在 Web 服务上传递数组

Question

我正在开发一个应用程序，因为我曾经通过 WebServices 将我的联系号码发送到服务器。这里我获取我的联系号码一个数组，然后我通过 webservices 发送联系人数组。下面的代码，

NSString *myRequestString1 = [[NSString alloc] initWithFormat:@"contact_numbers=%@",MobiileArray ];


NSData *myRequestData = [ NSData dataWithBytes: [ myRequestString1 UTF8String ] length: [ myRequestString1 length ] ];
NSMutableURLRequest *request = [ [ NSMutableURLRequest alloc ] initWithURL: [ NSURL URLWithString:@"http://myproject.in/myproject-contacts.php"]];

[request setHTTPMethod: @"POST"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
[request setHTTPBody: myRequestData];
NSURLResponse *response;
NSError *err;
NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse:&response error:&err];
NSError* error;
NSMutableArray* result = [NSJSONSerialization JSONObjectWithData:returnData
                                                         options:kNilOptions

                                                           error:&error];
NSLog(@"result: %@", result);

但响应为空，我的代码有错误吗？可以给我推荐一下吗谢谢。

试试下面的解决方案..！

替换这行代码

NSString *myRequestString1 = [[NSString alloc] initWithFormat:@"contact_numbers=%@",MobiileArray ];
NSData *myRequestData = [ NSData dataWithBytes: [ myRequestString1 UTF8String ] length: [ myRequestString1 length ] ];

//有了这行代码

//NSDictionary *dict = [NSDictionary dictionaryWithObject: MobiileArray forKey:@"contact_numbers"];

NSString* myRequestString1 = [MobiileArray JSONRepresentation];
NSData *myRequestData = [myRequestString1 dataUsingEncoding:NSUTF8StringEncoding];

//放

[request setValue:@"application/json" forHTTPHeaderField:@"content-type"];

检查一下...
