Question

我正在使用GET方法，我必须在URL中传递电子邮件地址。 API期望它被编码。我试过编码选项，但'+'字符无法编码。

我尝试使用以下代码

let encodedEmail = emailAddressTxt.text!.addingPercentEncoding(withAllowedCharacters:.urlHostAllowed)

let urlString = "http://www.example.com/User/GetUserDetailsByEmailAddress?EmailAddress=\(encodedEmail!)"

print(escapedString)

打印http://www.example.com/User/GetUserDetailsByEmailAddress?EmailAddress=mano+1%40gmail.com

“@”字符仅编码且“+”未编码。

Answer 1

不幸的是，CharacterSet.urlHostAllowed和CharacterSet.urlQueryAllowed都包含+ 允许。由于历史原因，大多数Web服务器会将+视为空格的替换（），因此您需要转义+。

出于此目的，您可能需要定义自己的CharacterSet：

extension CharacterSet {
    static let rfc3986Unreserved = CharacterSet(charactersIn: "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-._~")
}

let emailAddressText = "mano+1@gmail.com"

let encodedEmail = emailAddressText.addingPercentEncoding(withAllowedCharacters:.rfc3986Unreserved)

print(encodedEmail!) //->mano%2B1%40gmail.com

Answer 2

使用.urlHostAllowed字符集＆＃39; +＆＃39;没有编码。

将扩展名添加到String，如下所示

public func stringByAddingPercentEncodingToData() -> String? {
    let finalString = self.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)?.replacingOccurrences(of: "&", with: "%26").replacingOccurrences(of: "+", with: "%2B")
    return finalString
}

你可以这样做。

Answer 3

试试这个：

let encodedEmail = emailAddressTxt.text!

        var urlString = "http://yyy.xxx.com/User/GetUserDetailsByEmailAddress?EmailAddress=\(encodedEmail)"
        urlString = urlString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)

或

let encodedEmail = emailAddressTxt.text！

let urlString = "http://yyy.xxx.com/User/GetUserDetailsByEmailAddress?EmailAddress=\(encodedEmail!)"
urlString = urlString.addingPercentEncoding(withAllowedCharacters:.urlHostAllowed)

print(escapedString)

无法在URL + swift中编码Plus字符
