无法从Iphone制作Json Request正文

本文介绍了无法从Iphone制作Json Request正文的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我是.Net软件开发人员。我为用户验证创建了一个WCF Rest API以下是它的签名。

I am a .Net Software developer .I have Created a WCF Rest API for User Validation Following is its signature.

[OperationContract]
    [WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare,
        UriTemplate = "/Validate", Method = "POST")]
    UserListResponse ValidateUser(Login obj);

在fiddler中使用以下Request Body

It is working fine in fiddler with following Request Body

{"Username":"admin",Password:"111"}

我的问题是，无法使用http post方法从Iphone访问它，但它在Android Http post方法中运行良好。

My problem is, it is not accessible from Iphone using http post method but it is working fine in Android Http post method.

以下是我的代码：

NSError *theError = nil;

NSArray *keys = [NSArray arrayWithObjects:@"Username", @"Password", nil];

NSArray *objects = [NSArray arrayWithObjects:@"admin", @"111", nil];

NSDictionary *jsonDictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

NSString *myJSONString =[jsonDictionary JSONRepresentation];

NSData *myJSONData =[myJSONString dataUsingEncoding:NSUTF8StringEncoding];

NSLog(@"myJSONString :%@", myJSONString); 

NSLog(@"myJSONData :%@", myJSONData); 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://192.168.1.192/ShopMonkeyService/ShopMonkey.svc/Validate"]];

[request setHTTPBody:myJSONData]; 

[request setHTTPMethod:@"POST"];

NSURLResponse *theResponse =[[NSURLResponse alloc]init];

NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&theError];   

NSLog(@"response : %@", theResponse);

NSLog(@"error : %@", theError);

NSLog(@"data : %@", data);

NSMutableString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

NSLog(@"string: %@", string);

NSDictionary *jsonDictionaryResponse = [string JSONValue];

NSLog(@"dic: %@", jsonDictionaryResponse);

以下是我的回复错误：

在抛出'NSException'的实例后终止调用

terminate called after throwing an instance of 'NSException'

推荐答案

对于按值传递JSON的密钥你应该进去这个方向..

for Key by value passing in JSON your should go in this direction ..

    NSArray *keys = [NSArray arrayWithObjects:@"username", @"password", @"preference", @"uid", nil];
NSArray *objects = [NSArray arrayWithObjects:@"accuser", @"accpass", @"abc_region", @"100", nil];
NSDictionary *theRequestDictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

NSURL *theURL = [NSURL URLWithString:@"http://url.com/request.php"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10.0f];
[theRequest setHTTPMethod:@"POST"];

[theRequest setValue:@"application/json-rpc" forHTTPHeaderField:@"Content-Type"];
NSString *theBodyString = [[CJSONSerializer serializer] serializeDictionary:theRequestDictionary];
NSLog(@"%@", theBodyString);
NSData *theBodyData = [theBodyString dataUsingEncoding:NSUTF8StringEncoding];
// NSLog(@"%@", theBodyData);
[theRequest setHTTPBody:theBodyData];

NSURLResponse *theResponse = NULL;
NSError *theError = NULL;
NSData *theResponseData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&theResponse error:&theError];
NSString *theResponseString = [[[NSString alloc] initWithData:theResponseData encoding:NSUTF8StringEncoding] autorelease];
NSLog(theResponseString);
NSDictionary *theResponseDictionary = [[CJSONDeserializer deserializer] deserialize:theResponseString];
NSLog(@"%@", theResponseDictionary);
NSString *theGreeting = [theResponseDictionary objectForKey:@"greeting"];
[self setValue:theGreeting forKey:@"greeting"];

只需检查..
还有一件事你会找到这个文件 CJSONSerializer 从这里

Just and check .. one more thing u will find this file CJSONSerializer from here CJSONSerializer file path
