下載模塊:
cd /tmpwget https://codeload.github.com/vkholodkov/nginx-upload-module/zip/2.2unzip 2.2
安裝模塊:
.configure --add-module=/tmp/nginx-upload-module-2.2/multipart/form-data表單上傳示例
nginx.conf配置:
server { [...] location /upload { upload_pass @uploadHandler; upload_store /usr/local/nginx/upload_temp 1; upload_set_form_field $upload_field_name.path "$upload_tmp_path"; } location @uploadHandler { proxy_pass http://backend-host; } [...] }
這裡在server裡定義了upload location,這個location是上傳的接口,還有@uploadHandler location,是當文件上傳完成後,nginx模塊會對這個location發送一些必要的信息,如文件上傳的路徑,這裡涉及了幾個指令:
斷點續傳示例upload_pass @uploadHandler:上傳完成後會發送必要的數據到@uploadHandler;
upload_store /usr/local/nginx/upload_temp 1: 文件上傳的臨時目錄;
upload_set_form_field $upload_field_name.path “$upload_tmp_path”: 設置文件上傳完成後,把文件臨時路徑發送給upload_pass指定的location。
nginx.conf配置
server {[...] location /resumable_upload { upload_resumable on; upload_state_store /usr/local/nginx/upload_temp ; upload_pass @drivers_upload_handler; upload_store /usr/local/nginx/upload_temp; upload_set_form_field $upload_field_name.path "$upload_tmp_path"; } location @resumable_upload_handler { proxy_pass http://localhost:8002; } [...] }
上傳文件第一個片段與上一步multipart/form-data表單上傳示例配置不同的地方有:
upload_resumable on: 開啟斷點續傳功能;
upload_state_store /usr/local/nginx/upload_temp: 設置斷點續傳狀態文件存儲的目錄。
