Question

因此，我们开始在项目中使用摘要机制。在vc中，我有以下方法：

  func imageThumbnailcall() {

    self.indicaotrTimer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(self.HandleOverTime), userInfo: nil, repeats: false)
    self.backgroundImageTimer = Timer.scheduledTimer(withTimeInterval: 0.09, repeats: true, block: { (timer) in

        SDWebImageDownloader.shared().setValue("\(UserDefaults.standard.string(forKey: "imageHeader") ?? "YWRtaW46YWRtaW4=")", forHTTPHeaderField: "Authorization")

        SDWebImageDownloader.shared().downloadImage(with:(self.isShowingThermal ? self.thermalUrl : self.visualUrl) as URL, options: [], progress: nil, completed: { (image, data, error, status) in
            self.imageLoaderIndicator.stopAnimating()
            self.backGroundImageView.image = image
        })
    })

}

在上述调用中，我需要用摘要1替换标题，因此我进行了alamofire调用，出现401错误，并将其作为标题：

 - some : <NSHTTPURLResponse: 0x1d42265a0> { URL: http://192.168.42.1/images/snapshots/DLTVimage.jpeg } { Status Code: 401, Headers {
Connection =     (
    "keep-alive"
);
"Content-Length" =     (
    195
);
"Content-Type" =     (
    "text/html"
);
Date =     (
    "Tue, 02 Oct 2018 13:22:25 GMT"
);
"Www-Authenticate" =     (
    "Digest algorithm=\"MD5\", qop=\"auth\", realm=\"Restricted access\", nonce=\"18f42caa5bb37111\""
);
 } }

我了解的是，我需要创建一个像这样的字符串：

Digest username="admin",realm="Restricted access",nonce="1d382e075bac95ba",uri="/images/snapshots//IRimage.jpeg",response="54c5aad4e9854201c5e66375f41769d2",cnonce="db860bdba0f3f328",algorithm=MD5,qop=auth,nc=00000001"

并将其用作标题。我可以做到这一点吗，并且有一个豆荚可以帮上忙吗？

所以我做的是以下方法：

func imageStreamTest(url: String, success: @escaping (UIImage) -> Void, failure: @escaping () -> Void) {
    Alamofire.request(url).authenticate(user: UserDefaults.standard.string(forKey: "userName") ?? "", password: UserDefaults.standard.string(forKey: "password") ?? "").responseData { (responseObject) -> Void in

        if responseObject.error != nil {
            return
        }

        if let image1 = responseObject.result.value {
            guard let image = UIImage(data: image1) else { return }
            success(image)
        }
    }
}

Alamofire正在处理摘要身份验证，我得到的数据是200。在后台发生401故障并由alamofire处理
