  • HTTPS请求处理

    HTTPS请求的时候:

    [1]证书是受信任的,什么都不用做

    [2]证书是不受信任的,是自签名的

      (1)修改配置文件,禁用ATS特性

      (2)信任并安装数字证书

    NSURLSession的示例代码如下:

    #import "ViewController.h"
    
    @interface ViewController ()<NSURLSessionDataDelegate>
    
    @end
    
    @implementation ViewController
    
    - (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
        NSURL *url = [NSURL URLWithString:@"https://kyfw.12306.cn/otn/"];
        NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:self delegateQueue:[NSOperationQueue mainQueue]];
        [[session dataTaskWithURL:url completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
            NSLog(@"%@", [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
        }] resume];
    }
    
    
    - (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable))completionHandler {
        NSLog(@"%@", challenge.protectionSpace);
        /*
        NSURLSessionAuthChallengeUseCredential = 0,            Use the specified credential, which may be nil
        NSURLSessionAuthChallengePerformDefaultHandling = 1,   Default handling for the challenge - as if this delegate were not implemented; the credential parameter is ignored.
        NSURLSessionAuthChallengeCancelAuthenticationChallenge = 2, The entire request will be canceled; the credential parameter is ignored.
        NSURLSessionAuthChallengeRejectProtectionSpace = 3,         This challenge is rejected and the next authentication protection space should be tried; the credential parameter is ignored.
        */
        NSURLCredential *credentail = [[NSURLCredential alloc] initWithTrust:challenge.protectionSpace.serverTrust];
        completionHandler(NSURLSessionAuthChallengeUseCredential, credentail);
    }
