如何使用Google Docs C#API访问公共电子表格？

我已经编写了一个C#程序，使用Google Docs.NET API将Google工作表读取到给定用户名、密码、电子表格名称和工作表名称的数据表中。这一切都很好，但编程模型似乎围绕着为电子表格服务提供一组凭证，然后削减结果提要以获得特定的电子表格/工作表，即

        SpreadsheetsService service = new SpreadsheetsService("Application-Name");
        service.setUserCredentials(userName, password);

        SpreadsheetQuery spreadsheetQuery = new SpreadsheetQuery();
        SpreadsheetFeed spreadsheetFeed = service.Query(spreadsheetQuery);

        SpreadsheetEntry spreadsheetEntry = (SpreadsheetEntry)(from entries in spreadsheetFeed.Entries
                                                               where entries.Title.Text == spreadsheetName
                                                               select entries).SingleOrDefault();

现在，我对扩展我的程序的功能感兴趣，可以从公开的谷歌电子表格中读取数据。也就是说，给定一个公共Google电子表格（例如“”）的URL，我想获得与该文档对应的SpreadsheetEntry对象

到目前为止，我使用的方法显然没有扩展到允许这样做，因此我想知道是否有人知道通过他们的API访问公共Google文档的正确方法？

Google文档列表API（参见ahab的答案）。

您可以简单地检索公共页面，然后解析行的HTML源代码

电子表格网格-列标签：

<table class="waffle" cellspacing="0" cellpadding="0">

<thead><tr>
<th class="row-header freezebar-top-left"></th>
<th style="width:120px" class="column-headers-background">A</th>
<th style="width:120px" class="column-headers-background">B</th>
<th style="width:120px" class="column-headers-background">C</th>
</tr></thead>

<tbody>

请注意id参数。您必须从html源代码中提取它，如下所示：

 ...
 var mergedConfig = {"formToken":"Kg2uOS1UniIe0yFks5zcDZDsGQ=","formStatus":false,"id":"tA6wDCJME0C-F342ieQghNA.PREF_08255578241116458508.3736592253424693644",

我过去常常捕获包括SSL加密消息在内的通信。

我试图读取一个包含多个选项卡的电子表格，而当我实现这些其他答案（即直接向页面发出web请求）时返回的html和javascript几乎无法读取。在进一步挖掘之后，我发现如果你真的想在不必处理任何OAuth内容的情况下获得一个公共Google电子表格的值，你首先需要转到，创建一个项目，转到仪表板，转到凭据，单击“创建凭据”，并设置一个新的服务帐户密钥（选择json并保存json文件。然后您可以使用它获取任何公共电子表格）：

<td class="g-0-GjugEgs2">3600001</td>
<td class="g-0-GjugEgs2">2012</td>
<td class="g-0-GjugEgs2">2013</td>
</tr>
