@app.route('/diseases_bpnn', methods=["POST"]) def diseases_bp_app(): request = flask.request # 获取请求IP地址 if request.headers.getlist("X-Forwarded-For"): ip = request.headers.getlist("X-Forwarded-For")[-1] else: ip = request.remote_addr print(">>>>>>>>ip:{}<<<<<<<<<<".format(ip)) returnData = {} params = request.json input = diseases_preprocessing(params["input"]) pred = F.softmax(diseases_bpnn(torch.from_numpy(input).float()), dim=1)[0][1] returnData['prob'] = f'{pred:.4f}' return returnData 将这段代码的每个语句逐一讲解

这段代码是一个Flask应用程序路由器，使用POST请求访问/diseases_bpnn路径，并定义了名为diseases_bp_app的处理程序。其中，flask.request是从Flask框架导入的对象，用于处理HTTP请求。
