来自此ios客户端应用程序<empty>的请求被阻止

Question

我尝试使用Google Sheets API，并且这样做如下：

var service = GTLRSheetsService()
let query = GTLRSheetsQuery_SpreadsheetsValuesGet.query(withSpreadsheetId: SpreadSheetIdentifier, range: SpreadSheetRange)
service.apiKey = SpreadSheetApiKey
service.executeQuery(query, delegate: self, didFinish: #selector(displayResultWithTicket(ticket:finishedWithObject:error:)))

但是当我调用该函数时出现错误：

  

此ios客户端应用程序<empty>的请求被阻止。

我想念什么？

我的Google表格可以访问具有链接的任何人。
