免費的json基站定位接口

數據提供網站：http://www.minigps.net

接口使用和google以前的loc json一樣：

Request body

The request body must be formatted as JSON. The following fields are supported, and all fields are optional:

• homeMobileCountryCode: The mobile country code (MCC) for the device's home network.
• homeMobileNetworkCode: The mobile network code (MNC) for the device's home network.
• radioType: The mobile radio type. Supported values are gsm, cdma, and wcdma.
• carrier: The carrier name.
• cellTowers: An array of cell tower objects. See the Cell Tower Objects section below.
• wifi_access_points: An array of WiFi access point objects. See the WiFi Access Point Objects section below.

{  
  "homeMobileCountryCode": 310,  
  "homeMobileNetworkCode": 410,  
  "radioType": "gsm",  
  "carrier": "Vodafone",  
  "cellTowers": [  
    // See the Cell Tower Objects section below.  
  ],  
  "wifiAccessPoints": [  
    // See the WiFi Access Point Objects section below.  
  ]  
} 

Cell tower objects

The request body's cellTowers array contains zero or more cell tower objects. All fields are optional.

• cellId: Unique identifier of the cell. On GSM, this is the Cell ID (CID); CDMA networks use the Base Station ID (BID).
• locationAreaCode: The Location Area Code (LAC) for GSM networks; CDMA networks use Network ID (NID).
• mobileCountryCode: The cell tower's Mobile Country Code (MCC).
• mobileNetworkCode: The cell tower's Mobile Network Code. This is the MNC for GSM, or the System ID (SID) for CDMA.
• age: The number of milliseconds since this cell was primary. If age is 0, the cellId represents a current measurement.
• signalStrength: Radio signal strength measured in dBm.
• timingAdvance: The timing advance value.

An example cell tower object is below.

{  
  "cellId": 42,  
  "locationAreaCode": 415,  
  "mobileCountryCode": 310,  
  "mobileNetworkCode": 410,  
  "age": 0,  
  "signalStrength": -60,  
  "timingAdvance": 5555  
}
