我想使用get参数发送url:
let customAllowedSet = NSCharacterSet(charactersInString:"=\"#%/<>?@\\^`{|}&").invertedSet
guard let safeUrl = "\(GVariables.Url)?id=\(self.UUID)&device_name=\(UIDevice.currentDevice().name)&email=\(email)&first_name=\(firstName)&last_name=\(lastName)".stringByAddingPercentEncodingWithAllowedCharacters(customAllowedSet) else {
return
}
print(safeUrl)
guard let url = NSURL(string: safeUrl) else {
return
}
print(url)
输出是:
的http:%2F%2Fmyurl.com:8000%2FS%2F%3Fid%3D15FDA6B3-C51A-4057-8F98-0143981CC5C8%26device_name%3DArtem的 iPhone%26email%3D%26first_name%3D%26last_name%3D
但转换为NSURL始终返回nil
。

您用来对网址进行编码的自定义字符集看起来效率很高,但不完整。
在你的情况下,例如,它缺少对空格字符的编码&#34; &#34;
最好使用已知方法:
yourStringURL.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLFragmentAllowedCharacterSet())
