Google Geolocation API is always returning the same location regardless of cellTower specified

问题

I'm using the Google Geolocation API to approximate location based on cell towers that are visible. However, I always get the same location as the result.

Using the following body:

{
    "considerIp": false,
    "radioType": "lte",
    "cellTowers": [{
        "signalStrength": -78,
        "cellId": 133978007,
        "mobileNetworkCode": 410,
        "mobileCountryCode": 310,
        "locationAreaCode": 27196
    }]
}

Produces the following result: {"location": {"lat": 31.968598800000002, "lng": -99.9018131}, "accuracy": 1457406}

The actual location of that tower/cell is approx (32.783062, 96.795769). In fact, the cell tower specified is take directly from OpenCellID's database (opencellid.org)

If I then select a tower somewhere else (e.g. Palo Alto)

{
    "considerIp": false,
    "radioType": "lte",
    "cellTowers": [{
        "signalStrength": -78,
        "cellId": 84785686,
        "mobileNetworkCode": 480,
        "mobileCountryCode": 311,
        "locationAreaCode": 7943
    }]
}

The response is: {"location": {"lat": 31.968598800000002, "lng": -99.9018131}, "accuracy": 1457406} which is exactly the same.

If I can my public IP (via changing VPN end-point location) the results DO change. Using the same Palo Alto query but changing from a Texas to Chicago end-node my result changes to: {"location": {"lat": 37.09024, "lng": -95.712891}, "accuracy": 1488703}

It looks like the considerIp=false argument is being ignored and that is only being used instead of the provided cell tower.

Any ideas how to fix this? Thanks!

回答1:

I figured it out. Apparently if the Content-Type is not being explicitly set to application/json then the body is silently ignored and only the local IP is considered.

I would like to request that Google updates the API response body to include something to that effect.
