wget下载文件---no-check-certificate错误？

Question

我有一个cron，每24小时将一个csv数据下载到我的服务器上。因为托管此csv的提供程序仅允许浏览器下载csv文件，所以我伪造了我的身份。但是问题是我仍然遇到错误。

有谁知道我该如何解决这个问题？

我的wget查询：

wget --no-check-certificate -O "/httpdocs/cronjob/data/gamesdeal.csv" "http://www.gamesdeal.com/media/feedgenerator/Gamekey.csv" --header="User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:23.0) Gecko/20100101 Firefox/23.0" --header="Accept: image/png,image/*;q=0.8,*/*;q=0.5" --header="Accept-Language: en-US,en;q=0.5" --header="Accept-Encoding: gzip, deflate" --header="Referer: http://www.gamesdeal.com"

我返回的错误：

问候和谢谢！

除了警告没有其他错误。--no-check-certificate品牌wget继续，尽管验证失败，但它仍然会抱怨-如果没有这个选项设置wget只会停留一次验证失败。

如果您有意使用该选项，则无需担心。如果要摆脱它，您只需要使用来自广为人知的CA的证书，或者使用诸如--ca-directory或--ca-certificate使其成为wget证书颁发者的选项。

可信证书基本上是指由应用程序已知的CA颁发的证书-存在已知和可信CA的数据库，如果您的证书匹配，那就很好。如果不是，则显示警告。要摆脱这种情况，您需要告诉应用程序您也希望它信任您的CA，这就是通过使用前面提到的选项可以实现的。
