配置：Rack :: Cache没有出现在中间件中

问题描述

我按照Heroku的教程使用Memcache。我的目标是缓存我的资产（js / css /图像）：https://devcenter.heroku.com/articles/rack-cache-memcached-rails31

我按照说明进行了配置： config / application.rb

import requests
import gspread
import urllib.parse
import pickle



spreadsheetId = "###"  # Please set the Spreadsheet ID.
cellRange = "Yoursheetname!A1:A100"  # Please set the range with A1Notation. In this case,the hyperlink of the cell "A1" of "Sheet1" is retrieved.


with open('token_sheets_v4.pickle','rb') as token:
    # get this file here
    # https://developers.google.com/identity/sign-in/web/sign-in
    credentials = pickle.load(token)

client = gspread.authorize(credentials)

# 1. Retrieve the access token.
access_token = client.auth.token

# 2. Request to the method of spreadsheets.get in Sheets API using `requests` module.
fields = "sheets(data(rowData(values(hyperlink))))"
url = "https://sheets.googleapis.com/v4/spreadsheets/" + spreadsheetId + "?ranges=" + urllib.parse.quote(cellRange) + "&fields=" + urllib.parse.quote(fields)
res = requests.get(url,headers={"Authorization": "Bearer " + access_token})
print(res)

# 3. Retrieve the hyperlink.
obj = res.json()
print(obj)
link = obj["sheets"][0]['data'][0]['rowData'][0]['values'][0]['hyperlink']
print(link)

config / production.rb

config.cache_store = :mem_cache_store

我也有一个疑问，因为我在运行“ Rake中间件”时没有看到Rack缓存（我有这个

# Code is not reloaded between requests.
  config.cache_classes = true

  # Full error reports are disabled and caching is turned on.
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Compress JavaScripts and CSS.
  config.assets.compress = true

  # Do not fallback to assets pipeline if a precompiled asset is missed.
  config.assets.compile = false

  # Use a different cache store in production.
  config.cache_store = :mem_cache_store

  # Cache static assets
  config.serve_static_assets = true

  # Generate digests for assets URLs
  config.assets.digest = true

  client = Dalli::Client.new((ENV["MEMCACHIER_SERVERS"] || "").split(","),:username => ENV["MEMCACHIER_USERNAME"],:password => ENV["MEMCACHIER_PASSWORD"],:failover => true,:socket_timeout => 1.5,:socket_failure_delay => 0.2,:value_max_bytes => 10485760)
  config.action_dispatch.rack_cache = {
    :metastore    => client,:entitystore  => client
  }
  config.public_file_server.headers = { 'Cache-Control' => 'public,max-age=2592000' }

  config.action_mailer.perform_caching = false

我也在生产中检查了日志，似乎memcacher正在运行，他只是显示“ miss”而不是存储或新鲜。我遵循heroku给出的“调试部分”，然后尝试使用：p来检查y资产之一。

没有：

X-Rack-Cache：新鲜

似乎在od Rack :: cache的配置中有问题...

您能从哪里找到问题的一个主意吗？感谢帮助
