封装网络框架的必要性

• 在应用程序开发中，一定要封装隔离网络框架

• 示意图如下：

OC 封装网络工具

• 新建网络工具类 NetworkTools

• 实现单例

+ (instancetype)sharedTools {    static NetworkTools *instance;    static dispatch_once_t onceToken;    dispatch_once(&onceToken, ^{instance = [[NetworkTools alloc] initWithBaseURL:nil];instance.responseSerializer.acceptableContentTypes = [instance.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];});    return instance;
}

• 建立网络请求方法

- (void)request:(NSString *)URLString parameters:(id)parameters finished:(void (^)(id result, NSError *error))finished {NSAssert(finished != nil, @"必须输入完成回调");[self GET:URLString parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject) {finished(responseObject, nil);} failure:^(NSURLSessionDataTask * _Nonnull task, NSError * _Nonnull error) {finished(nil, error);}];
}

• 测试网络请求

[[NetworkTools sharedTools] request:@"http://www.weather.com.cn/data/sk/101010100.html" parameters:nil finished:^(id result, NSError *error) {    NSLog(@"%@ %@", result, error);
}];

• 定义 HTTP 请求枚举类型

/// HTTP 请求方法枚举typedef enum : NSUInteger {    GET,    POST,
} HTTPRequestMethod;

• 从 AFHTTPSessionManager.m 中复制 dataTaskWithHTTPMethod 函数定义

@protocol NetworkToolsProxy <NSObject>@optional- (NSURLSessionDataTask *)dataTaskWithHTTPMethod:(NSString *)methodURLString:(NSString *)URLStringparameters:(id)parameterssuccess:(void (^)(NSURLSessionDataTask *, id))successfailure:(void (^)(NSURLSessionDataTask *, NSError *))failure;@end

• 修改 request 方法

- (void)request:(HTTPRequestMethod)method URLString:(NSString *)URLString parameters:(id)parameters finished:(void (^)(id result, NSError *error))finished {NSAssert(finished != nil, @"必须输入完成回调");    NSString *methodName = (method == GET) ? @"GET" : @"POST";[[self dataTaskWithHTTPMethod:methodName URLString:URLString parameters:parameters success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject) {finished(responseObject, nil);} failure:^(NSURLSessionDataTask * _Nonnull task, NSError * _Nonnull error) {finished(nil, error);}] resume];
}

• 测试 GET 请求

[[NetworkTools sharedTools] request:GET URLString:@"http://www.weather.com.cn/data/sk/101010100.html" parameters:nil finished:^(id result, NSError *error) {    NSLog(@"%@ %@", result, error);
}];

• 测试 POST 请求

[[NetworkTools sharedTools] request:POST URLString:@"http://httpbin.org/post" parameters:@{@"name": @"zhangsan", @"age": @18} finished:^(id result, NSError *error) {    NSLog(@"%@ %@", result, error);
}];

Swift 封装网络工具

enum HTTPRequestMethod: String {    case GET = "GET"case POST = "POST"}class NetworkTools: AFHTTPSessionManager {    // 单例static let sharedTools: NetworkTools = {        let instance = NetworkTools(baseURL: nil)instance.responseSerializer.acceptableContentTypes?.insert("text/html")        return instance}()    // 网络请求方法func request(method: HTTPRequestMethod, URLString: String, parameters: AnyObject?, finished: (result: AnyObject?, error: NSError?)->()) {        let success = { (task: NSURLSessionDataTask, result: AnyObject) -> Void infinished(result: result, error: nil)}        let failure = { (task: NSURLSessionDataTask, error: NSError) -> Void inprint(error)finished(result: nil, error: error)}        if method == .GET {            GET(URLString, parameters: parameters, success: success, failure: failure)} else {            POST(URLString, parameters: parameters, success: success, failure: failure)}}
}
