post發(fā)送JSON數(shù)據(jù)給服務(wù)器

觸發(fā)發(fā)送的方法

• 這次Demo是通過點(diǎn)擊屏幕觸發(fā)發(fā)送數(shù)據(jù)給服務(wù)器事件
• 前提需要開啟本地模擬服務(wù)器

-  (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{

    NSURL *url = [NSURL URLWithString:@"http://127.0.0.1/post/postjson.php"];
    
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:15];
    
    request.HTTPMethod = @"POST";
    
    //選擇不同類型的data發(fā)送給服務(wù)器
//    request.HTTPBody = [self jsonString];

//    request.HTTPBody = [self dictionaryData];

//    request.HTTPBody = [self arrayData];
    
    request.HTTPBody = [self objectData];
    
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
    [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {
        
        if (data == nil || connectionError != nil) {
            NSLog(@"請求數(shù)據(jù)失斃湮尽漱挎！");
            return ;
        }
        
//        id recive = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];
//服務(wù)器返回的時(shí)字符串
        NSString *recive = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
        
        NSLog(@"%@", recive);
     
    }];
#pragma clang diagnostic pop
}

發(fā)送JSON字符串

- (NSData *)jsonString{

NSString *string = @"{\"name\":\"zhangsan\",\"age\":\"18\"}";

NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding];

return data;
}

發(fā)送字典給服務(wù)器

- (NSData *)dictionaryData{

NSDictionary *dict = @{
                       @"name":@"zhangsan",
                       @"age":@18
                       
                       };
//通過序列化成data類型
NSData *data = [NSJSONSerialization dataWithJSONObject:dict options:0 error:NULL];

return data;
}

發(fā)送數(shù)組給服務(wù)器

- (NSData *)arrayData{

NSArray *array = @[
                   @{@"zhangsan":@18},
                   @{@"lisi":@20}
                   ];
NSData *data =[NSJSONSerialization dataWithJSONObject:array options:0 error:NULL];

return data;
}

發(fā)送oc對象給服務(wù)器

• 先將對象轉(zhuǎn)換為字典
• 通過系統(tǒng)提供的JSON解析類進(jìn)行序列化

    - (NSData *)objectData{

    RZPerson *person = [[RZPerson alloc]init];
    
    person.name = @"zhangsan";
    
    person.age = 20;
    
    //先將對象轉(zhuǎn)換為字典類型
    NSDictionary *dict = [person dictionaryWithValuesForKeys:@[@"name",@"age"]];
    
    //將字典轉(zhuǎn)換為data類型
    NSData *data = [NSJSONSerialization dataWithJSONObject:dict options:0 error:NULL];

    return data;
    }
