查询自动补全服务可用于在输入基于文本的地理搜索时提供查询预测,在您输入内容时返回建议的查询。
查询自动补全请求
查询自动补全服务是 Places API 的一部分,与 Places API 共享 API 密钥和配额。
查询自动补全服务允许您向应用中添加实时地理位置查询预测结果。用户无需输入具体位置,只需输入分类搜索(例如“北京烤鸭”),该服务即会返回与字符串匹配的建议查询列表作为响应。由于查询自动补全服务可以同时匹配完整字词和子字符串,因此应用可以将查询作为用户类型发送,以提供即时预测。
查询自动完成请求是一个 HTTP URL,其格式如下:
https://maps.googleapis.com/maps/api/place/queryautocomplete/output?parameters
其中,output
可以是 json
或 xml
。
您需要使用某些参数,才能发起查询自动补全请求。
根据网址的标准,所有参数均使用和号 (&
) 字符分隔。下面枚举了各个参数及其可能的值。
Required parameters
input
The text string on which to search. The Place Autocomplete service will return candidate matches based on this string and order results based on their perceived relevance.
radius
Defines the distance (in meters) within which to return place results. You may bias results to a specified circle by passing a
location
and aradius
parameter. Doing so instructs the Places service to prefer showing results within that circle; results outside of the defined area may still be displayed.The radius will automatically be clamped to a maximum value depending on the type of search and other parameters.
- Autocomplete: 50,000 meters
-
Nearby Search:
- with
keyword
orname
: 50,000 meters -
without
keyword
orname
-
Up to 50,000 meters, adjusted dynamically based on area density,
independent of
rankby
parameter. -
When using
rankby=distance
, the radius parameter will not be accepted, and will result in anINVALID_REQUEST
.
-
Up to 50,000 meters, adjusted dynamically based on area density,
independent of
- with
- Query Autocomplete: 50,000 meters
- Text Search: 50,000 meters
Optional parameters
language
The language in which to return results.
- See the list of supported languages. Google often updates the supported languages, so this list may not be exhaustive.
-
If
language
is not supplied, the API attempts to use the preferred language as specified in theAccept-Language
header. - The API does its best to provide a street address that is readable for both the user and locals. To achieve that goal, it returns street addresses in the local language, transliterated to a script readable by the user if necessary, observing the preferred language. All other addresses are returned in the preferred language. Address components are all returned in the same language, which is chosen from the first component.
- If a name is not available in the preferred language, the API uses the closest match.
- The preferred language has a small influence on the set of results that the API chooses to return, and the order in which they are returned. The geocoder interprets abbreviations differently depending on language, such as the abbreviations for street types, or synonyms that may be valid in one language but not in another. For example, utca and tér are synonyms for street in Hungarian.
location
The point around which to retrieve place information. This must be specified as
latitude,longitude
.Thelocation
parameter may be overriden if thequery
contains an explicit location such asMarket in Barcelona
. Using quotes around the query may also influence the weight given to thelocation
andradius
.offset
The position, in the input term, of the last character that the service uses to match predictions. For example, if the input is
Google
and the offset is 3, the service will match onGoo
. The string determined by the offset is matched against the first word in the input term only. For example, if the input term isGoogle abc
and the offset is 3, the service will attempt to match againstGoo abc
. If no offset is supplied, the service will use the whole term. The offset should generally be set to the position of the text caret.
