trycatch DioError的时候控制台会输出一些错误内容

Question

/// Dio适配器

class DioAdapter extends HiNetAdapter {

@override

Future<HiNetResponse<T>> send<T>(BaseRequest request) async {

var response, options = Options(headers: request.header);

var error;

try {

if (request.httpMethod() == HttpMethod.GET) {

response = await Dio().get(request.url(), options: options);

} else if (request.httpMethod() == HttpMethod.POST) {

response = await Dio()

.post(request.url(), data: request.params, options: options);

} else if (request.httpMethod() == HttpMethod.PUT) {

response = await Dio()

.put(request.url(), data: request.params, options: options);

} else if (request.httpMethod() == HttpMethod.DELETE) {

response = await Dio()

.delete(request.url(), data: request.params, options: options);

}

} on DioError catch (e) {

error = e;

response = e.response;

}

if (error != null) {

throw HiNetError(response?.statusCode ?? -1, error.toString(),

data: buildRes(response, request));

}

return buildRes(response, request);

}

  

/// 构建HiNetResponse

HiNetResponse buildRes(response, BaseRequest request) {

return HiNetResponse(

data: response.data,

request: request,

statusCode: response.statusCode,

statusMessage: response.statusMessage,

extra: response);

}

}

Future<dynamic> send<T>(BaseRequest request) async {

/// 使用Dio发送请求

HiNetAdapter adapter = DioAdapter();

return adapter.send(request);

}

多出一部分错误信息，且没办法捕捉到，dio版本是：dio: ^4.0.0

错误已经被DioAdapter中的

} on DioError catch (e) {

error = e;

response = e.response;

}

捕获了，然后被HiNet的  printLog(e);打印出来了。
