AFNetworking请求

1.get请求
+(void)getHttpRequestWithURLStr:(NSString *)urlStr withResponseBlock:(void(^)(id sender))completion{

AFHTTPRequestOperationManager *manager =[AFHTTPRequestOperationManager manager];

manager.requestSerializer = [AFHTTPRequestSerializer serializer];


//以下设置也可行
//manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"application/x-json",@"text/html", nil];

manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObjectsFromSet:[NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"application/x-json",@"text/html", nil]];


manager.requestSerializer.timeoutInterval = 10;

[manager.requestSerializer setValue:@"6d4dd17ce6800b2ec941627ca1137378" forHTTPHeaderField:@"apikey"];
//post如果需要传参数
//NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:@"对应的值值",@"对应的key", nil];
//NSDictionary *params = @{@"key" : @"value",
//                         @"key" : @"value",
//                         @"key" : @"value"};


NSDictionary *params = nil;
//发送请求
[manager GET:urlStr parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject){
    
    NSLog(@"GET请求成功");
    completion(responseObject);
    
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"error:%@",error);
    NSLog(@"GET请求失败");

}];

}
2.post请求参数传数组
+(void)postHttpRequestWithURLStr:(NSString *)urlStr withParametersArray:(NSArray *)parameters withResponseBlock:(void(^)(id sender))completion{

AFHTTPSessionManager *session = [AFHTTPSessionManager manager];

session.responseSerializer = [AFHTTPResponseSerializer serializer];

session.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

session.requestSerializer = [AFJSONRequestSerializer serializer];

session.responseSerializer = [AFJSONResponseSerializer serializer];

[session.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];

[session.requestSerializer setValue:@"application/json;charset=utf-8" forHTTPHeaderField:@"Content-Type"];


[session POST:urlStr parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject)
 {
     NSLog(@"POST请求成功");
     
     completion(responseObject);
     
 } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
     NSLog(@"POST请求失败");
 }];

}
3.post请求参数传字典
+(void)postHttpRequestWithURLStr:(NSString *)urlStr withParametersDic:(NSDictionary *)parameters withResponseBlock:(void(^)(id sender))completion
{

AFHTTPSessionManager *session = [AFHTTPSessionManager manager];

session.responseSerializer = [AFHTTPResponseSerializer serializer];

session.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

session.requestSerializer = [AFJSONRequestSerializer serializer];

session.responseSerializer = [AFJSONResponseSerializer serializer];

[session.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];

[session.requestSerializer setValue:@"application/json;charset=utf-8" forHTTPHeaderField:@"Content-Type"];

// 参数1: url
// 参数2: body体
[session POST:urlStr parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject)
 {
     NSLog(@"POST请求成功");
     
     completion(responseObject);
     
 } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
     NSLog(@"POST请求失败");
 }];

}
总结：调用测试百度天气api
//测试

NSString *httpUrl = @"http://apis.baidu.com/heweather/pro/weather";

NSString *httpArg = @"city=beijing";

NSString *urlStr = [[NSString alloc]initWithFormat: @"%@?%@", httpUrl, httpArg];

[AFManager getHttpRequestWithURLStr:urlStr withResponseBlock:^(id sender) {

    NSDictionary *dic = (NSDictionary *)sender;
    
    if (sender)
    {
       
        NSLog(@"get==========有数据%@",dic);

    }
    else
    {
        
        NSLog(@"get==========有数据");

    }
}];
