这里的大部分信息都是指废弃的ASIHTTPREQUEST项目，所以请原谅我再次提出要求。
实际上，我需要刷磁条并发送轨道2数据到一个返回登记或notenrolled（取决于卡的状态...）的web服务。
所以我的数据简单地表示为
NSData * data = [通知对象];然后我需要将这个传递给一个url到
$ b $的顺序bexample/CardSwipe。 cfc？method = isenrolled& track2 = data 然后只收到一个响应字符串...
我搜索了一大堆，似乎有一些矛盾的答案，应该只用AFNetworking，RESTkit还是使用本地NSURL / NSMutableURLRequest协议完成。
解决方案在Objective-C中执行HTTP请求的选项可能有点吓人。对我来说一个很好的解决方案是使用 NSMutableURLRequest 。一个例子（使用ARC，所以YMMV）是： $ p $ - （NSString *）getDataFrom：（NSString *）url { NSMutableURLRequest * request = [[NSMutableURLRequest alloc] init]; [request setHTTPMethod：@GET]; [request setURL：[NSURL URLWithString：url]]; NSError * error = nil; NSHTTPURLResponse * responseCode = nil; NSData * oResponseData = [NSURLConnection sendSynchronousRequest：request returningResponse：& responseCode error：& error]; （[responseCode statusCode]！= 200）{ NSLog（@Error％@，HTTP status code％i，url，[responseCode statusCode]）; 返回零; } return [[NSString alloc] initWithData：oResponseData encoding：NSUTF8StringEncoding]; }

您的问题的标题和标记说POST，但您的示例URL将指示GET请求。在GET请求的情况下，上面的例子就足够了。对于POST，您可以按如下方式进行更改：
- （NSString *）getDataFrom：（NSString *）url withBody ：（NSData *）body { NSMutableURLRequest * request = [[NSMutableURLRequest alloc] init]; [request setHTTPMethod：@POST]; [request setHTTPBody：body]; [请求setValue：[NSString stringWithFormat：@％d，[body length]] forHTTPHeaderField：@Content-Length]; [request setURL：[NSURL URLWithString：url]]; / *与上述相同* / }
Most of the information here refers to the abandoned ASIHTTPREQUEST project so forgive me for asking again.
Effectively, I need to swipe a magnetic strip and send the track 2 data to a webservice that returns "enrolled" or "notenrolled" (depending on the status of the card...)
So my data comes in simply as
NSData *data = [notification object];And then I need to pass this to a url to the order of
example/CardSwipe.cfc?method=isenrolled&track2=data
And then just receive a response string...
I've searched a ton and there seems to be some conflicting answers as to whether this should be accomplished simply with AFNetworking, RESTkit, or with the native NSURL/NSMutableURLRequest protocols.
解决方案The options for performing HTTP requests in Objective-C can be a little intimidating. One solution that has worked well for me is to use NSMutableURLRequest. An example (using ARC, so YMMV) is:
- (NSString *) getDataFrom:(NSString *)url{ NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setHTTPMethod:@"GET"]; [request setURL:[NSURL URLWithString:url]]; NSError *error = nil; NSHTTPURLResponse *responseCode = nil; NSData *oResponseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&responseCode error:&error]; if([responseCode statusCode] != 200){ NSLog(@"Error getting %@, HTTP status code %i", url, [responseCode statusCode]); return nil; } return [[NSString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding]; }Update:
Your question's title, and tagging say POST, but your example URL would indicate a GET request. In the case of a GET request, the above example is sufficient. For a POST, you'd change it up as follows:
- (NSString *) getDataFrom:(NSString *)url withBody:(NSData *)body{ NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:body]; [request setValue:[NSString stringWithFormat:@"%d", [body length]] forHTTPHeaderField:@"Content-Length"]; [request setURL:[NSURL URLWithString:url]]; /* the same as above from here out */ }
