Image with HTTPserver

by **Manu** » 05 Aug 2009, 15:26

Hello,

I tried to add an image into the HTML with the HTTPTimeserver sample, but it doesn't work.

See code below, I added img tag:

std::ostream& ostr = response.send();

ostr <<
"<html>\n"
"<head>\n"
"<title>POCO Form Server Sample</title>\n"
"</head>\n"
"<body>\n"
"<h1>POCO Form Server Sample</h1>\n"
"<h2>GET Form</h2>\n"
"<img src=\"/myImage.png\" height=\"267\" width=\"400\" />\n" "<form method=\"GET\" action=\"/form\">\n"
.
.
.

The question is : How to make that?

You need to add a request handler for the image that sends back the image file.

In the simplest case, you add a request handler which simply does a

Code: Select all: response.sendFile("myImage.png", "image/png");

and add the following code to your request handler factory:

Code: Select all: if (uri.getPath() == "/myImage.png") return new MyImageHandler;

If you have to serve lots of different images and style sheets, etc., however, you might want to implement this in a generic way. In this case you need to implement a translation from URI paths to filesystem paths (take care of ".." path segments in the URI and trailing "." in the filesystem on Windows) and a mapping from file name extensions to MIME types.
