更新 Shiny 服务器配置以更改超时错误

Question

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

我发现这个 SO 问题（闪亮的 downloadHandler timeout）似乎解决了答案，尽管我不知道如何更新配置文件以考虑http_keepalive_timeout。

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;

  }
}

我把这个http_keepalive_timeout函数放在了错误的地方。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;

  }
}
