Flutter全局Http拦截器 [英] Flutter Global Http Interceptor

问题描述

我想知道是否可以在Flutter中使用全局HTTP拦截器在标头中附加令牌吗？我进行了很多搜索，找不到任何信息以及如何将其设置为全局信息。非常感谢！

I would like to know if it is possible to have a global HTTP interceptor to attach token in header for all requests in Flutter? I've searched a lot and couldn't find any information as where and how to set it up as globally. Thanks a lot!

推荐答案

使用 dio 包u可以做到：

Dio dio = Dio(BaseOptions(
 connectTimeout: 30000,
 baseUrl: 'your api',
 responseType: ResponseType.json,
 contentType: ContentType.json.toString(),
))
..interceptors.addAll(
[
  InterceptorsWrapper(onRequest: (RequestOptions requestOptions) {
    dio.interceptors.requestLock.lock();
    String token = ShareP.sharedPreferences.getString('token');
    if (token != null) {
      dio.options.headers[HttpHeaders.authorizationHeader] =
          'Bearer ' + token;
    }
    dio.interceptors.requestLock.unlock();
    return requestOptions;
  }),
  // other interceptor
 ],
);
