ios 对于AFNetworking3.0之前版本的Get、Post请求的封装(直接调用即可)

对于AFNetworking的认识我想大家都不陌生，AFNetworking在3.0版本中删除了基于 NSURLConnection API的所有支持。如果项目以前使用过这些API,那么我们需要升级到基于 NSURLSession 的API的AFNetworking的版本。

以下的是针对AFNetworking3.0之前的封装，关于AFN3.0的改变我会在稍后的博客中进行介绍，毕竟多多少少还是有些人在使用AFNetwoking3.0之前的版本。

#GetData.h

首先在.h中创建三个AFHTTPRequestOperationManager对象

#import "AFHTTPRequestOperationManager.h"

@property(nonatomic,strong)AFHTTPRequestOperationManager *requestGetManager;@property(nonatomic,strong)AFHTTPRequestOperationManager *requestPOSTManager;@property(nonatomic,strong)AFHTTPRequestOperationManager *requestHeaderPOSTManager;

同样的全局调用还是使用单例类方便一些

+ (GetData *)sharedInstance;

Get请求的方法

/**! @brief GET 请求 @param parameters 传入的参数 @param success 调用接口成功后返回一个id类型值 @param failure 调用接口失败后返回一个错误描述 @return Dictiont */- (void)GETUrl:(NSString *)url parameters:(NSDictionary *)parameters    success:(void (^)(id responseObject))success    failure:(void (^)(NSError *error))failure;

Post方法

/**! @brief POST 请求 @param parameters 传入的参数 @param success 调用接口成功后返回一个id类型值 @param failure 调用接口失败后返回一个错误描述 */- (void)POSTUrl:(NSString *)url parameters:(NSDictionary *)parameters     success:(void (^)(id responseObject))success     failure:(void (^)(NSError *error))failure;

上传头像的接口

/**! @brief POST 上存头像专用接口 @param parameters 传入的参数 @param data 上存头像的文件 @param success 调用接口成功后返回一个id类型值 @param failure 调用接口失败后返回一个错误描述 */- (void)HeaderPOSTUrl:(NSString *)url parameters:(NSDictionary *)parameters        data:(NSData *)data        keyname:(NSString *)namestr     success:(void (^)(id responseObject))success     failure:(void (^)(NSError *error))failure;

取消请求

<span style="font-size:18px;">- (void)cancelRequest;</span>

#GetData.m

对于单例类的基本实现

1、单例对象的实现

+ (Call_Interface *)sharedInstance{    static Call_Interface *_sharedInstance = nil;    static dispatch_once_t onceToken;    dispatch_once(&onceToken, ^{        _sharedInstance = [[Call_Interface alloc]init];    });    return _sharedInstance;}

对于Get请求方法的基本实现

<span style="font-size:14px;">- (void)GETUrl:(NSString *)url parameters:(NSDictionary *)parameters success:(void (^)(id))success failure:(void (^)(NSError *))failure{    if (!_requestGetManager) {        // 设置返回格式        _requestGetManager = [AFHTTPRequestOperationManager manager];        // 设置请求格式        _requestGetManager.responseSerializer = [AFJSONResponseSerializer serializer];    }    _requestGetManager.requestSerializer.timeoutInterval = 30;    NSLog(@"%@",url);    [_requestGetManager GET:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {        success(responseObject);    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        if (operation.cancelled == YES) {            return ;        }        failure(error);    }];}</span>

对于POST请求的实现

<span style="font-size:14px;">- (void)POSTUrl:(NSString *)url parameters:(NSDictionary *)parameters success:(void (^)(id))success failure:(void (^)(NSError *))failure{    if (!_requestPOSTManager) {        // 设置返回格式        _requestPOSTManager = [AFHTTPRequestOperationManager manager];        // 设置请求格式        _requestPOSTManager.responseSerializer = [AFJSONResponseSerializer serializer];    }    _requestPOSTManager.requestSerializer.timeoutInterval = 30;    NSLog(@"%@",url);    [_requestPOSTManager POST:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {        success(responseObject);    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {//        if (operation.cancelled == YES) {//            return ;//        }        failure(error);    }];    //    _mutaDiction = nil;}</span>

对于头像上传的方法实现

<span style="font-size:14px;">- (void)HeaderPOSTUrl:(NSString *)url parameters:(NSMutableDictionary *)parameters data:(NSData *)data keyname:(NSString *)namestr success:(void (^)(id))success failure:(void (^)(NSError *))failure{    if (!_requestHeaderPOSTManager) {        // 设置返回格式        _requestHeaderPOSTManager = [AFHTTPRequestOperationManager manager];        // 设置请求格式        _requestHeaderPOSTManager.responseSerializer = [AFJSONResponseSerializer serializer];    }    _requestHeaderPOSTManager.requestSerializer.timeoutInterval = 30;    NSLog(@"%@",url);    [_requestHeaderPOSTManager POST:url parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {        if (data!=nil) {            int nowdate = [[NSString stringWithFormat:@"%ld",(long)[[NSDate date] timeIntervalSince1970]] intValue];            NSString * fileName = [NSString stringWithFormat:@"%d.jpg",nowdate];            [formData appendPartWithFileData:data name:namestr fileName:fileName mimeType:@"image/jpeg"];        }    } success:^(AFHTTPRequestOperation *operation, id responseObject) {        success(responseObject);    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        if (operation.cancelled == YES) {            return ;        }        failure(error);    }];    }</span>

取消请求

- (void)cancelRequest{    if (_requestGetManager) {        [_requestGetManager.operationQueue cancelAllOperations];        _requestGetManager = nil;    }    if (_requestHeaderPOSTManager) {        [_requestHeaderPOSTManager.operationQueue cancelAllOperations];        _requestHeaderPOSTManager = nil;    }    if (_requestPOSTManager) {        [_requestPOSTManager.operationQueue cancelAllOperations];        _requestPOSTManager = nil;    }}

最后别忘了释放内存

- (void)dealloc{    _requestGetManager = nil;    _requestPOSTManager = nil;    _requestHeaderPOSTManager = nil;}
