Ios 不能'；t在URL+中编码加号字符；敏捷的

我使用的是GET方法，我必须在URL中传递电子邮件地址。API希望对其进行编码。我尝试使用编码选项，但无法对“+”字符进行编码

我尝试了以下代码

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

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

print(escapedString)

它打印

其中“@”字符仅编码而“+”未编码。

请尝试以下操作：

let encodedEmail = emailAddressTxt.text!

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

或

让encodedEmail=emailAddressTxt.text

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

print(escapedString)

使用.urlHost时，不编码允许的字符集“+”

向字符串添加扩展名，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
}

您可以这样做。

不幸的是，

字符集.urlHostAllowed

和

字符集.urlQueryAllowed

都包含

+

作为允许的。由于历史原因，大多数web服务器将

+

视为空白（

）的替代品，因此您需要转义

+

为此，您可能需要定义自己的

字符集

：

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

您应该为URL的该部分使用urlQueryAllowed，但加号不需要转义。
