Question

尝试使用他们的api访问Google电子表格。按照他们的例子，代码不起作用，并且它不明显的原因。我所要做的就是连接，我不断收到同样的错误。这是他们的代码设置截至4/15/10。任何人都可以提出任何关于我做错的建议吗？代码：

using System;
using Google.GData.Client;
using Google.GData.Extensions;
using Google.GData.Spreadsheets;




namespace google_spreadsheet
{
    class Program
    {
        static void Main(string[] args)
        {
            SpreadsheetsService myService = new SpreadsheetsService("MySpreadsheet" );
            myService.setUserCredentials("account@gmail.com", "xxxxxxx");
            string token1 = myService.QueryClientLoginToken();
            Console.WriteLine("token is {0}", token1);
            Console.ReadLine();
            SpreadsheetQuery query = new SpreadsheetQuery();
            SpreadsheetFeed feed = myService.Query(query);
           Console.WriteLine("list");
            foreach (SpreadsheetEntry entry in feed.Entries)
            {
                Console.WriteLine("Value: {0}", entry.Title.Text);

当我运行它时，它会在myService.Query语句中出现错误，并出现以下错误：

Google.GData.Client.GDataRequestException was unhandled

然而，我可以拿走网址 http://spreadsheets.google.com/feeds/spreadsheets/private/full 并使用我的用户名/密码手动输入，它工作正常。有什么建议？谢谢岩石砂光机

Answer 1

我和Mono有一个similar problem。在我的情况下，SSL使用的证书存在问题。

Answer 2

我相信这是因为你没有在文档查询对象中指定Uri 试试这个

DocumentsService service = new DocumentsService("appName");
service.Credentials = new GDataCredentials("email@gmail.com", "password");

DocumentQuery query = new DocumentQuery("http://docs.google.com/feeds/default/private/full/-/contents");
query.Categories.Add(DocumentsListQuery.SPREADSHEETS);

var spreadsheets = service.Query(query).Entries.Cast<DocumentEntry>();

无法连接C＃和谷歌电子表格API
