SocketRocket和固定证书错误？

Question

我正在使用SocketRocket，到目前为止一切都很好，今天我想试着锁定一个(自签名的)证书，但我得到了一个错误：

- (void)connectWebSocket {
    webSocket.delegate = nil;
    webSocket = nil;

    NSString *urlString = [NSString stringWithFormat: @"wss://%@:%@", server_ip, server_port];

    //NSLog(@"%@", urlString);

    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]
                                             cachePolicy: NSURLRequestUseProtocolCachePolicy
                                         timeoutInterval:5.0];


    // pin down certificate
    NSString *cerPath = [[NSBundle mainBundle] pathForResource:@"myOwnCertificate" ofType:@"cer"];
    NSData *certData = [[NSData alloc] initWithContentsOfFile:cerPath];
    CFDataRef certDataRef = (__bridge CFDataRef)certData;
    SecCertificateRef certRef = SecCertificateCreateWithData(NULL, certDataRef);
    id certificate = (__bridge id)certRef;
    [request setSR_SSLPinnedCertificates:@[certificate]];

    SRWebSocket *newWebSocket = [[SRWebSocket alloc] initWithURLRequest: request];
    newWebSocket.delegate = self;

    [newWebSocket open];

    socketIsOpen = true;

}

错误：'NSURLRequest‘没有可见的@接口声明了选择器'setSR_SSLPinnedCertificates:’

我是不是遗漏了什么？

谢谢!

Answer 1

你需要#import "SRWebSocket.h"。

SR_SSLPinnedCertificates是https://github.com/square/SocketRocket/blob/master/SocketRocket/SRWebSocket.h中NSURLRequest (CertificateAdditions)类别的属性

Answer 2

request需要是NSMutableURLRequest类型。当你的request是NSURLRequest类型时，SR_SSLPinnedCertificates是只读的，所以你可以不设置它。

#pragma mark - NSURLRequest (CertificateAdditions)

@interface NSURLRequest (CertificateAdditions)

@property (nonatomic, retain, readonly) NSArray *SR_SSLPinnedCertificates;

@end

#pragma mark - NSMutableURLRequest (CertificateAdditions)

@interface NSMutableURLRequest (CertificateAdditions)

@property (nonatomic, retain) NSArray *SR_SSLPinnedCertificates;

@end

将您的代码更改为：

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]
                                             cachePolicy: NSURLRequestUseProtocolCachePolicy
                                         timeoutInterval:5.0];

这应该是可行的:)
