request method

@Doc(message: "向服务器发起http请求") Future request({ bool showErrorMsg = true, String? loadingText, String contentType = "", Map<String, dynamic>? headers, bool showDefaultLoading = true, dynamic data, ResponseType? responseType, bool? nullParams, RequestEncoder? requestEncoder, DioStart? dioStart, bool? returnIsString, bool isFullUrl = false, })

isFullUrl - url传入的是否为完整的一个URL,如果为true,将忽略host
