我需要使用Google API检查城市和州的特定组合是否正确。
到目前为止找到的方式
1。使用GeoCoding API ：
我们可以使用zipCode进行调用，它将返回一个JSON。有一个描述格式化地址的字段，其中包含城市，州，邮政编码，区域等。
http://maps.googleapis.com/maps/api/geocode/json?address=ZIPCODE&sensor=true
2。 ZIPtastic API
与上述类似，但会返回少量信息。
但现在我想没有ZIPCode。 [即]给出了城市和州，我需要使用API检查给定的组合是否正确。有什么方法吗？请提出一些想法。
编辑： 我需要检查给定的城市，州，国家，邮政编码是否正确。
http://maps.googleapis.com/maps/api/geocode/json?address=NY&address=10001&sensor=true&components=country:US
上述内容返回与
相同的结果http://maps.googleapis.com/maps/api/geocode/json?address=NY&address=10001&sensor=true&address=albanycomponents=country:US
Zipcode是10001，State是NY，City是Albany，Country是US。为什么它会返回相同的结果。我得到了正确的结果还是做了什么？
答案 0 :(得分：2)
您可以在GeoCoding API的address参数中使用您想要的内容，例如：
http://maps.googleapis.com/maps/api/geocode/json?address=Paris&sensor=true
我在这里得到的结果与地址Paris匹配：法国巴黎，德克萨斯州巴黎等。
因此，您可以使用它输入您的城市并检查状态是否有效。为此，请使用以下补码限制您的搜索到美国：components=country:US
示例：http://maps.googleapis.com/maps/api/geocode/json?address=Paris&sensor=true&components=country:US
结果：

然后你解析JSON并且能够找到你想要的东西，这里有administrative_area_level_1字段用于状态！
修改：此外，您还可以指定您的搜索仅在locality字段上：
http://maps.googleapis.com/maps/api/geocode/json?sensor=true&components=country:US|locality:Paris过滤来自其他文件中名称Paris的可能结果
