C# 如何使用维基百科API在坐标中包含距离?
在我的维基百科API中,我得到了一个地方的坐标。这个坐标包含lat、lon、dim、type等,但我还想在坐标中添加dist,这样我就可以从一个API获得每个位置的距离。我当前的API是-C# 如何使用维基百科API在坐标中包含距离?,c#,json,api,wikipedia-api,mediawiki-api,C#,Json,Api,Wikipedia Api,Mediawiki Api,在我的维基百科API中,我得到了一个地方的坐标。这个坐标包含lat、lon、dim、type等,但我还想在坐标中添加dist,这样我就可以从一个API获得每个位置的距离。我当前的API是- https://en.wikipedia.org/w/api.php?format=json&action=query&redirects=1&generator=geosearch&prop=extracts|coordinates|pageimages&ggslim

在搜索位置的查询时,我发现了以下API:

现在我想知道有没有办法在我以前的API中包含“dist”?是的,您可以通过使用codistancefrompoint参数在API中包含
dist
,该参数是主API请求中已经使用的参数的一部分,因此您不需要使用其他API。此参数的值必须是您的入口点,因此它必须与ggscoord
相同:
codistancefrompoint=52.5243700|13.4105300
在这种情况下,对于每个结果,将测量从该入口点到结果点的距离
以下是您的新API查询:
https://en.wikipedia.org/w/api.php?format=json&action=query&redirects=1&generator=geosearch&prop=extracts|coordinates|pageimages&ggslimit=20&ggsradius=1000&ggscoord=52.5243700|13.4105300&formatversion=2&exintro=1&explaintext=1&exlimit=20&coprop=type|dim|globe&colimit=20&piprop=thumbnail&pithumbsize=400&pilimit=20&codistancefrompoint=52.5243700|13.4105300
结果如下:
"query":{
"pages":[
{
"pageid":2511,
"ns":0,
"title":"Alexanderplatz",
"extract":"Alexanderplatz (pronounced [ʔalɛkˈsandɐˌplats]) is a large public square and transport hub in the central Mitte district of Berlin, near the Fernsehturm.

"coordinates":[
{
"lat":52.52166748,

"type":"landmark",

非常感谢你的回答。
