我以前从未使用stat()
过,也不知道出了什么问题。
我有一个接受 GET 请求并解析文件路径的服务器程序。我在发送 GET 请求的同一目录中也有一个客户端程序。服务器程序正在接受 GET 请求并正确解析文件路径。两个程序所在目录的路径是:~/asimes2/hw2/
如果我有客户端程序发送:GET /Makefile HTTP/1.0\r\n\r\n
然后服务器程序收到同样的东西。我有两个printf()
s 来确认我正在正确解析文件路径并查看完整路径。它输出:
File path = '/Makefile'
Full path = '~/asimes2/hw2/Makefile'
NOT FOUND!
Makefile
确实存在于~/asimes/hw2
. 这是代码:
// Alex: Parse the PATH from the GET request using httpGet
char* filePath, * pathStart = strchr(httpGet, '/');
if (pathStart != NULL) {
// Alex: Increment to the first '/'
httpGet += (int)(pathStart-httpGet);
// Alex: Assuming " HTTP" is not a part of the PATH, this finds the end of the PATH
char* pathEnd = strstr(httpGet, " HTTP");
if (pathEnd != NULL) {
int endLoc = (int)(pathEnd-httpGet);
filePath = (char*)malloc((endLoc+1)*sizeof(char));
strncpy(filePath, httpGet, endLoc);
filePath[endLoc] = '\0';
}
else errorMessageExit("The GET request was not formatted as expected");
}
else errorMessageExit("The GET request was not formatted as expected");
printf("File path = '%s'\n", filePath);
char* fullPath = (char*)malloc((14+strlen(filePath))*sizeof(char));
strcpy(fullPath, "~/asimes2/hw2");
strcat(fullPath, filePath);
printf("Full path = '%s'\n", fullPath);
struct stat fileStat;
if (stat(fullPath, &fileStat) == -1) printf("NOT FOUND!\n");
else printf("HOORAY\n");
