WKWebView加载带#的url,无法访问

今天在做项目中，遇到用WKWebView加载url,无法访问。最后发现是url里面的#被编码成%23导致无法访问

https://127.0.0.1/#/?name=华为

编码之后：

https://127.0.0.1/%23/?name=%E5%8D%8E%E4%B8%BA

当 # 号被编译成 %23 之后无法访问

解决办法：禁止 **# ** 号编译成 **%23 **

OC

- (NSString *)WM_FUNC_urlEncode:(NSString *)urlStr{
    NSMutableCharacterSet *set  = [[NSCharacterSet URLQueryAllowedCharacterSet] mutableCopy];
    [set addCharactersInString:@"#"];
    return [urlStr stringByAddingPercentEncodingWithAllowedCharacters:set];
}

swift 4.0

func WM_FUNC_urlEncode(_ urlStr:String) -> String {
    if urlStr.isEmpty {
        return ""
    }
    var charSet = CharacterSet.urlQueryAllowed
    charSet.insert(charactersIn: "#")
    let encodingURLStr = urlStr.addingPercentEncoding(withAllowedCharacters: charSet)
    return encodingURLStr ?? ""
}

下面模仿oc写法： CharacterSet转换NSMutableCharacterSet来操作

func WM_FUNC_urlEncode(_ urlStr:String) -> String {
    if urlStr.isEmpty {
        return ""
    }
    let charSet = CharacterSet.urlQueryAllowed as NSCharacterSet
    let mutSet = charSet.mutableCopy() as! NSMutableCharacterSet
    mutSet.addCharacters(in: "#")
    let encodingURLStr = urlStr.addingPercentEncoding(withAllowedCharacters: mutSet as CharacterSet)
    return encodingURLStr ?? ""
}

func WM_FUNC_urlEncode(_ urlStr:String) -> String {
    if urlStr.isEmpty {
        return ""
    }
    let charSet = NSMutableCharacterSet()
    charSet.formUnion(with: CharacterSet.urlQueryAllowed)
    charSet.addCharacters(in: "#")
    let encodingURLStr = urlStr.addingPercentEncoding(withAllowedCharacters: charSet as CharacterSet)
    return encodingURLStr ?? ""
}
