如何在Swift中编码URL [英] How to encode a URL in Swift

问题描述

这是我的网址。

问题是，地址字段未附加到 urlpath 。

The problem is, that the address field is not being appended to urlpath.

有谁知道为什么会这样？

Does anyone know why that is?

var address:string
address = "American Tourister, Abids Road, Bogulkunta, Hyderabad, Andhra Pradesh, India"
let urlpath = NSString(format: "http://maps.googleapis.com/maps/api/geocode/json?address="+"\(address)")

推荐答案

使用 stringByAddingPercentEncodingWithAllowedCharacters ：

var escapedAddress = address.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())

---

使用 stringByAddingPercentEscapesUsingEncoding： 在iOS 9和OS X v10.11中不推荐使用

var address = "American Tourister, Abids Road, Bogulkunta, Hyderabad, Andhra Pradesh, India"
var escapedAddress = address.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)
let urlpath = NSString(format: "http://maps.googleapis.com/maps/api/geocode/json?address=\(escapedAddress)")

SWIFT 3

var address = "American Tourister, Abids Road, Bogulkunta, Hyderabad, Andhra Pradesh, India"
let escapedAddress = address.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)
let urlpath = String(format: "http://maps.googleapis.com/maps/api/geocode/json?address=\(escapedAddress)")
