iPhone의 RESTful 웹 서비스 : 데이터가 데이터베이스에 삽입되지 않았습니다.

Question

MAMP와 함께 제공되는 '셰이프'웹 서비스를 사용하여 튜토리얼을 시작했습니다. 이제는 나 자신을위한 서비스를 재창조하려고합니다. 나는 지금 해결책을 찾고 있거나 지난 5 시간 동안 문제를 디버깅하는 방법을 찾고있다. 필자는 PHP가 아니므로 디버그 또는 URL 응답을 출력 할 수있는 방법을 설정할 수 있는지 잘 모르겠습니다. 누구나 도움을 주시면 대단히 감사하겠습니다.

목표 - C 코드 :

NSString* serviceRootUrlString = @"http://localhost:8888/answers/Answers/"; 
NSURL* answerService = [NSURL URLWithString:serviceRootUrlString]; 
_database = [[Database alloc] initWithServiceUrl:answerService]; 

- (void)nextQuestionWithAnswer:(NSString *)answer andComment:(NSString *)comment 
{ 
    NSString* deviceId = [[UIDevice currentDevice] uniqueIdentifier]; 
    NSData* deviceIdAsData = [deviceId dataUsingEncoding:NSUTF8StringEncoding]; 
    NSString* deviceHash = [Database MD5Hash:deviceIdAsData]; 

    NSMutableDictionary* answerDictionary = [NSMutableDictionary dictionary]; 
    [answerDictionary setObject:deviceHash forKey:@"SetId"]; 
    [answerDictionary setObject:[NSNumber numberWithInt:(_currentQuestionNumber + 1)] forKey:@"QuestionId"]; 
    [answerDictionary setObject:answer forKey:@"Answer"]; 
    [answerDictionary setObject:comment forKey:@"Comment"]; 

    [_database insertRecordWithDictionary:answerDictionary]; 

    [self nextQuestion]; 
} 

- (BOOL)insertRecordWithDictionary:(NSDictionary *)recordDictionary 
{ 
    NSData* recordPropertyListData = [NSPropertyListSerialization dataFromPropertyList:recordDictionary format:NSPropertyListXMLFormat_v1_0 errorDescription:nil]; 

    NSMutableURLRequest* urlRequest = [NSMutableURLRequest requestWithURL:_serviceUrl]; 
    [urlRequest setHTTPMethod:@"POST"]; 
    [urlRequest setHTTPBody:recordPropertyListData]; 

    NSURLResponse* response = nil; 
    NSError* error = nil; 

    NSData* responseData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error]; 

    id propertyList = [NSPropertyListSerialization propertyListWithData:responseData options:NSPropertyListImmutable format:nil error:nil]; 

    NSDictionary* responseDictionary = (NSDictionary*)propertyList; 

    NSLog(@"New Record result: %@", responseDictionary); 

    if (error == nil) 
    { 
     return YES; 
    } 
    else 
    { 
     NSLog(@"Database Error: %@", [error description]); 

     return NO; 
    } 
}

:

NSData* responseData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error]; 
NSLog(@"Reponse: %@", [[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding] autorelease]); 

아이폰 OS 그냥 어딘가에 입력을 포함 HTML 양식을 HTML 파일을 생성하지 않고 체크 PHP는 응답하십시오. 이러한 입력에는 recordDictionary 변수와 같은 키와 값이 있어야합니다. 양식 작업은 serviceRootUrlString 변수의 POST 메소드와 같아야합니다. 내가 initWithData 것
