具有图像的Web服务器HTML响应 [英] Web server HTML response with image
问题描述
您好，
我有一个Web服务器，当有人通过Web浏览器向其发送请求时，它会返回一条消息。但我想制作一个复杂的html，需要一个图像。
我发送回复的代码是：
Hello,
I have a web server that returns a message when someone sends a request to it through a web browser. But I want to make a complex html, which needs an image.
My code to send the response is:
Dim responseString As String = "<html>Welcome to my web server<img src = ""..."" alt = ""no image""></html>"
'So the html is <html>Welcome to my web server<img src = "..." alt = "no image"></html>
Dim buffer() As Byte = System.Text.Encoding.UTF8.GetBytes(responseString)
response.ContentLength64 = buffer.Length
Dim output As System.IO.Stream = response.OutputStream
output.Write(buffer, 0, buffer.Length)
但我不能获取要显示的图像。而是显示替代文本。
图像的绝对路径是C：\ Users \ Rixterz \Desktop\test\test\bin\debug \ image。 jpeg
这个应用程序的路径是C：\ Users\Rixterz \Desktop\test\test\bin\debug \ test.vshost
所以我以为img src =../ image.jpeg但替代文字不会消失！
请帮忙！
But I cannot get the image to display. Instead, the alt text is shown.
The absolute path to the image is C:\Users\Rixterz\Desktop\test\test\bin\debug\image.jpeg
This application's path is C:\Users\Rixterz\Desktop\test\test\bin\debug\test.vshost
So I thought the img src = "../image.jpeg" but the alt text won't go away!
Please help!
推荐答案
您需要使用HTTP响应发送适当的 content-type 。请参阅：
http://en.wikipedia.org/wiki/Content_type [< a href =http://en.wikipedia.org/wiki/Content_typetarget =_ blanktitle =New Window> ^ ]。
此处维护标准内容类型： http://www.iana.org/assignments /media-types/media-types.xhtml [ ^ ]。
图片类型在这里： http://www.iana.org/assignments/media-types/media-types.xhtml#image [ ^ ]。

You need to send appropriate content-type with the HTTP response. Please see:
