Question

我是Google Apps用户，尝试在VB.NET中编写功能，将文件上传到特定用户的Google文档帐户（当然，这些都在我的Google Apps域中）。我尝试使用Google GData API for ASP.NET，但遗憾的是，根据Google员工的说法，此库不会在网址中添加xoauth_requestor_id ...

我不知道如何添加它，但不知道如何手动构建HTTP POST请求，尤其是关于如何发送Google在其网站上提到的XML有效负载如下所示......

以下是我尝试使用以下代码手动构建针对Google文档的HTTP POST：Google GData API page

此代码返回401-Unauthorized错误：

Protected Sub UploadToGDocs2() 
        Dim str As String = "" 
        'The commented-out code below is the HTTP POST code mentioned on 
        'http://code.google.com/apis/accounts/docs/OAuth.html#tokensGADomains

        'POST /feeds/documents/private/full?xoauth_requestor_id=j.doe%40example.com HTTP1.1

        '  <atom:title>Company Perks</atom:title> 
        '</atom:entry 

       'Here's my attempt to build the HTTP POST command in .NET 
        Dim web As New System.Net.WebClient() 
        web.Headers.Add("Host", "docs.google.com") 
        web.Headers.Add("Content-Type", "application/atom+xml") 
        web.Headers.Add("Authorization", "OAuth") 
        Dim keyval As New StringBuilder 
        keyval.Append("oauth_version=1.0") 
        keyval.Append("&oauth_nonce=1c4fbbe4387a685829d5938a3d97988c")

       'I have no idea what to do with the XML code below. Where does it go? 

        keyval.Append("&<atom:entry xmlns:atom='http://www.w3.org/2005/

        keyval.Append("<atom:title>Company Perks</atom:title>") 
        keyval.Append("</atom:entry") 
        Dim d As Byte() = 
System.Text.Encoding.ASCII.GetBytes(keyval.ToString) 
        Dim myUrl As String = "https://docs.google.com/feeds/someone 
%40myDomain.com/private/full?xoauth_requestor_id=someone 
%40myDomain.com" 
        Dim res As Byte() = web.UploadData(myUrl.ToString, "POST", d) 
        Response.Write(System.Text.Encoding.ASCII.GetString(res)) 
    End Sub
