后台php脚本代码

header('Content-Type:text/plain;charset=utf-8');

$json = file_get_contents('php://input');

// 反序列化JSON

$obj = json_decode($json, TRUE );

// 打印对象明细信息

print_r(json_encode($obj));

?>

iOS上的代码如下

//

// ViewController.m

// POST 通过JSON传数据

@interface ViewController ()

@property (nonatomic,strong) Person *person;

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

{

[self postJson];

}

- (void)postJson

{

NSURL *url = [NSURL URLWithString:@"http://localhost/post/postjson.php"];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:1 timeoutInterval:15];

request.HTTPMethod = @"post";

// 自定义字典

NSDictionary *dict = @{@"name":@"bbb",@"age":@(11)};

// 字典转模型

self.person = [Person personWithDict:dict];

// 模型转字典 －－－ 取其中一个键值

NSDictionary *dict1 = [self.person dictionaryWithValuesForKeys:@[@"age"]];

// 序列化

NSData *data = [NSJSONSerialization dataWithJSONObject:dict1 options:0 error:NULL];

request.HTTPBody = data;

[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

id res = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];

NSLog(@"%@",res);

}];

}

@end 测试的话可以去掉字典转模型的步骤，直接传字典进行序列化的
