为什么这个帖子不起作用？
这是我的代码片段：
NSString *post = @"from=A&name=B&[email protected]&messaggio=MESSAGE&codHidden=-1";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"http://www.mysite.com/page.php"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSData *urlData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSLog(@"Succeeded! Received %d bytes of data",[urlData length]);
NSString *outputdata = [[NSString alloc] initWithData:urlData encoding:NSASCIIStringEncoding];
NSLog(@"%@", outputdata);
它调用一个向我发送电子邮件的 php 页面...
这段代码有任何错误吗？
似乎不起作用...
谢谢
this is my snippet:
NSString *post = @"from=A&name=B&[email protected]&messaggio=MESSAGE&codHidden=-1";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"http://www.mysite.com/page.php"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSData *urlData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSLog(@"Succeeded! Received %d bytes of data",[urlData length]);
NSString *outputdata = [[NSString alloc] initWithData:urlData encoding:NSASCIIStringEncoding];
NSLog(@"%@", outputdata);
It call a php page that send me an email...
Is there any errors in this code?
Does not seem to work...
thanks

这是同步/异步问题吗？如果是这样，请使用委托模式并异步访问数据。您可以发布您看到的任何错误（或服务器的响应字符串）吗？
编辑：由于您没有对返回的错误执行任何有用的操作，因此更改您的类以异步执行请求。之前在此处发布了对此问题的一个很好的答案。一旦你实现了
didFailWithError，你就会有一个更好的画面。Is it a Synchronous/Asynchronous problem? If so, use the delegate-pattern and access the data asynchronously. Could you post any errors you see (or the server's response string)?
EDIT: Since you're not doing anything useful with the error returned, change your class to do the request asynchronously. A great answer to this was previously posted here. Once you implement
didFailWithErroryou'll have a better picture.尝试将 NSASCIIStringEncoding 更改为 NSUTF8StringEncoding
Try to change NSASCIIStringEncoding to NSUTF8StringEncoding
