MIME-type和Content-Type的关系：
当web服务器收到静态的资源文件请求时，依据请求文件的后缀名在服务器的MIME配置文件中找到对应的MIME Type，再根据MIME Type设置HTTP Response的Content-Type，然后浏览器根据Content-Type的值处理文件。types {Content-Type                          文件名后缀    text/html                             html htm shtml;text/css                              css;text/xml                              xml;image/gif                             gif;image/jpeg                            jpeg jpg;application/javascript                js;application/atom+xml                  atom;application/rss+xml                   rss;text/mathml                           mml;text/plain                            txt;text/vnd.sun.j2me.app-descriptor      jad;text/vnd.wap.wml                      wml;text/x-component                      htc;image/png                             png;image/tiff                            tif tiff;image/vnd.wap.wbmp                    wbmp;image/x-icon                          ico;image/x-jng                           jng;image/x-ms-bmp                        bmp;image/svg+xml                         svg svgz;image/webp                            webp;application/font-woff                 woff;application/java-archive              jar war ear;application/json                      json;application/mac-binhex40              hqx;application/msword                    doc;application/pdf                       pdf;application/postscript                ps eps ai;application/rtf                       rtf;application/vnd.apple.mpegurl         m3u8;application/vnd.ms-excel              xls;application/vnd.ms-fontobject         eot;application/vnd.ms-powerpoint         ppt;application/vnd.wap.wmlc              wmlc;application/vnd.google-earth.kml+xml  kml;application/vnd.google-earth.kmz      kmz;application/x-7z-compressed           7z;application/x-cocoa                   cco;application/x-java-archive-diff       jardiff;application/x-java-jnlp-file          jnlp;application/x-makeself                run;application/x-perl                    pl pm;application/x-pilot                   prc pdb;application/x-rar-compressed          rar;application/x-redhat-package-manager  rpm;application/x-sea                     sea;application/x-shockwave-flash         swf;application/x-stuffit                 sit;application/x-tcl                     tcl tk;application/x-x509-ca-cert            der pem crt;application/x-xpinstall               xpi;application/xhtml+xml                 xhtml;application/xspf+xml                  xspf;application/zip                       zip;application/octet-stream              bin exe dll;application/octet-stream              deb;application/octet-stream              dmg;application/octet-stream              iso img;application/octet-stream              msi msp msm;application/vnd.openxmlformats-officedocument.wordprocessingml.document    docx;application/vnd.openxmlformats-officedocument.spreadsheetml.sheet          xlsx;application/vnd.openxmlformats-officedocument.presentationml.presentation  pptx;audio/midi                            mid midi kar;audio/mpeg                            mp3;audio/ogg                             ogg;audio/x-m4a                           m4a;audio/x-realaudio                     ra;video/3gpp                            3gpp 3gp;video/mp2t                            ts;video/mp4                             mp4;video/mpeg                            mpeg mpg;video/quicktime                       mov;video/webm                            webm;video/x-flv                           flv;video/x-m4v                           m4v;video/x-mng                           mng;video/x-ms-asf                        asx asf;video/x-ms-wmv                        wmv;video/x-msvideo                       avi;
