head<T, K> function

Future<Result<K>> head<T, K>(
  1. String path, {
  2. Object? data,
  3. Map<String, dynamic>? queryParameters,
  4. Options? options,
  5. CancelToken? cancelToken,
  6. NetDecoder? httpDecode,
  7. NetConverter<K>? converter,
  8. T? decodeType,
})

Handy method to make http HEAD request, which is a alias of dio.fetch(RequestOptions). decodeType 为空返回原始数据

Implementation

Future<Result<K>> head<T, K>(
  String path, {
  Object? data,
  Map<String, dynamic>? queryParameters,
  Options? options,
  CancelToken? cancelToken,
  NetDecoder? httpDecode,
  NetConverter<K>? converter,
  T? decodeType,
}) async {
  assert(!(httpDecode != null && converter != null),
      'httpDecode和converter不能同时赋值，请删除一个');
  return await _execute(
    path,
    'HEAD',
    data: data,
    queryParameters: queryParameters,
    options: options,
    cancelToken: cancelToken,
    httpDecode: httpDecode,
    converter: converter,
    decodeType: decodeType,
  );
}
