Everybody is good, small white a c, practice writing HTTP server, the code is as follows:
Problem;
The following code to compile a good run in the CMD window after,
1. Enter http://localhost:8088/test9.html in the browser, test9. HTML file doesn't exist,
Is meant to the browser output error message: "error! Check the request file name and the way!" , but the browser is a blank, but in the CMD debugging output, there is a HTTP poison
Discussion output string ah, as shown in figure 1 below, could you tell me which line of code is out of the question

2. Enter http://localhost:8088/test.html in the browser, the test. The HTML file exists, but the file content is not complete output
As shown in figure 2, can you tell me where the problem is,
