我正在使用 Delphi 2010、Indy 10.5.8（svn 版本）和来自chuckbeasley 的 oAuth.pas。我能够使用应用程序密钥和应用程序秘密收集令牌，使用网页授权令牌并访问最终令牌。现在我必须使用 Linkedin 的 Share API 发布状态。我收到未经授权的回复。我的请求和响应如下。要求，

我无法评论您Authentication标头的内容，但您的 HTTP 请求的其余部分肯定不正确，这告诉我您没有TIdHTTP.Post()正确使用该方法。特别是，XML 已经过两次 url 编码（只有 Indy 会做其中之一），并且Content-Encoding标头是错误的。

我怀疑您犯了常见的新手错误，即使用 的TStrings重载版本发布 XML TIdHTTP.Post()，并预先对 XML 进行预编码。这些都行不通。您必须改用TStream重载版本，并且根本不对 XML 进行预编码。

正确的请求应该更像这样：

POST /v1/people/~/shares HTTP/1.0
Content-Type: text/xml; charset=utf-8
Content-Length: 571
Authorization: OAuth oauth_consumer_key="xxx",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1340438599",oauth_nonce="BB4C78E0A6EB452BEE0FAA2C3F921FC4",oauth_version="1.0",oauth_token="xxx",oauth_signature="Pz8%2FPz8%2FPz9ePzkxPyc%2FDD82Pz8%3D"
Host: api.linkedin.com
Accept: text/html, */*
Accept-Encoding: identity
User-Agent: Mozilla/3.0 (compatible; Indy Library)

<?xml version="1.0" encoding="UTF-8"?><share><comment>83% of employers will use social media to hire: 78% LinkedIn, 55% Facebook, 45% Twitter [SF Biz Times] http://bit.ly/cCpeOD</comment><content><title>Survey: Social networks top hiring tool - San Francisco Business Times</title><submitted-url>http://sanfrancisco.bizjournals.com/sanfrancisco/stories/2010/06/28/daily34.html</submitted-url><submitted-image-url>http://images.bizjournals.com/travel/cityscapes/thumbs/sm_sanfrancisco.jpg</submitted-image-url></content><visibility><code>anyone</code></visibility></share>

生成该请求的代码应如下所示：

var
  PostData: TMemoryStream;
begin
  PostData := TMemoryStream.Create;
  try
    WriteStringToStream(PostData, '<?xml version="1.0" encoding="UTF-8"?><share><comment>83% of employers will use social media to hire: 78% LinkedIn, 55% Facebook, 45% Twitter [SF Biz Times] http://bit.ly/cCpeOD</comment><content><title>Survey: Social networks top hiring tool - San Francisco Business Times</title><submitted-url>http://sanfrancisco.bizjournals.com/sanfrancisco/stories/2010/06/28/daily34.html</submitted-url><submitted-image-url>http://images.bizjournals.com/travel/cityscapes/thumbs/sm_sanfrancisco.jpg</submitted-image-url></content><visibility><code>anyone</code></visibility></share>', IndyUTF8Encoding);
    PostData.Position := 0;
    IdHTTP1.Request.ContentType := 'text/xml';
    IdHTTP1.Request.Charset := 'utf-8';
    IdHTTP1.Request.CustomHeaders.Values['Authorization'] := 'OAuth oauth_consumer_key="xxx",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1340438599",oauth_nonce="BB4C78E0A6EB452BEE0FAA2C3F921FC4",oauth_version="1.0",oauth_token="xxx",oauth_signature="Pz8%2FPz8%2FPz9ePzkxPyc%2FDD82Pz8%3D"';
    IdHTTP1.Post('http://api.linkedin.com/v1/people/~/shares', PostData);
  finally
    PostData.Free;
  end;
