【问题描述】：

我有一个内置 downloadHandler 的闪亮应用程序，它适用于较小的数据集，但当文件变大 (330 MB) 时，它会超时并出现错误。

我发现了这个 SO question (shiny downloadHandler timeout)，虽然我不知道如何更新配置文件以考虑到http_keepalive_timeout，但它似乎解决了答案。

下面是我的配置文件：

# Instruct Shiny Server to run applications as the user "shiny"
run_as shiny;


# Define a server that listens on port 3838
server 
  listen 3838;

  # Define a location at the base URL
  location / 

    # Host the directory of Shiny Apps stored in this directory
    site_dir /srv/shiny-server;

    # Log all Shiny output to files in this directory
    log_dir /var/log/shiny-server;

    # When a user visits the base URL rather than a particular application,
    # an index of the applications available in this directory will be shown.
    directory_index on;

  

【参考方案1】：

使用这个 SO 答案 User session is getting interrupted after approx. 45 seconds 修复它

我将http_keepalive_timeout 函数放在了错误的位置。请参阅下面的正确shiny-server.conf 更新：

# Instruct Shiny Server to run applications as the user "shiny"
run_as shiny;
http_keepalive_timeout 180;

# Define a server that listens on port 3838
server 
  listen 3838;

  # Define a location at the base URL
  location / 

    # Host the directory of Shiny Apps stored in this directory
    site_dir /srv/shiny-server;

    # Log all Shiny output to files in this directory
    log_dir /var/log/shiny-server;

    # When a user visits the base URL rather than a particular application,
    # an index of the applications available in this directory will be shown.
    directory_index on;

您好，同样的问题...您使用的是shiny-server pro还是开源版本？

使用开源版本。确保将函数放在配置文件的正确部分。
