我只想将 id + 一些值添加到 DynamoDb 一次。如果 id 已经存在，它应该什么都不做或更新

我可以去

search 

if not found > insert

if found > do nothing or update (for now do nothing is fine)

但希望有更好的方法来做到这一点。id 应该是要检查的关键。

这是节点中的代码：

const dynamodbParams = {
        TableName: process.env.DYNAMODB_TABLE_BLICKANALYTICS,
        Item: {
          id: userId,
          createdAt: timestamp
        },
      };

      dynamoDb.put(dynamodbParams).promise()
      .then(data => {
        console.log('saved: ', dynamodbParams);
      })
      .catch(err => {
        console.error(err);
      });  

我在 yml 中使用它。不知道yml有没有设置这个选项

resources:
  Resources:
    DynamoDbTableExpenses:
      Type: 'AWS::DynamoDB::Table'
      DeletionPolicy: Retain
      Properties:
        AttributeDefinitions:
          -
            AttributeName: id
            AttributeType: S
          -  
            AttributeName: createdAt
            AttributeType: N …

是否有一个选项可以同时取消一个存储库中所有计划的 github 操作的运行。总是去这里取消运行需要很多点击。

我尝试在烧瓶模板中输出pandas数据帧.我的想法是将它转换为json然后遍历表格

我测试了这个

jsonfiles = df.to_json(orient='records')

return render_template('index.html', ctrsuccess=jsonfiles)

在模板中,我尝试输出如下:

        {%if ctrsuccess %}
        <div class="table-responsive">
            <table class="table table-striped">
                <tbody>
                    {%for ctrrow in ctrsuccess %}
                    <tr>
                        <td>{{ ctrrow['positionint'] }}</td>
                    </tr>
                    {%endfor%}
                </tbody>
            </table>
        </div>
        {%endif%}

在模板中,如果我只是绘制ctrsuccess,我会得到一个正确的json.但桌子是空的

我尝试在 firebase 函数中运行 puppeteer。据我了解 https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md#running-puppeteer-on-google-cloud-functions 它应该可以添加

 "engines": {
    "node": "8"
  },

在 package.json 中。我得到了它使用 firebase deploy 的积极反馈

 functions: updating Node.js 8 function helloWorld(us-central1)...

可悲的是它兑现了

在本地测试了相同的代码。

那是失败的云函数代码。

const functions = require('firebase-functions');

const puppeteer = require('puppeteer');
let browser = ""
let page = ""

const startPuppeteer = async () => {
    browser = await puppeteer.launch(); …
