#import AFNetworking.hAFNetworking下载地址https://github.com/AFNetworking/AFNetworking
二、AFHTTPSessionManager
AFHTTPSessionManager提供了各种请求方式并支持https格式。
AFHTTPSessionManager可以允许使用无效的SSL证书
AFHTTPSessionManager *manager [AFHTTPSessionManager manager];
manager.securityPolicy.allowInvalidCertificates YES; // 不建议用于生产环境三、实现常用的请求封装设置
配置请求超时时间、Content-Type、acceptableContentTypes
_httpManager [[AFHTTPSessionManager alloc] init];_httpManager.operationQueue.maxConcurrentOperationCount 6;_httpManager.requestSerializer [AFJSONRequestSerializer serializer];[_httpManager.requestSerializer willChangeValueForKey:timeoutInterval];[_httpManager.requestSerializer setTimeoutInterval:10];[_httpManager.requestSerializer setStringEncoding:NSUTF8StringEncoding];_httpManager.responseSerializer [AFJSONResponseSerializer serializer];// [_manager.requestSerializer setValue:multipart/form-data forHTTPHeaderField:Content-Type];[_httpManager.requestSerializer setValue:application/x-www-form-urlencoded forHTTPHeaderField:Content-Type];_httpManager.responseSerializer.acceptableContentTypes [NSSet setWithObjects:text/plain, multipart/form-data, application/json, text/html, image/jpeg, image/png, application/octet-stream, text/json, text/javascript, text/html, nil];_httpManager.requestSerializer.HTTPMethodsEncodingParametersInURI [NSSet setWithArray:[POST, GET, HEAD, PUT, DELETE]];完整代码如下
