Question

我正在用 Arduino 做一个项目，我试图将变量的数据发布到谷歌表集成中，但代码不起作用。

我试图更正它，但无论如何它都没有发布......这是代码。

错误是

<块引用>

ss.sheet.getSheetByName 这不是函数

我从 Arduino IoT Cloud Google sheet Integration 中获取了代码

function myFunction() {
        // get sheet named RawData
        var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Dati");

        var MAX_ROWS = 1440;     // max number of data rows to display
        // 3600s / cloud_int(30s) * num_ore(12h)
        var HEADER_ROW = 1;     // row index of header
        var TIMESTAMP_COL = 1;  // column index of the timestamp column

        function doPost(e) {  
          var cloudData = JSON.parse(e.postData.contents); // this is a json object containing all info coming from IoT Cloud
          //var webhook_id = cloudData.webhook_id; // really not using these three
          //var device_id = cloudData.device_id;
          //var thing_id = cloudData.thing_id;
          var values = cloudData.values; // this is an array of json objects
          
          // store names and values from the values array
          // just for simplicity
          var incLength = values.length;
          var incNames = [];
          var incValues = [];
          for (var i = 0; i < incLength; i++) {
            incNames[i] = values[i].name;
            incValues[i] = values[i].value;
          }
          
          // read timestamp of incoming message
          var timestamp = values[0].updated_at;          // format: yyyy-MM-ddTHH:mm:ss.mmmZ
          var date = new Date(Date.parse(timestamp)); 
          
          /*
          This if statement is due to the fact that duplicate messages arrive from the cloud!
          If that occurs, the timestamp is not read correctly and date variable gets compromised.
          Hence, execute the rest of the script if the year of the date is well defined and it is greater
          then 2018 (or any other year before)
          */
          if (date.getYear() > 2018) {

            if (sheet.getRange(HEADER_ROW+1, 1).getValue() != '') { // for the first time app is run
              var now = new Date(); // now
              var COMM_TIME = 5; // rough overestimate of communication time between cloud and app
              if (now.getTime() - date.getTime() > COMM_TIME * 1000) {

您正尝试将数据直接推送到云端的 Google 表格，但出于安全原因，其 URL 使用 https。 https 的加密相当复杂，需要 SSL 加密。 Arduino 硬件通常不够快，无法执行 SSL。您需要更强大的硬件（例如 Raspberry Pi）才能直接写入 Google Cloud。

但是，如果您坚持在您的 IOT 项目中使用 Arduino（任何变体），您可以使用 PushingBox，一个可以根据 API 调用发送通知的云，为您完成繁重的工作。在这里，您将数据发送到 Pushingbox，它使用 http URL，然后将数据转至 Google 表格。
