementById("P2").value ;
document.getElementById("chatbox").value += ": " ;
document.getElementById("chatbox").value += document.getElementById("second").value ;
document.getElementById("chatbox").value += "\r"
document.getElementById("second").value = ""
}
function Reset() {
document.getElementById("Berichtenbox").value = ""
document.getElementById("first").value = ""
document.getElementById("second").value = ""
}
</script>
</body>
</html>
错误:
C:\...\...\...\

有谁知道如何解决这个问题?谢谢!

您的项目结构应为此。
├── app.py
└── templates
└── afvink2.html
默认情况下, render_template
方法会查看模板目录。
您还可以将模板目录配置为视图或公开
简单地提到烧瓶中的参数
app = Flask(__name__, template_folder="views")
app = Flask(__name__, template_folder="path/to/whatever")
请检查配置瓶提供的内容。 他们的documentation非常整洁。

Flask将在“templates”目录中查找模板。将您的html模板移动到模板目录中。它应该工作
