textSearch method

Future<SearchPoiResponse> textSearch({
  1. String? keywords,
  2. String? types,
  3. String? region,
  4. bool? cityLimit,
  5. String? showFields,
  6. int? pageSize,
  7. int? pageNum,
  8. String? output,
})

关键字搜索 必填: keyword或者types二选一 keywords: 地点关键字 types: 指定地点类型 region: 搜索区划 city_limit: 指定城市数据召回限制, 默认为false show_fields: 返回结果控制 page_size: 当前分页展示的数据条数，取值为1-25，默认为10 page_num: 请求第几分页，取值为1-100，默认为1 output: 返回结果格式类型，默认格式为json，目前只支持json格式

Implementation

Future<SearchPoiResponse> textSearch({
  String? keywords,
  String? types,
  String? region,
  bool? cityLimit,
  String? showFields,
  int? pageSize,
  int? pageNum,
  String? output,
}) async {
  assert(keywords != null || types != null);
  Uri uri = appendApiPath(this.uri, "/v5/place/text");
  final params = <String, dynamic>{};
  params['key'] = apiKey;
  if (keywords != null && keywords.isNotEmpty) params["keywords"] = keywords;
  if (types != null && types.isNotEmpty) params["types"] = types;
  if (region != null && region.isNotEmpty) params["region"] = region;
  if (cityLimit != null) params["city_limit"] = cityLimit;
  if (showFields != null && showFields.isNotEmpty) params["show_fields"] = showFields;
  if (pageSize != null && pageSize > 0) params["page_size"] = pageSize;
  if (pageNum != null && pageNum > 0) params["page_num"] = pageNum;
  if (output != null && output.isNotEmpty) params["output"] = output;
  if (secretKey != null) params["sig"] = generateSignature(params);
  final url = appendParameters(uri, params).toString();
  final response = await doGet(url, headers: apiHeaders);
  return SearchPoiResponse.fromJson(jsonDecode(response.body));
