如何在Flask中调用Zerodha API

Question

我想调用 Zerodha API 来搜索仪器并添加到愿望清单，但是任何人都可以指导我如何让它在 Flask 应用程序中调用仪器搜索，因为 GUI 是 HTML 格式的，以及如何将其连接到 Flask 应用程序首先我做了Tkinter 中的 GUI，但现在我想使用 Flask 在 Web 应用程序中转换它。请指导。

提前致谢。

我正在分享我仅使用 Zerodha API 用 Python 制作的 Tkinter GUI 的代码。

def create_search_bar(self):
        search_frame = ttk.Frame(self.root)
        search_frame.pack(side=tk.LEFT, padx=0, pady=0, anchor='n')

        self.search_entry = ttk.Entry(search_frame, font=('Consolas', 12))
        self.search_entry.pack(side=tk.TOP, padx=0, pady=0)

        self.suggestion_listbox = tk.Listbox(search_frame, font=('Consolas', 12), height=15, width=35)
        self.suggestion_listbox.pack(side=tk.TOP, padx=0, pady=0)
        self.suggestion_listbox.bind('<ButtonRelease-1>', self.add_selected_instrument)

    def update_suggestions(self, event):
        query = self.search_entry.get().strip().upper()
        suggestions = [instrument for instrument in self.all_instruments if query in instrument.upper()]

        if query:
            self.suggestion_listbox.pack(side=tk.TOP, padx=0, pady=0)

            self.show_result(f"Selected Stock: {selected_stock}, Price: {price}")
            # Open details window
            self.show_instrument_details(selected_stock, price)

我该如何在 Flask 中调用它，请指导。

Zerodha 在这里给出了如何在 Flask 中使用 Zerodha API 的示例... https://github.com/zerodha/pykiteconnect/blob/master/examples/flask_app.py 看一下..可能会有所帮助...
