@app.route('/', methods=['GET'])
def hello():
return 'hello'
@app.route('/a', methods=['GET'])
def a():
return 'a'

print(view_func_filename_linenum(get_view_func('/a')))
print(get_view_func_location_from_path('/a', 'post'))
3. 测试执行
$ python3 get_view.py
function: hello -> /mnt/d/luyangong/tmp/app.py: line 8
function: a -> /mnt/d/luyangong/tmp/app.py: line 12
function: b -> /mnt/d/luyangong/tmp/app.py: line 16
代码在 Python 3.8.5 Flask 1.1.2 Werkzeug 1.0.1 环境下测试通过。
