更新阿拉莫火后，responseString从5.0更改为5.3

Question

我收到的json：

{
    "buyer": {
        "tmallMemberLevel": 0
    },
    "consumerProtection": {
        "items": [{
            "desc": "ÕýÆ·±£ÕÏ£¬¼ÙÒ»ÅâËÄ",
            "title": "¼ÙÒ»ÅâËÄ",
            "type": 0
        }, {
            "desc": "³ÏÐÅÓû§ÔÚÍË»õ¼Ä³öºó£¬ÏíÊܼ«ËÙÍË¿îµ½ÕË",
            "title": "¼«ËÙÍË¿î",
            "type": 0
        }, {
            "desc": "Âú×ãÏàÓ¦Ìõ¼þʱ£¬Ïû·ÑÕß¿ÉÉêÇë ¡°ÆßÌìÎÞÀíÓÉÍË»»»õ¡±",
            "title": "ÆßÌìÎÞÀíÓÉÍË»»",
            "type": 0
        }]
    }
}

使用Alamofire 5.0，responseString是：

{"buyer":{"tmallMemberLevel":0},"consumerProtection":{"items":[{"desc":"正品保障，假一赔四","title":"假一赔四","type":0},{"desc":"诚信用户在退货寄出后，享受极速退款到账","title":"极速退款","type":0},{"desc":"满足相应条件时，消费者可申请 “七天无理由退换货”","title":"七天无理由退换"

中文节目正确。

然而，在Alamofire 5.3中，responseString是：

{"buyer":{"tmallMemberLevel":0},"consumerProtection":{"items":[{"desc":"ÕýÆ·±£ÕÏ£¬¼ÙÒ»ÅâËÄ","title":"¼ÙÒ»ÅâËÄ","type":0},{"desc":"³ÏÐÅÓû§ÔÚÍË»õ¼Ä³öºó£¬ÏíÊܼ«ËÙÍË¿îµ½ÕË","title":"¼«ËÙÍË¿î","type":0},{"desc":"Âú×ãÏàÓ¦Ìõ¼þʱ£¬Ïû·ÑÕß¿ÉÉêÇë ¡°ÆßÌìÎÞÀíÓÉÍË»»»õ¡±"

中国人变成了乱糟糟的代码。

如何解决这个问题？

Answer 1

使用GBK编码来响应字符串：

extension String.Encoding {
    
    public static var GB_18030_2000: String.Encoding {
        let cfEncoding = CFStringEncodings.GB_18030_2000
        let resEncoding = CFStringConvertEncodingToNSStringEncoding(CFStringEncoding(cfEncoding.rawValue))
        return String.Encoding(rawValue: resEncoding)
    }
    
}
