在IE浏览器下载.apk后缀文件自动变为.zip的问题

在Nginx安装目录下的conf/mime.types文件的对应位置，加上以下一行语句，指定APK文件的MIME类型为：

application/vnd.android.package-archive     apk;

其他类型添加

text/vnd.sun.j2me.app-descriptor      jad;
application/java-archive              jar war ear;
application/x-java-archive-diff       jardiff;
application/vnd.android.package-archive apk;
application/vnd.ms-cab-compressed              cab;
application/octet-stream              bin exe dll;
application/vnd.symbian.install       sis;
x-epoc/x-sisx-app                     sisx;
application/iphone                    pxl ipa;
application/vnd.palm                  prc pdb;
application/vnd.webos.ipk             ipk;
application/vnd.rim.cod               cod;
application/mrp                       mrp;
x-nokia-widget                        wgz;
application/octet-stream              deb;
