Use standard IdEncoderMIME / IdDecoderMime from the Indy Misc palette. You have some methods for encoding streams.

使用Indy Misc调色板中的标准IdEncoderMIME / IdDecoderMime。您有一些编码流的方法。

You can use SimpleStorage, a XML storage based framework I created. You can download it from here.

您可以使用SimpleStorage,这是我创建的基于XML存储的框架。你可以在这里下载。

It was made to solve problems like yours. To do what you want you need a single line of code:

这是为了解决像你这样的问题。要做你想做的事,你需要一行代码:

SrcStorage.Ensure('Data').Filter('gzip').AsBinary.LoadFromStream(MemoryStream);

Not only it automatically base64 encodes the data but it also supports filter so you can gzip on the fly.

它不仅自动base64编码数据,而且还支持过滤器,因此您可以动态gzip。

So with three lines of code you can do it all:

因此,使用三行代码,您可以完成所有操作:

SrcStorage := CreateStorage('BinaryStorage'); SrcStorage.Ensure('Data').Filter('gzip').AsBinary.LoadFromStream(MemoryStream); SrcStorage.SaveToFile('Data.xml');

SrcStorage:= CreateStorage('BinaryStorage'); SrcStorage.Ensure( '数据')过滤器( '的gzip')AsBinary.LoadFromStream(MemoryStream的)。; SrcStorage.SaveToFile( 'data.xml中');

It uses OmniXML a very good delphi XML library. You can find all info on the download page.

它使用OmniXML一个非常好的delphi XML库。您可以在下载页面上找到所有信息。

I have done this using DIMimeStreams, encoding to a tStringStream, then placing the stream.datastring as the text portion of a specific element. If you want to add encryption, then I would add the routines found in LockBox to encrypt the stream prior to the MIME step. The latest version of LockBox, compiled for 2009 is available on the songbeamer website. You can also compress using just about any compression routine which compresses to a stream, and then run through the mime step.

我使用DIMimeStreams,编码为tStringStream,然后将stream.datastring作为特定元素的文本部分。如果要添加加密,那么我将添加LockBox中找到的例程,以便在MIME步骤之前加密流。最新版本的LockBox,于2009年编制,可在songbeamer网站上找到。您也可以使用几乎任何压缩到流的压缩例程进行压缩,然后运行mime步骤。
