对于下面的[key:value]对，不太好用
A_Geo:“MULTIPOINT((121.5831587 24.9971109))”
我需要支持将其转换为字典并像其他对一样组合成字典数组
[ _id:1,.....,经纬度:121.5831587,纬度:24.9971109,......]
为了解析以下 JSON 以将地理数据分析为 lng 和 lat，我们尝试应用 JSONSerialization。但不知道更进一步。
result:
{
offset: 0,
limit: 10000,
results:[
-{
_id: "1",
A_Name_Ch: “Great Hotel Spot",
A_Geo: "MULTIPOINT ((121.5831587 24.9971109))",
A_Location: “Great Spot",
A_Name_En: "Giant Great",
A_CID: "1"
}, {…}, {…}
}
]
}
let ArticlesUrl = URL (string: "http://data.taipei/opendata/datalist/apiAccess?scope=resourceAquire&rid=a3e2b221-75e0-45c1-8f97-75acbd43d613")!
let session = URLSession.shared
let task = session.dataTask(with: ArticlesUrl){(data,response,error) in
if let error = error {
print ("failed!!")
completionHandler(nil,error)
return
}
let data = data!
if let jsonObject = try? JSONSerialization.jsonObject(with: data, options: .mutableContainers) as![String:[String: Any]], let articleArray = jsonObject["result"]!["results"] as? [[String: Any]]{
var articles = [Article]()
for articleDict in articleArray{
let article = Article(rawData: articleDict)
articles.append(article)
}
completionHandler(articles, nil)
}
}
task.resume()
最佳答案
解析 MULTIPOINT 字符串表达式的替代方法是 Scanner
let string = "MULTIPOINT ((121.5831587 24.9971109))"
let scanner = Scanner(string: string)
var lat = 0.0, lng = 0.0
if scanner.scanUpToCharacters(from: CharacterSet.decimalDigits, into: nil) {
scanner.scanDouble(&lat)
scanner.scanDouble(&lng)
}
let coordinate = ["lat" : lat, "lng" : lng]
关于JSON数据: A_Geo: "MULTIPOINT ((121.5831587 24.9971109))" need to be parsed into dictionary，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50637161/
