Question

任何有关清洁解决方案的建议都将受到赞赏。

我正在尝试向现有应用添加一些静态文件，已经设置了包含其他文件的静态文件夹。我想基于列表定义几个路由，目标是能够轻松添加文件。

问题是我收到此而不是工作程序，未正确检测到“端点功能”。

输出：

public class PERSOON{
    public DateTime gebd {get;set;}
}

代码：

 {'/file1.js': <function func at 0x10aedfed8>, '/file2.js': <function func at 0x10aeea050>}
 {'/file1.js': <function func at 0x10aedfed8>, '/file2.js': <function func at 0x10aeea050>}

要投放的示例文件：

from flask import Flask
app = Flask(__name__)

def gen_serv_dep(path):
    fp = 'ui' + path  # path always starts with /
    with open(fp) as f:
        content = f.read()
    if path.endswith('.css'):
        mime = "text/css"
    elif path.endswith('.js'):
        mime = "text/javascript"
    else:
        mime = "text"
    def func():
        #this.__name__ = path  # doesn't change anything
        return Response(response=content, status=200, mimetype=mime)
    return func

deps = ['/file1.js', '/file2.js']
app.serv_deps = {}
for d in deps:
    app.serv_deps[d] = gen_serv_dep(d)
for d in deps:
    print(app.serv_deps)
app.add_url_rule(d, '', app.serv_deps[d])

@app.route('/')
def hello_world():
    return 'Hello, World!'

“因为您在for循环中多次将空字符串传递给add_url_rule。每次都选择一个唯一的名称。” - 大卫

这很好用

for d in deps:
    app.add_url_rule(d, d, app.serv_deps[d])

由于
