iPhone应用-JSON请求失败

Json格式如下，要发送请求到服务器，但是返回的是错误500。

{""firstName"":""Sharath K""lastName"":""babu""moMerchantAddresses"":[{""email"":""abc@abc.co.in""}]} >

谢谢您的帮助。

 NSMutableArray *objects =  [NSMutableArray  arrayWithObjects:@""Sharath""@""babu""@""[{""email"":""abc@abc.co.in""}]"" nil];        NSMutableArray *keys = [NSMutableArray arrayWithObjects:@""firstName""@""lastName""@""moMerchantAddresses"" nil];NSMutableDictionary  *jsonDict = [NSMutableDictionary dictionaryWithObjects:objects forKeys:keys];NSData *jsonData = [NSJSONSerialization dataWithJSONObject:jsonDict                                                   options:NSJSONWritingPrettyPrinted // Pass 0 if you don't care about the readability of the generated string                                                     error:nil];NSString *postLength = [NSString stringWithFormat:@""%d""[jsonData length]];ServiceInterface *service = [[ServiceInterface alloc] init];service.theDelegate = self;service.theSuccessMethod = @selector(responseMerchantCreationService:);service.theFailureMethod = @selector(requestFailedWithError:);[self addServiceInterfaceToServiceStack:service];NSString* stringURL  =  [kBase_URL stringByAppendingString:@""/merchant/create""];NSString* webStringURL  =  [stringURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];NSURL* url  =  [NSURL URLWithString:webStringURL];NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];[request setHTTPMethod:@""POST""];[request setValue:postLength forHTTPHeaderField:@""Content-Length""];[request setValue:@""application/json"" forHTTPHeaderField:@""Accept""];[request setValue:@""application/json"" forHTTPHeaderField:@""Content-Type""];[request setHTTPBody:jsonData];[request setTimeoutInterval:30.0f];NSLog(@""request file :: %@""request);[service startWithRequest:request];service = nil;

解决方案

NSMutableDictionary *emailDict = [[NSMutableDictionary alloc] initWithCapacity:0];[emailDict setObject:@""abc@abc.co.in"" forKey:@""email""];NSMutableArray *emailArr = [ [NSMutableArray alloc] init];[emailArr addObject:emailDict];NSMutableDictionary *mainDict = [[NSMutableDictionary alloc] initWithCapacity:0];[mainDict setObject:@""Sharath"" forKey:@""firstName""];[mainDict setObject:@""babu"" forKey:@""lastName""];[mainDict setObject:emailDict forKey:@""moMerchantAddresses""];

修改mainDict为：

NSData *jsonData = [ NSJSONSerialization dataWithJSONObject:mainDict options:NSJSONWritingPrettyPrinted // Pass 0 if you don't care about the readability of the generated string                                                         error:nil];
