nginx/tengin aktiviert gzip nicht für PHP-Dateien, aber warum enthält der Rückgabeheader Content-Encoding: gzip?

Question

Die

nginx gzip-Konfiguration lautet wie folgt:

gzip on;
gzip_min_length  1k;
gzip_buffers     4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types       text/plain application/x-javascript application/javascript text/css application/xml;
gzip_vary on;

Mit Curl oder Chrome testen

$curl -I -H "Accept-Encoding: gzip, deflate" "http://localhost/template/tpl_header.php"

HTTP/1.1 200 OK
Server: Tengine/2.1.0
Date: Sat, 05 Sep 2015 16:40:34 GMT
Content-Type: text/html
Connection: keep-alive
Vary: Accept-Encoding
X-Powered-By: PHP/5.5.27
Content-Encoding: gzip

Das Anfordern von JPG-Bildern ist normal

curl -I -H "Accept-Encoding: gzip, deflate" "http://localhost/asset/image/common/bg.jpg"

HTTP/1.1 200 OK
Server: Tengine/2.1.0
Date: Sat, 05 Sep 2015 16:43:36 GMT
Content-Type: image/jpeg
Content-Length: 4817

Cache-Control: max-age=2592000
Accept-Ranges: bytes

Was ist der Grund dafür?

Anbei sind die Kompilierungsparameter:

./configure --prefix=/usr/local/nginx --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --conf-path=/etc/nginx/nginx.conf --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --pid-path=/var/run/nginx.pid --with-cc-opt="-Wno-deprecated-declarations"

因为你的php的header输出为text/html
