iOS开发-AFNetworking网络请求及上传下载功能

AFNetworking是一个轻量级的iOS网络通信类库，可以方便实现网络请求。

一、使用AFNetworking

在Podfile中安装

pod 'AFNetworking'

  • 1

导入AFNetworking

#import "AFNetworking.h"

  • 1

AFNetworking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"]];

    HttpClientTypeWithOut,      //mob提供的天气等服务
} ;

typedef NS_ENUM(NSInteger, UploadMimeType) {
    UploadMimeTypeDefault,  //默认
    UploadMimeTypeImage,    //图片
    UploadMimeTypeAudio,    //音频
    UploadMimeTypeVideo,    //视频
} ;


typedef NS_ENUM(NSInteger, HttpErrorType) {
    HttpErrorTypeDefault = 0,   //默认
    HttpErrorTypeNetWork,       //网络出错
    HttpErrorTypeTimeout,       //请求超时
