我想通过 C# 使用 HttpWebRequest 为 Google Plus 帐户上传个人资料照片。如何在此帖子查询的页面源中查找方法？我正在使用 Web Inspector（Chrome 开发人员工具），但无法找到单击“设置个人资料照片”按钮后执行的代码。
这里上传照片的代码，我在网上找到的：
public bool UploadPhoto( Photo photo, string accountLine, string googleCookie )
{
try
{
string query, upload_id;
// проверка ошибок
if( photo.Size == 0 ) return false;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create( "https://plus.google.com/_/upload/photos/resumable?authuser=0" );
string content = "{\"protocolVersion\":\"0.8\",\"createSessionRequest\":{\"fields\":[{\"external\":{\"name\":\"file\",\"filename\":\"image-8453.jpg\",\"put\":{},\"size\":" +
photo.Size.ToString() + "}},{\"inlined\":{\"name\":\"async_thumbnail\",\"content\":\"false\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"auto_create_album\",\"content\":\"profile_photos.draft\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"disable_asbe_notification\",\"content\":\"true\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"enable_face_detection\",\"content\":\"true\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"use_upload_size_pref\",\"content\":\"true\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"title\",\"content\":\"image-8453.jpg\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"addtime\",\"content\":\"1341478011235\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"batchid\",\"content\":\"1341477814870\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"album_name\",\"content\":\"5 \\u043b\\u0438\\u043f\\u043d\\u044f 2012 \\u0440.\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"album_abs_position\",\"content\":\"0\",\"contentType\":\"text/plain\"}},{\"inlined\":{\"name\":\"client\",\"content\":\"es-profile-signup\",\"contentType\":\"text/plain\"}}]}}";
byte[] bcontent;
string header = "Cookie: " + googleCookie;
bcontent = Encoding.Default.GetBytes( content );
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
req.ContentLength = bcontent.Length;
req.UserAgent = userAgent;
req.Referer = "https://plus.google.com/u/0/_/notifications/frame?sourceid=1&hl=ru&origin=https%3A%2F%2Fwww.google.com&uc=1&jsh=m%3B%2F_%2Fabc-static%2F_%2Fjs%2Fgapi%2F__features__%2Frt%3Dj%2Fver%3DVO1wk6ea0_A.en.%2Fsv%3D1%2Fam%3D!OgKRzknZ1ASBPEY3DA%2Fd%3D1";
req.Headers.Add( header );
req.GetRequestStream().Write( bcontent, 0, bcontent.Length );
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
StreamReader sr = new StreamReader( resp.GetResponseStream() );
content = sr.ReadToEnd();
Match m = Regex.Match( content, "\"url\":\"(?<url>[^\"]+)\"" );
if( !m.Success ) return false;
query = m.Groups[ "url" ].Value;
m = Regex.Match( content, "upload_id\":\"(?<upload_id>[^\"]+)\"" );
if( !m.Success ) return false;
upload_id = m.Groups[ "upload_id" ].Value;
req = (HttpWebRequest)WebRequest.Create( query );
req.ContentLength = photo.Size;
req.Method = "POST";
req.ContentType = "application/octet-stream";
req.Headers.Add( "Accept-Charset", "utf-8" );
req.Headers.Add( "Origin", "plus.google.com" );
req.Headers.Add( "X-GUploader-No-308", "yes" );
req.Headers.Add( "X-HTTP-Method-Override", "PUT" );
req.Headers.Add( header );
req.Accept = "*/*";
req.UserAgent = userAgent;
req.GetRequestStream().Write( photo.Data, 0, photo.Size );
resp = (HttpWebResponse)req.GetResponse();
return true;
}
catch( Exception ex )
{
Log( accountLine + ": Error with uploading photo: " + ex.Message );
return false;
}
}
但是此代码在执行第二个查询时会生成异常“方法不允许”。
另外，我已经有登录和发布文本的成功代码。
