Flutter Dio 源码 之 POST

9 min read
/// Handy method to make http POST request, which is a alias of  [BaseDio.requestOptions].
  @override
  Future<Response<T>> post<T>(
    String path, {
    data,
    Map<String, dynamic>? queryParameters,
    Options? options,
    CancelToken? cancelToken,
    ProgressCallback? onSendProgress,
    ProgressCallback? onReceiveProgress,
  }) {
    return request<T>(
      path,
      data: data,
      options: checkOptions('POST', options),
      queryParameters: queryParameters,
      cancelToken: cancelToken,
      onSendProgress: onSendProgress,
      onReceiveProgress: onReceiveProgress,
    );
  }

dio 本身提供了get 、post 、put 、delete 等一系列 http 请求方法，但是通过源码发现最终这些方法都是调用的 request 的方法实现的
