【问题描述】：

我正在使用 SocketRocket，到目前为止一切正常，今天我想尝试确定一个（自签名）证书，但出现错误：

- (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@interface 声明选择器“setSR_SSLPinnedCertificates:”

我错过了什么吗？

谢谢！

【解决方案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

【解决方案2】：

request 必须是 NSMutableURLRequest 类型。当您的request 是NSURLRequest 类型时，SR_SSLPinnedCertificates 是只读，因此您可以不设置它。

#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];

这应该可行:)
