本文介绍如何利用ASIFormDataRequest发起POST请求，并设置请求头为application/json类型，通过将NSMutableDictionary转换为JSON字符串作为POST数据发送。

NSString *summary=summaryURl;
NSURL *urlStr=[NSURL URLWithString:summary];
summaryRequest=[ASIFormDataRequest requestWithURL:urlStr];
[summaryRequest setRequestMethod:@"POST"];
[summaryRequest addRequestHeader:@"Content-Type" value:@"application/json"];
summaryRequest.tag=ETSummaryRequestTag;;
NSMutableDictionary *mutaDict=[NSMutableDictionary dictionary];
[mutaDict setObject: [NSNumber numberWithInt:ShareApp.appUserId] forKey:@"user_id"];
NSString *jsonString=[mutaDict JSONRepresentation];
[summaryRequest appendPostData:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
summaryRequest.delegate=self;
[summaryRequest startAsynchronous];
[UIApplication sharedApplication].networkActivityIndicatorVisible=YES;
