我想将以下字符串转换为网址
www.mydomain.com/key=अक्षय
我尝试了let urlToSend = URL(string: "www.mydomain.com/key=अक्षय")!
,但它返回了nil。
我从textField获得了'षक्षय'关键字,它可以是任何本地语言。
它适用于英语但不能使用当地语言。
我使用let url = URL(string: "www.mydomain.com")?.appendingPathComponent("key=अक्षय")
它给出了www.mydomain.com/key=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
但现在我想
www.mydomain.com/key=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
至www.mydomain.com/key=अक्षय

将URL作为字符串使用时,您应该将它们编码为URL有效;对URL进行编码的最常见示例之一是“”(空格)将被编码为“%20”。
因此,在您的情况下,您的网址的编码值应为:
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css">
</head>
<div class="container">
<div class="col-md-3">
<form class="navbar-form" role="search" action="javascript:alert('Inner Function performed!');">
<div class="input-group add-on">
<input class="form-control" placeholder="Search" name="srch-term" id="srch-term" type="text">
<div class="input-group-btn">
<button class="btn btn-default" type="submit"><i class="glyphicon glyphicon-search"></i></button>
</div>
</div>
</form>
</div>
</div>
您注意到www.mydomain.com%2Fkey=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
的值已更改
来自:“अक्षय”
到: “%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF”
将使URL有效。
如何:
你可以得到上面这样的结果:
key
请注意,为了安全起见,编码字符串和网址都有可选绑定。
解码网址
您还可以返回原始未编码的网址(解码),如下所示:
let string = "www.mydomain.com/key=अक्षय"
if let encodedString = string.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed), let url = URL(string: encodedString) {
print(url) // www.mydomain.com%2Fkey=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
}
同样,可选的绑定是安全的。

您需要对网址进行编码。
let urlString = "www.mydomain.com/key=अक्षय".addingPercentEncoding(withAllowedCharacters: .urlPathAllowed)
let url = URL(string: urlString!)
let decodedUrl = urlString?.removingPercentEncoding
请记住,您不应强制解包网址和字符串,如果是let或guard语句则使用。

尝试这件事:
let strURL = "www.mydomain.com/key=अक्षय".addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)
let url = URL(string: strURL!)
或者您可以使用:
let strURL = "www.mydomain.com/key=अक्षय".addingPercentEncoding(withAllowedCharacters: .urlPathAllowed)
let url = URL(string: strURL!)
答案 3 :(得分:1)
您可以使用appendingPathComponent
逐个构建网址,而不是明确处理百分比编码:
let url = URL(string: "www.mydomain.com")?.appendingPathComponent("key=अक्षय")
// www.mydomain.com/key=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF

Swift3.0
let baseUrl = "www.mydomain.com/key=अक्षय" // base url
let encodedUrl : String! = baseUrl.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) // remove the spaces in the url string
let typeUrl = URL(string: encodedUrl)! // convert the string into url
print(typeUrl) // www.mydomain.com/key=%E0%A4%85%E0%A4%95%E0%A5%8D%E0%A4%B7%E0%A4%AF
用于检查目的
if let unwrappedDecodedString = encodedUrl.removingPercentEncoding {
print(decodedString) // www.mydomain.com/key=अक्षय
}
