If you have a blog you might know about the MetaWeblog API. I implemented it for Tech Head Brothers portal to be able to post news from a client. Today I am using Live Writer to post on my blog and I also wanted to have the possibility to post news on the new version of Tech Head Brothers portal but with pictures and without the usage of a ftp server.
Checking the API I found a new method that I had not implemented: newMediaObject.
metaWeblog.newMediaObject (blogid, username, password, struct) returns struct
The blogid, username and password params are as in the Blogger API.
The struct must contain at least three elements, name, type and bits.
name is a string, it may be used to determine the name of the file that stores the object, or to display it in a list of objects. It determines how the weblog refers to the object. If the name is the same as an existing object stored in the weblog, it may replace the existing object.
type is a string, it indicates the type of the object, it's a standard MIME type, like audio/mpeg or image/jpeg or video/quicktime.
bits is a base64-encoded binary value containing the content of the object.
The struct may contain other elements, which may or may not be stored by the content management system.
If newMediaObject fails, it throws an error. If it succeeds, it returns a struct, which must contain at least one element, url, which is the url through which the object can be accessed. It must be either an FTP or HTTP url.
I defined in the interface two struct as following:
public struct MediaObjectUrl
public string url;
public struct MediaObject
public string name;
public string type;
public byte bits;
Added the method in the IMetaWeblog interface:
Description="Add a media object to a post using the "
+ "metaWeblog API. Returns media url as a string.")]
And finally the following implementation:
/// Post a media object.
/// <param name="blogid">The blogid.</param>
/// <param name="username">The username.</param>
/// <param name="password">The password.</param>
/// <param name="mediaObject">The media object.</param>
/// <returns>MediaObjectUrl defining the url of the media</returns>
public MediaObjectUrl newMediaObject(string blogid,
if (!ValidUser(username, password))
throw new XmlRpcFaultException(0, "You have no right to do that.");
string filename = Path.Combine(HttpContext.Current.Request.PhysicalApplicationPath,
"images/" + mediaObject.name);
MediaObjectUrl mediaObjectUrl = new MediaObjectUrl();
mediaObjectUrl.url = ConfigurationManager.AppSettings["BlogUrl"] +
The good point now is that I am able to let the authors of the site post news with embeded pictures without managing a ftp server.
