onRequest method
The callback will be executed before the request is initiated.
If you want to continue the request, call handler.next
.
If you want to complete the request with some custom data,
you can resolve a Response object with handler.resolve
.
If you want to complete the request with an error message,
you can reject a DioError object with handler.reject
.
Implementation
@override
void onRequest(RequestOptions options, RequestInterceptorHandler handler) {
var requestUrl = options.baseUrl + options.path;
var formData = options.data;
Map<String, dynamic> showInfo = {'Header信息': options.headers};
if (options.queryParameters.isNotEmpty) {
showInfo['query'] = options.queryParameters;
}
if (formData != null) {
showInfo['data'] = formData;
}
XLog.i(showInfo, '###${options.method}请求### $requestUrl');
return handler.next(options);
}
