使用 gmail 和应用程序脚本解析 google 条提醒

Question

我设置了 google 警报并收到如下所示的警报电子邮件：

我想解析警报并将其保存在 google sheet 中，格式为：alert_name,publication_date, title,news source

不知道从哪里开始 help/guidance 感谢谢谢

Answer 1

您可以将 gmail api 与 appscript 一起使用，GmailApp 的工作方式与 gmail api 的工作方式非常相似。

您应该做的第一件事是在 gmail 网络应用程序中创建一个搜索，该搜索将 return 只是您要查找的邮件

var threads = GmailApp.search('from:(googlealerts-noreply@google.com)');
for(var i=0; i<threads.length; i++)
 {
   messages = threads[i].getMessages();
   for(var j=0; j<messages.length; j++)
      {
        var date = messages[j].getDate();
        var body = messages[j].getPlainBody();
        var start = body.indexOf('<table');
        var end = body.indexOf('</table>');          
                       
          }             

          }             
      }
   }   
  }

正文以 html 格式返回，因此您必须对其进行清理才能找到所需的文本。找到所需的文本后，您可以使用 SpreadsheetApp

将其写入 sheet

function WriteToSheet(date, value){
  var sheet = SpreadsheetApp.getActiveSheet();
  sheet.appendRow([date, value]);


}

此代码来自我用来扫描我自己的一封电子邮件中的一些文本的脚本。

尽管我同意 @Ruben has given in the comments, I think this topic is interesting and could help other users to save and manage their Google Alerts 的观点。

`Code.gs`

/* Retrieve all news from googlealert source */
const threads = GmailApp.search('from:(googlealerts-noreply@google.com)')
/* Our sheet for save the news */
const sS = SpreadsheetApp.openById(SS_ID).getSheetByName('Google Alerts')
/* Control the already added answers */
let addedNews = []
try { addedNews = sS.getRange('A1:A' + sS.getLastRow()).getValues().flat() } catch (err) { }

function parseContent() {
  const totalNews = []
  /* Maybe add a control system for remove the threads already saved */
  threads.forEach((th) => {
    const msgs = th.getMessages()
    msgs.forEach((msg) => {
      /* Divide the content in new lines an parse the content */
      const body = msg.getPlainBody().split('\n')
      /* Extract the filter name eg === News - 2 new results for [python] === */
      const filterName = body.slice(0, 1)[0].match(/\[(.*?)\]/)[1]
      const date = msg.getDate()
      /* Remove the unnecessary lines  */
      const cleanedBody = body.slice(1, -11)
      /* Detect the news via empty new lines "\r" */
      const newsIdxs = cleanedBody.reduce((pre, curr, idx) => {
        curr === "\r" && pre.push(idx)
        return pre
      }, [])
      newsIdxs.forEach((v, idx, arr) => {
        if (idx == arr.length - 1) return
        /* From one empty line to the nex */
        const parsedNew = cleanedBody.slice(v + 1, arr[idx + 1])
        /* Simply extracted from the first line */
        const title = parsedNew[0].split('|')[0]
        /* Last line and between <> */
        const url = parsedNew[parsedNew.length - 1].match(/<(.*?)>/)[1]
        /* Extracted from the URL rather than the title due variability  */
        const source = url.match(/url=https:\/\/(.*?)\//)[1]
        totalNews.push({ title, url, date, source, filterName })
      })
    })
  })
  totalNews.forEach((nw) => {
    /* Hash the object for preventing adding already present  */
    const id = hashCode(Object.values(nw).toString())
    if (addedNews.includes(id)) return
    sS.appendRow([id, ...Object.values(nw)])
  })
}

/* Extracted from here  */
const hashCode = s => s.split('').reduce((a, b) => { a = ((a << 5) - a) + b.charCodeAt(0); return a & a }, 0)

`Results`

注意 1：此脚本是问题的近似值，仅针对与新闻相关的警报进行测试。

注2：感谢的pseudo-code，帮助我更快地解决问题。

注释 3：hashCode 函数已从 here

中提取

注释 4：我决定采用 RegExp due to the use of getPlainBody(), but I think that in this case, using a library that allows parsing HTML with getBody() 的方法更容易实现。
