NSURLConnection 实现webView显示HTTPS页面
我们在浏览器访问https页面的时候的,会弹出:
信任证书
我们接下来信任证书以及显示出来
遵循协议
@interface ViewController ()<NSURLConnectionDataDelegate>

interface:
@interface ViewController ()<NSURLConnectionDataDelegate>
/**
-
存储data数据
*/
@property(nonatomic,strong)NSMutableData *dataM;
/** -
访问url链接
*/
@property(nonatomic,strong)NSURL *url;
@property(nonatomic,weak)IBOutlet UIWebView *webView;
@end实现代理方法:
#pragma mark - NSURLSessionDataDelegate代理方法
-(void)URLSession:(NSURLSession )session task:(NSURLSessionTask )task
didReceiveChallenge:(NSURLAuthenticationChallenge *)challengecompletionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * __nullable credential))completionHandler
{
NSLog(@"challenge = %@",challenge.protectionSpace.serverTrust); //判断是否是信任服务器证书 if (challenge.protectionSpace.authenticationMethod ==NSURLAuthenticationMethodServerTrust) { //创建一个凭据对象 NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]; //告诉服务器客户端信任证书 [challenge.sender useCredential:credential forAuthenticationChallenge:challenge]; }
}
/** -
接收到服务器返回的数据时调用
*/
-(void)connection:(NSURLConnection )connection didReceiveData:(NSData )data
{NSLog(@"接收到的数据%zd",data.length); [self.dataM appendData:data];
}
/** -
请求完毕
*/
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{NSString *html = [[NSString alloc]initWithData:self.dataM encoding:NSUTF8StringEncoding]; NSLog(@"请求完毕"); [self.webView loadHTMLString:html baseURL:self.url];
}
懒加载:
-(NSMutableData *)dataM
{if (_dataM == nil) { _dataM = [[NSMutableData alloc]init]; } return _dataM;
}
