ios基于AFN封装网络请求工具

新建一个类

在.h文件中，提供网络相关的常用方法

GET请求

+(void)get:(NSString *)url params:(NSDictionary *)params success:(void (^)(id JSON))success failure:(void (^)(NSError *error))failure;

POST请求

+(void)post:(NSString *)url params:(NSDictionary *)params success:(void (^)(id JSON))success failure:(void (^)(NSError *error))failure;

PUT请求

+(void)put:(NSString *)url params:(NSDictionary *)params success:(void (^)(id JSON))success failure:(void (^)(NSError *error))failure;

网络状态监测

+(void)getDeviceNetWorkStates;
//+(UIAlertController *)showNetWorkStatusTipMesg:(NSString *)title ;

处理参数得到请求URL

+(NSString *)getURLwithParams:(NSString *)url secret:(NSString *)secret params:(NSMutableDictionary *)params;

在.m文件中实现方法

• GET

+ (void)get:(NSString *)url params:(NSDictionary *)params success:(void (^)(id))success failure:(void (^)(NSError *))failure
{  
    AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
    [policy setAllowInvalidCertificates:YES];    //如果是需要验证自建证书，需要设置为YES
    
    policy.validatesDomainName = NO;//不验证证书的域名
    
    // 1.获得请求管理者
    AFHTTPSessionManager * mgr = [AFHTTPSessionManager manager];
    mgr.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/css",@"text/plain", nil];
    
    mgr.requestSerializer.timeoutInterval = timeout;
   // mgr.operationQueue.maxConcurrentOperationCount = MaxOperationCountQueue;
    
    // 2.发送GET请求
    [mgr setSecurityPolicy:policy];
    mgr.requestSerializer = [AFHTTPRequestSerializer serializer];
    mgr.responseSerializer = [AFHTTPResponseSerializer serializer];
    
    //添加  请求头
    [mgr.requestSerializer setValue:@"abcd" forHTTPHeaderField:@"name"];
    
    [mgr GET:url parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject)
    {
        NSData *data = responseObject;
        id JSON =  [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
        if (success) {
            success(JSON);
        }
        
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if (failure) {
            failure(error);
        }
    }];  
}

• POST

+ (void)post:(NSString *)url params:(NSDictionary *)params success:(void (^)(id))success failure:(void (^)(NSError *))failure
{
    AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
    [policy setAllowInvalidCertificates:YES];
    // 1.获得请求管理者
    AFHTTPSessionManager *mgr = [AFHTTPSessionManager manager];
    mgr.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/css",@"text/plain", nil];
    
    mgr.requestSerializer.timeoutInterval = timeout;
   // mgr.operationQueue.maxConcurrentOperationCount = MaxOperationCountQueue;
    
    [mgr setSecurityPolicy:policy];
    mgr.requestSerializer = [AFHTTPRequestSerializer serializer];
    mgr.responseSerializer = [AFHTTPResponseSerializer serializer];
    
    //添加  请求头
    [mgr.requestSerializer setValue:@"abcd" forHTTPHeaderField:@"name"];
    
    // 2.发送POST请求
    [mgr POST:url parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSData *data = responseObject;
        
        id JSON =  [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
        if (success) {
            success(JSON);
        }
        
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if (failure) {
            failure(error);
        }
    }];
}

• PUT

+(void)put:(NSString *)url params:(NSDictionary *)params success:(void (^)(id))success failure:(void (^)(NSError *))failure{
    AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
    [policy setAllowInvalidCertificates:YES];
    // 1.获得请求管理者
    AFHTTPSessionManager *mgr = [AFHTTPSessionManager manager];
    mgr.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html",@"text/css",@"text/plain", nil];
    
    mgr.requestSerializer.timeoutInterval = timeout;
    // mgr.operationQueue.maxConcurrentOperationCount = MaxOperationCountQueue;
    
    [mgr setSecurityPolicy:policy];
    mgr.requestSerializer = [AFHTTPRequestSerializer serializer];
    mgr.responseSerializer = [AFHTTPResponseSerializer serializer];
    
    [mgr PUT:url parameters:params success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        if (success) {
            success(responseObject);
        }
    }failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if (failure) {
            failure(error);
        }
    }];
}

• 同步请求

+ (void)setAppleEnv{
    BOOL __block reqProcessed = NO;
    
    NSString *URLString = @"http://......."
    
    NSURLSession *session = [NSURLSession sharedSession];
    
    [[session dataTaskWithURL:[NSURL URLWithString:URLString]
            completionHandler:^(NSData *data,
                                NSURLResponse *response,
                                NSError *error) {
                //接收
                PDMessage *message = [PDMessage mj_objectWithKeyValues:data];
                
                if (message.code == 0) {
                    NSLog(@"----0 shenhe code=0");
                    
                }else if ( message.code  == 1){
                    NSLog(@"----0 product code=1");
                }
                
                reqProcessed = true;
                
            }] resume];
    
    while (!reqProcessed) {
        [NSThread sleepForTimeInterval:0];
    }
}

• 参数排序，拼接，加密，获得URL

+(NSString *)getURLwithParams:(NSString *)url secret:(NSString *)secret params:(NSMutableDictionary *)params{
    //排序
    NSArray * sortedKeys = [[params allKeys] sortedArrayUsingSelector: @selector(caseInsensitiveCompare:)];
    NSMutableString *sparam = [[NSMutableString alloc] init];
    for (int i = 0; i < sortedKeys.count; i++) {
        NSString *key = [sortedKeys objectAtIndex:i];
        NSString *value = [params objectForKey:key];
        if (i == 0) {
            [sparam appendFormat:@"%@=%@",key,value];
        }else{
            [sparam appendFormat:@"&%@=%@",key,value];
        }
    }
    if(secret != nil){
        //--加密工具方法
        PDEncryptionTools *enCoder = [[PDEncryptionTools alloc] init];
        NSString *sign = [enCoder getEncryption:sparam secret:secret];
        params[@"sign"] = sign; 
        //拼接
        [sparam appendFormat:@"&sign=%@",sign];
    }
    //请求地址
    NSString *requestURL = [NSString stringWithFormat:@"%@?%@",url,sparam];

    return requestURL;
}

• 网络状态监测
  使用通知发布状态信息

+(void)getDeviceNetWorkStates{
    AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];
    [manager startMonitoring];
    
    [manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
        
        switch (status) {
            case AFNetworkReachabilityStatusReachableViaWWAN:
                [[NSNotificationCenter defaultCenter] postNotificationName:@"netWorkState" object:nil userInfo:@{@"state":[NSString stringWithFormat:@"%zd",1]}];
                break;
            case AFNetworkReachabilityStatusReachableViaWiFi:
                [[NSNotificationCenter defaultCenter] postNotificationName:@"netWorkState" object:nil userInfo:@{@"state":[NSString stringWithFormat:@"%zd",1]}];
                break;
            case AFNetworkReachabilityStatusNotReachable:
                [[NSNotificationCenter defaultCenter] postNotificationName:@"netWorkState" object:nil userInfo:@{@"state":[NSString stringWithFormat:@"%zd",0]}];
                break;
            case AFNetworkReachabilityStatusUnknown:
                [[NSNotificationCenter defaultCenter] postNotificationName:@"netWorkState" object:nil userInfo:@{@"state":[NSString stringWithFormat:@"%zd",-1]}];
                break;
                
            default:
                break;
        }
    }];
}
