The formula should be: longitude and latitude in any decimal number. The integer is the degree, and the fractional part is the score in the integer part of the number obtained by multiplying the decimal part by 60, multiply the decimal part of the number by 60 to get the number of seconds. For example, the number of degrees converted from 36.12432314 to second is: the number of degrees is "36", and the valu

Now my retreat is coming to an end. According to the initial plan, I plan to spend about a month studying JavascriptCodeObfuscation. Later, as the engine of Google App Engine is being studied more and more deeply, and code obfuscation is more complicated than I thought, I canceled the plan to study code obfuscation, focus on website-related research. This article introduces three Rest interface services that I implemented on Google App Engine: 1. query the service of administrative divisions
