JSON在iOS中发布无法正常工作（.NET服务器）

-3

向.NET服务器发送请求无法正常工作。JSON在iOS中发布无法正常工作（.NET服务器）

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

NSURL *postURL = [NSURL URLWithString: @"SOME URL"]; 
NSError *error=nil; 
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:jsonDict options:0 error:&error]; 


NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: postURL 
                 cachePolicy: NSURLRequestUseProtocolCachePolicy 
                timeoutInterval: 60.0]; 

[request setHTTPMethod: @"POST"]; 
[request setValue: @"application/json" forHTTPHeaderField: @"Accept"]; 
[request setValue: @"application/json" forHTTPHeaderField: @"Content-Type"]; 
[request setValue:[NSString stringWithFormat:@"%d",[jsonData length]] forHTTPHeaderField:@"Content-Length"]; 
[request setHTTPBody: jsonData]; 

NSLog(@"JSON summary: %@", [[NSString alloc] initWithData:jsonData 
               encoding:NSUTF8StringEncoding]);

输出为：

{"CreatedBy":"","EmailAddress":"[email protected]","Zipcode":"","FirstName":"devan","DeviceCategoryID:":"","State":"","CustomerTypeID:":"",..........} like this.....

但JSON对象必须是：

({CreatedBy:"",EmailAddress:"[email protected]",Zipcode:"",FirstName:"devan",DeviceCategoryID::"",State:"",CustomerTypeID:"" })

我使用.NET服务器张贴。

请求不会发送到服务器。任何人都请帮助我。

输出看起来正确。请花10分钟时间学习[JSON格式]（http://www.json.org）。如果你无法在服务器端解析这个json，那么问题在于别处。 – Mar0ux 2013-05-03 11:05:46

你总是可以使用http://json.parser.online.fr/来验证你的输出。 – Mar0ux 2013-05-03 11:07:02

NSString *urlString = @"Your Web Service URL"; 

NSString *parameterString = @"XYZ"; 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
[request setURL:[NSURL URLWithString:urlString]]; 
[request setHTTPMethod:@"POST"]; 

NSMutableData *body = [NSMutableData data]; 

// parameter 
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"parameter_key\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:parameterString dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

// close form 
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 


// setting the body of the post to the reqeust 
[request setHTTPBody:body]; 

// now lets make the connection to the web 
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 

NSLog(@"returnString %@",returnString);
