iPhone开发应用中ASIFormDataRequest POST操作架构设计是本文哟啊介绍的内容，主要是来讲述ASIFormDataRequest的POST操作架构设计，方法由自己定义。内容主要是基于代码来实现，来看详细代码。

//开启iphone网络开关
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
ASIFormDataRequest *request = [[ASIFormDataRequest alloc] initWithURL:[NSURLURLWithString:host]];
//超时时间
request.timeOutSeconds = 30;
//定义异步方法
[request setDelegate:self];
[request setDidFailSelector:@selector(requestDidFailed:)];
[request setDidFinishSelector:@selector(requestDidSuccess:)];

//用户自定义数据   字典类型  （可选）
request.userInfo = [NSDictionary dictionaryWithObject:method forKey:@"Method"];
//post的数据
[request appendPostData:[body dataUsingEncoding:NSUTF8StringEncoding]];
//开始执行
[request startAsynchronous];
//执行成功
- (void)requestDidSuccess:(ASIFormDataRequest *)request
{
//获取头文件
NSDictionary *headers = [request responseHeaders];
//获取http协议执行代码
NSLog(@"Code:%d",[request responseStatusCode]);
if ([delegaterespondsToSelector:@selector(OARequestSuccessed:withResponse:WithData:withHeaders:)])
{
//执行委托操作  （架构设计   自选）
[delegate OARequestSuccessed:method withResponse:[request responseString]WithData:[request responseData] withHeaders:headers];
}
//清空
if (request)
{
[request release];
}
//关闭网络
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
｝
//执行失败
- (void)requestDidFailed:(ASIFormDataRequest *)request{

//获取的用户自定义内容

NSString *method = [request.userInfo objectForKey:@"Method"];
//获取错误数据
NSError *error = [request error];
if ([delegate respondsToSelector:@selector(OARequestFailed:withError:)])
{
//执行委托 将错误数据传其他方式（架构设计   自选）
[delegate OARequestFailed:method withError:error];
}
if (request)
{
[request release];
}
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
}

//执行成功函数

- (void)OARequestSuccessed:(NSString *)method withResponse:(NSString *)response WithData:(NSData *)data withHeaders:(NSDictionary *)headers
{
NSString *responseStr = [[[NSString alloc] initWithData:dataencoding:NSUTF8StringEncoding] autorelease];
//服务返回post后的数据
NSLog(@"response:\n%@",responseStr);
}

//执行失败函数
- (void)OARequestFailed:(NSString *)method withError:(NSError *)error
{
NSLog(@"Error:%@",error);
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"出错了" message:@"网络连接失败, 请稍后重试."
delegate:nil cancelButtonTitle:@"好的" otherButtonTitles:nil];
[alert show];
[alert release];
}
