如何在Interceptorwrapper中传递onRequest

发布于 2025-01-14 17:24:12 字数 605 浏览 5 评论 0原文

requestInterceptor(RequestOptions options) async {

options.headers["Content-Type"] = "application/x-www-form-urlencoded";
return options;

在此

dio.interceptors.add(
  InterceptorsWrapper(
    onRequest: (RequestOptions options) => requestInterceptor(options),
  ),
);

之前工作正常，但现在错误出现为错误：参数类型“dynamic Function(RequestOptions)”无法分配给参数类型“void Function(RequestOptions, RequestInterceptorHandler)” 如果我在函数中添加处理程序错误，我必须做什么：无法将参数类型“dynamic Function(RequestOptions)”分配给参数类型“void Function(RequestOptions, RequestInterceptorHandler)”，它也给出了如何解决这个问题请帮忙

原文

requestInterceptor(RequestOptions options) async {

options.headers["Content-Type"] = "application/x-www-form-urlencoded";
return options;

}

dio.interceptors.add(
  InterceptorsWrapper(
    onRequest: (RequestOptions options) => requestInterceptor(options),
  ),
);

before this was working fine but now the error is coming as error: The argument type 'dynamic Function(RequestOptions)' can't be assigned to the parameter type 'void Function(RequestOptions, RequestInterceptorHandler)'
what I have to do if I add handler in the functions error: The argument type 'dynamic Function(RequestOptions)' can't be assigned to the parameter type 'void Function(RequestOptions, RequestInterceptorHandler)' its too gives how to solve this
please help

尝试在 onRequest 中使用 RequestInterceptorHandler 并将选项发送（下一步）到处理程序。

dio.interceptors.add(InterceptorsWrapper(
     onRequest: (RequestOptions options, RequestInterceptorHandler handler) async {
        options.headers["Content-Type"] = "application/x-www-form-urlencoded";
        return handler.next(options);
     }
));

Try to use RequestInterceptorHandler in onRequest and send (next) the option to the hander.

dio.interceptors.add(InterceptorsWrapper(
     onRequest: (RequestOptions options, RequestInterceptorHandler handler) async {
        options.headers["Content-Type"] = "application/x-www-form-urlencoded";
        return handler.next(options);
     }
));
