深圳家装网站建设多少钱,燃灯seo,陕西省网站备案,佛山企业制作网站Flutter Dio如何自定义拦截异常
应用场景
我们一般会统一拦截DioExceptionType 如400#xff0c;403#xff0c;500 等错误 但有时候#xff0c;有个地方合并请求多个接口#xff0c;如果一个接口500#xff0c;那么导致其他请求不在执行#xff0c;因为统一拦截了500403500 等错误 但有时候有个地方合并请求多个接口如果一个接口500那么导致其他请求不在执行因为统一拦截了500 修改方法在请求时加一个Header 如isIntercep 字段在Dio onError 时 解出这个Header来如有这个字段返回如下就是不拦截这样的话只是这个接口返回数据错误不影响其他接口执行 handler.resolve(ResponseMapString, dynamic(requestOptions: err.requestOptions,statusCode: 200,data: {},),///请求公共参数拦截器
