Today, I would like to share with you the relevant knowledge about how WeChat Mini Programs API obtains the location. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Wx.getLocation (OBJECT)

Get the current geographic location and speed. This API cannot be called when the user leaves Mini Program; when the user clicks "Show at the top of chat", the API can continue to be called.

OBJECT parameter description:

The required parameter type indicates whether typeString returns gps coordinates by default "wgs84", and "gcj02" returns the coordinates available for wx.openLocation. SuccessFunction is a callback function successfully called by the API. For more information, please see the returned parameters. FailFunction No API calls failed callback function completeFunction No API calls the finished callback function (both successful and failed calls will be executed)

Success return parameter description:

Parameter description minimum version latitude latitude, floating point number, range is-90mm 90, negative number indicates south latitude longitude longitude, floating point number, range is-180mm 180. negative number indicates west longitude speed speed, floating point number, accuracy altitude height of unit m/saccuracy position, unit m1.2.0verticalAccuracy vertical precision, unit m (Android cannot be obtained, returns 0) 1.2.0horizontalAccuracy horizontal precision, unit m1.2.0

Sample code:

Wx.getLocation ({type: 'wgs84', success: function (res) {var latitude = res.latitude var longitude = res.longitude var speed = res.speed var accuracy = res.accuracy}}) wx.chooseLocation (OBJECT)
