异常：参数太大：值 Google 脚本

Question

我正在尝试抓取一个网站并将值放入缓存中，这样我就不会达到 UrlFetchApp 的每日限制

这是我做的脚本：

/**
 * Scrape URL, return whatever you choose with jquery-style selectors. 
 Dependency: cheeriogs, see https://github.com/fgborges/cheeriogs
 *
 * @param {url} valid start-url
 * @return result (array values)
 *
 * @customfunction
 */
function scrapercache(url) {
    var result = [];
    var description;
    var options = {
        'muteHttpExceptions': true,
        'followRedirects': false,
    };
  
var cache = CacheService.getScriptCache();
var properties = PropertiesService.getScriptProperties();

try {  
  let res = cache.get(url);

  if (!res) {
    // trim url to prevent (rare) errors
    url.toString().trim();
    var r = UrlFetchApp.fetch(url, options);
    var c = r.getResponseCode();

    // check for meta refresh if 200 ok
    if (c == 200) {
      var html = r.getContentText();
      cache.put(url, "cached", 21600);
      properties.setProperty(url, html);

      var $ = Cheerio.load(html); // make sure this lib is added to your project!

      // meta description
      if ($('meta[name=description]').attr("content")) {
        description = $('meta[name=description]').attr("content").trim();
      }
    }
  
    result.push([description]);    
  }
} 
catch (error) {
  result.push(error.toString());
} 
finally {
  return result;
}
 
}

但是当我这样调用函数时：

=scrapercache("https://www.gurufocus.com/term/total_freecashflow/nyse:ABBV/Free-Cash-Flow")

我收到错误消息：

Exception: argument too large: value

有人可以帮助我吗？谢谢：）加布里埃尔

Answer 1

如 official documentation、

中所写

The maximum length of a key is 250 characters. The maximum amount of data that can be stored per key is 100KB.

如果放入缓存的数据大小超过上述任何限制，错误

Exception: argument too large

显示。在您的情况下，value 超过 100KB。解决方案是根据您的具体需要只缓存必要的数据或根本不缓存。
