我的网络层是这么设计的

1.分析

我的网络层是这么设计的

从图中我们看到:

1.每个页面的Controller负责组装para参数,调用Api类的接口方法

2.Api类在发起请求之前,追加公共参数

3.Api类序列化son数据(使用afn来完成),并且返回NSDictionary的数据,和一个NSOpration类型的请求操作的引用。

4.使用ApiPath头文件来存放接口路径

返回一个NSOpration类型的请求操作的引用是为了能在Controller里面取消请求并且释放请求。

2.实现

我的网络层是这么设计的

ApiPath.h 存放所有接口的路径,是一组宏定义

//域名 #define kDomain @"https://api.xxx.cn/" //注册 #define kRegiser [NSString                stringWithFormat:@"%@login/regis",kDomain] //登录 #define kLogin [NSString                  stringWithFormat:@"%@login/login",kDomain] ...... //以上两个接口举例子,剩下的就不多写了,没意义!

Api.h定义了项目所有的接口

#import <Foundation/Foundation.h> #import <AFNetworking.h>//引入AFN  typedef void (^ApiSuccessBlock)(NSDictionary *dic);//请求成功的回调 typedef void (^ApiFailedBlock)(void);//请求失败的回调  @interface Api : NSObject #pragma mark - 注册 + (NSOperation *)apiRegisterWithPara:(NSMutableDictionary *)parameter                              success:(ApiSuccessBlock)successBlock                               failed:(ApiFailedBlock)failedBlock; #pragma mark - 登陆 + (NSOperation *)apiLogInWithPara:(NSMutableDictionary *)parameter                          success:(ApiSuccessBlock)successBlock                           failed:(ApiFailedBlock)failedBlock; ..... @end

Api.m的实现部分

@implementation Api  //首先看一下发起请求的方法 /**  *  发起请求  *  *  @param type         请求类型  *  @param path         路径  *  @param muDict       参数  *  @param successBlock 成功回调  *  @param failedBlock  失败回调  *  *  @return 请求操作的引用  */ +(AFHTTPRequestOperation *)sendRequestWith:(NSString *)type                                       path:(NSString *)path                                 parameters:(NSMutableDictionary *)muDict                                    success:(ApiSuccessBlock)successBlock                                     failed:(ApiFailedBlock)failedBlock {     AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];     //1.设置超时时间     manager.requestSerializer.timeoutInterval = 15;          //2.添加用户信息     [self appendUserInfo:muDict];               if ([type isEqualToString:@"get"]) {         AFHTTPRequestOperation *request = [manager GET:path parameters:muDict success:^(AFHTTPRequestOperation *operation, id responseObject) {             GLLog(@"GET URL (SUCCESS) :/n%@",[operation.response.URL absoluteString]);             GLLog(@"GET URL (RESULT)  : /n%@",responseObject);             successBlock(responseObject);         } failure:^(AFHTTPRequestOperation *operation, NSError *error) {             GLLog(@"GET URL (FAILED) :/n%@",[operation.response.URL absoluteString]);             GLLog(@"GET URL (ERROR)  : /n%@",error);             failedBlock();         }];         return request;     }else{         AFHTTPRequestOperation *request = [manager POST:path parameters:muDict success:^(AFHTTPRequestOperation *operation, id responseObject) {             GLLog(@"POST URL (SUCCESS): %@ /nPARAMETER -- /n%@",path,muDict);             GLLog(@"POST URL (RESULT) : %@ /nRESULT -- /n%@",path,responseObject);                          successBlock(responseObject);         } failure:^(AFHTTPRequestOperation *operation, NSError *error) {             GLLog(@"POST URL (FAILED): %@ /nPARAMETER : /n%@",path,muDict);             GLLog(@"POST URL (FAILED): %@ /nERROR INFO:     /n%@",path,error);             failedBlock();         }];         return request;     } }  /**  *  追加用户信息  *  */ + (void)appendUserInfo:(NSMutableDictionary *)parameter{          if ([GlobalObj shareObj].account) {         [parameter setObject:[NSString stringWithFormat:@"%d",[GlobalObj shareObj].account.user_id] forKey:@"user_id"];         [parameter setObject:[GlobalObj shareObj].account.access_token forKey:@"access_token"];     } }  #pragma mark - 注册 + (NSOperation *)apiRegisterWithPara:(NSMutableDictionary *)parameter                              success:(ApiSuccessBlock)successBlock                               failed:(ApiFailedBlock)failedBlock{     return [self sendRequestWith:@"post" path:kRegiser parameters:parameter success:successBlock failed:failedBlock]; }  #pragma mark - 登陆 + (NSOperation *)apiLogInWithPara:(NSMutableDictionary *)parameter                          success:(ApiSuccessBlock)successBlock                           failed:(ApiFailedBlock)failedBlock {     return [self sendRequestWith:@"get" path:kLoginWithMobile parameters:parameter success:successBlock failed:failedBlock]; } //...... //后面的新的接口,在ApiPath中添加路径,在这后面添加方法就行了  @end 

3.使用

以注册页面为例,在Controller中使用方法如下:

/**  *  用来接收发起的请求,你可以把这个属性抽出来放到父类中,避免写多次  */ @property (nonatomic, strong) NSOperation *op;
[self.parameters setObject:self.phoneField.text forKey:@"user_name"]; [self.parameters setObject:self.pwField.text forKey:@"password"]; [self.parameters setObject:self.codeField.text forKey:@"code"]; self.op = [Api apiRegisterWithPara:self.parameters success:^(NSDictionary *dic) {    //正常    //在这里实现Model以及刷新数据     } } failed:^{     //网络错误 }]; 
//在Controller的dealloc方法面,取消并释放请求 //同样的,你也可以把他写在父类中去、 - (void)dealloc{     [self.op cancel];     self.op = nil; }
