1、最近做项目、文件存储服务器是用的亚马逊的、如果直接访问、下载其资源速度很慢、所以需要在网络请求的时候添加一个代理、加速网络访问
2、代理服务器是一个HTTPS 的一个服务器
3、思路、解决方案、利用运行时机制(添加分类NSURLSession+Change)针对 NSURLSession 初始化添加代理对所有的网络请求进行拦截处理
#import "NSURLSession+Change.h" @implementation NSURLSession (Change) +(void)load{ Method oldMethod = class_getClassMethod(self, @selector(sessionWithConfiguration:delegate:delegateQueue:)); Method newMethod = class_getClassMethod(self, @selector(newSessionWithConfiguration:delegate:NSURLSessiondelegateQueue:)); Method oldMethod1 = class_getClassMethod(self, @selector(sessionWithConfiguration:)); Method newMethod1 = class_getClassMethod(self, @selector(newSessionWithConfiguration:)); method_exchangeImplementations(oldMethod1, newMethod1); method_exchangeImplementations(oldMethod, newMethod); } + (NSURLSession *)newSessionWithConfiguration:(NSURLSessionConfiguration *)configuration{ configuration=[self newConfiguration:configuration]; NSURLSession *section= [self newSessionWithConfiguration:configuration]; return section; } + (NSURLSession *)newSessionWithConfiguration:(NSURLSessionConfiguration *)configuration delegate:(nullable id <NSURLSessionDelegate>)delegate NSURLSessiondelegateQueue:(nullable NSOperationQueue *)queue{ configuration=[self newConfiguration:configuration]; NSURLSession *section= [self newSessionWithConfiguration:configuration delegate:delegate NSURLSessiondelegateQueue:queue]; return section; } #pragma mark 添加代理,加速网络请求 +(NSURLSessionConfiguration *)newConfiguration:(NSURLSessionConfiguration *)configuration{ //通过服务器配置HTTPS代理 NSString *proxy=@""; NSInteger port=; configuration.connectionProxyDictionary = @{ @"HTTPEnable":@YES, @"HTTPProxy":proxy, @"HTTPPort":@(port), @"HTTPSEnable":@YES, @"HTTPSProxy":proxy, @"HTTPSPort":@(port), }; NSString *user=@""; NSString *password=@""; NSString* proxyIDPasswd = [NSString stringWithFormat:@"%@:%@",user,password]; NSData* proxyoriginData = [proxyIDPasswd dataUsingEncoding:NSUTF8StringEncoding]; NSString *base64EncodedCredential = [proxyoriginData base64EncodedStringWithOptions:0]; NSString *authString = [NSString stringWithFormat:@"Basic: %@", base64EncodedCredential]; configuration.HTTPAdditionalHeaders = @{@"Proxy-Authorization": authString}; return configuration; } @end
