swift - 当字符串充满特殊字符时，如何在swift中提取双引号内的特定单词？

Question

从给定的数据即 -

session_id="8b55ed3af15dcf154aaaedd1bb667489"/ip_address="103.16.104.24"/last_activity="1460548532"

我如何提取 session_id、ip_address 和 last_activity 的值。我试过下面的代码，但它只适用于简单的字符串，当我分配给定的数据时，它显示错误

var testString: String = "session_id="8b55ed3af15dcf154aaaedd1bb667489"/ip_address="103.16.104.24"/last_activity="1460548532""

var data: String = testString
let extractedStringData = data.componentsSeparatedByString("/")

var session_id: String = extractedStringData[0]
var ip_address: String? = extractedStringData[1]
var last_activity: String? = extractedStringData [2]

任何建议都会有帮助
谢谢

可能有更实用的方法来做到这一点，但这个有效:

var testString: String = "session_id=\"8b55ed3af15dcf154aaaedd1bb667489\"/ip_address=\"103.16.104.24\"/last_activity=\"1460548532\""

let pairs: [String] = testString.characters.split("/").map(String.init)
var values = [String:String]()
pairs.forEach({
    let pair: [String] = $0.characters.split("=").map(String.init)
    values[pair[0]] = pair[1]
})

testString: String = "session_id=\"8b55ed3af15dcf154aaaedd1bb667489\"/ip_address=\"103.16.104.24\"/last_activity=\"1460548532\""
pairs: [String] = 3 values {
  [0] = "session_id=\"8b55ed3af15dcf154aaaedd1bb667489\""
  [1] = "ip_address=\"103.16.104.24\""
  [2] = "last_activity=\"1460548532\""
}
values: [String : String] = 3 key/value pairs {
  [0] = {
    key = "last_activity"
    value = "\"1460548532\""
  }
  [1] = {
    key = "session_id"
    value = "\"8b55ed3af15dcf154aaaedd1bb667489\""
  }
  [2] = {
    key = "ip_address"
    value = "\"103.16.104.24\""
  }
}
