Question

脚本的其中一个步骤是获取有关城市当前天气的信息。但是有时，如果我要查找，则在API数据库中找不到城市名称，这会导致完全暂停脚本其余部分的错误。我想知道我可以调整什么，以便在搜索城市时出现错误，它将跳至脚本的下一步。

function TudoCompleto() {
  var spreadsheet = SpreadsheetApp.getActive();

//Clima
  spreadsheet.getRange('Monster!A1').activate();
  spreadsheet.getCurrentCell().setFormula('=IMPORTXML(\'Clima\'!F20,"//*[@id=\'page_team_1_block_venue_info_3\']/div/div[1]/dl/dt")');
  spreadsheet.getRange('Clima!F21:F45').activate();
  spreadsheet.getRange('Monster!A1:A25').copyTo(spreadsheet.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);

//Clima 2
  spreadsheet.getRange('Monster!A1').activate();
  spreadsheet.getCurrentCell().setFormula('=IMPORTXML(\'Clima\'!F20,"//*[@id=\'page_team_1_block_venue_info_3\']/div/div[1]/dl/dd")');
  spreadsheet.getRange('Clima!G21:G44').activate();
  spreadsheet.getRange('Monster!A1:A24').copyTo(spreadsheet.getActiveRange(), SpreadsheetApp.CopyPasteType.PASTE_VALUES, false);

//CLIMA  
  spreadsheet.getRange('Clima!A3:B8').activate();
  spreadsheet.getActiveRangeList().clear({contentsOnly: true, skipFilteredRows: true});

  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName("Clima");
  var apiKey = "MY API KEY"; // Or you can try my key

  var cityName = sheet.getRange("A1").getValue();
  // Go to https://openweathermap.org, register and get a free API key
  var apiCall = "api.openweathermap.org/data/2.5/weather?q=" + cityName +"&appid=" + apiKey;

  var response = UrlFetchApp.fetch(apiCall);
  var data = JSON.parse(response.getContentText());
  Logger.log(response.getContentText());

  var weather = data["weather"][0]; //It's an array
  var sys = data["sys"];
  var main = data["main"]
  var location = data["name"];
  var country = sys["country"];
  var weatherDesc = weather["main"];
  var temp = main["temp"];
  var minTemp = main["temp_min"];
  var maxTemp = main["temp_max"];

  var weatherData = [
    ["Location:", location],
    ["Country:", country],
    ["Weather:", weatherDesc],
    ["Teaperture:", temp],
    ["Min Temp:", minTemp],
    ["Max Temp:", maxTemp]
  ];

  sheet.getRange(3, 1, weatherData.length, weatherData[0].length).setValues(weatherData);



//The API Call works
// The Data will be retrieved like below JSON file.
//{"coord":{"lon":139,"lat":35},
//"sys":{"country":"JP","sunrise":1369769524,"sunset":1369821049},
//"weather":[{"id":804,"main":"clouds","description":"overcast clouds","icon":"04n"}],
//"main":{"temp":289.5,"humidity":89,"pressure":1013,"temp_min":287.04,"temp_max":292.04},
//"wind":{"speed":7.31,"deg":187.002},
//"rain":{"3h":0},
//"clouds":{"all":92},
//"dt":1369824698,
//"id":1851632,
//"name":"Shuzenji",
//"cod":200}


  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet(); // planilha ativa
     var sheet = spreadsheet.getSheetByName("Clima"); 

  for (var i = 1; i < 10; i++) {

    var cel = "H"+ i //

      if (sheet.getRange(cel).getValue() != "")  {   

         for (var u = 1; i < 1000; u++) {
            var cel2 = "M"+ u //

             if (sheet.getRange(cel2).getValue() == "")  { 

                 sheet.getRange("M"+u).setValue(sheet.getRange(cel).getValue());
                 break;
             };
      }
   }
};
  spreadsheet.getRange('Monster!A1').activate();
  spreadsheet.getActiveRangeList().clear({contentsOnly: true, skipFilteredRows: true});
  spreadsheet.getRange('Clima!F16').activate();
  spreadsheet.getActiveRangeList().clear({contentsOnly: true, skipFilteredRows: true});
}

当API找不到我要找的城市时，该错误会在第41行发生（var response = UrlFetchApp.fetch（apiCall）;）

如果发生此错误，我希望不再暂停脚本，而是从第83行继续（var电子表格= SpreadsheetApp.getActiveSpreadsheet（）; // planilha ativa）

使用UrlFetchApp参数检查是否返回有效响应：

muteHttpExceptions：布尔值：如果为true，则如果fetch不抛出异常响应代码表示失败，而是返回HTTPResponse。默认值为false.muteHttpExceptions

[https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app][1]

options = { 'muteHttpExceptions' : true}
var response = UrlFetchApp.fetch(apiCall, options)
if (reponse != 404){ code block to do if good response till line 83}
line 83

检查作为错误响应对象得到的结果。但是错误响应应该是404。

如果出现错误，请跳至下一步以编写Google脚本
