NSURLRequest和NSURLConnection的Core Foundation等价物

Question

我知道NSUrl已经连接到CFUrl.什么是Core Foundation等价物NSURLRequest,NSURLConnection所以我可以使用纯C对CFUrl对象做些什么？

Answer 1

有没有直接等同NSURLRequest与NSURLConnection在核心基础,但你可以使用较低级别的CFHTTP功能CFNetwork的.

例如,

CFHTTPMessageRef myRequest = CFHTTPMessageCreateRequest(kCFAllocatorDefault,
        requestMethod, myUrl, kCFHTTPVersion1_1);
CFHTTPMessageSetBody(myRequest, bodyData);
CFHTTPMessageSetHeaderFieldValue(myRequest, headerField, value);

CFReadStreamRef myReadStream = CFReadStreamCreateForHTTPRequest(kCFAllocatorDefault, myRequest);

CFReadStreamOpen(myReadStream);

CFHTTPMessageRef myResponse = CFReadStreamCopyProperty(myReadStream, kCFStreamPropertyHTTPResponseHeader);
