使用其 public URL 和 .net 库修改 google 电子表格，无需授权

Question

我有一个 google 电子表格 URL 与我共享 "everyone that have link is able to edit" 权限 我需要能够将 smth 放入它的单元格中，但我不知道该怎么做，google 文档对此没有帮助。 有任何想法吗？ Google 文档共享 url 是 https://docs.google.com/spreadsheets/d/1oKSViNtjtaKjdckJBiIQEZHgbUImnmiNOCQsYpIGdl0/edit?usp=sharing

我可以通过网络浏览器对它做任何事情，所以我可能可以用 .net 库来做吗？

Answer 1

这对我有用：

1. 在 https://console.developers.google.com 创建一个新的 google 项目并创建一个服务帐户密钥。
2. 添加"Drive api"

3. 写一些代码

   static void DoSheet()
   {
       var certificate = new X509Certificate2(@"cert.p12", "notasecret", X509KeyStorageFlags.Exportable);
       const string scope = "https://spreadsheets.google.com/feeds https://docs.google.com/feeds";
       var credential = new
       ServiceAccountCredential(
           new ServiceAccountCredential.Initializer("project email")
           {
               Scopes = new[] { scope }
           }.FromCertificate(certificate));
   
       var requestFactory = new GDataRequestFactory("App name");
       bool success = credential.RequestAccessTokenAsync(System.Threading.CancellationToken.None).Result;
       requestFactory.CustomHeaders.Add($"Authorization: Bearer {credential.Token.AccessToken}");
   
       var service = new SpreadsheetsService("myproject-id") {RequestFactory = requestFactory};
       var path = $"https://spreadsheets.google.com/feeds/worksheets/1oKSViNtjtaKjdckJBiIQEZHgbUImnmiNOCQsYpIGdl0/private/full";
       var query = new WorksheetQuery(path);
       var feed = service.Query(query);
       var worksheet = (WorksheetEntry)feed.Entries[0];
       var cellQuery = new CellQuery(worksheet.CellFeedLink);
       var cellFeed = service.Query(cellQuery);
       // Iterate through each cell, printing its value.
       foreach (var atomEntry in cellFeed.Entries)
       {
           var cell = (CellEntry) atomEntry;
           if (cell.Title.Text == "A1")
           {
               cell.InputValue = "200";
               cell.Update();
           }
           else if (cell.Title.Text == "B1")
           {
               cell.InputValue = "=SUM(A1, 200)";
               cell.Update();
           }
       }
   }
   

这里的技巧是获取 Sheet Id 并在查询 url 中使用它，之后 /private/full
