ios - 此服务器的证书对于 swift 3 上的自签名证书无效
<p><p>我正在使用 swift 3 并第一次使用 Web 服务。我的 Web 服务通过 HTTPS 运行，我想使用适当的加密进行测试。</p>
<p>到目前为止，这是我的代码:</p>
<pre><code> let config = URLSessionConfiguration.default // Session Configuration
let session = URLSession(configuration: config) // Load configuration into Session
let url = URL(string: webService.getLoginUrl())!
let task = session.dataTask(with: url, completionHandler: {
(data, response, error) in
if error == nil {
do {
if let json =
try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? {
//Implement your logic
print(json)
}
} catch {
print("error in JSONSerialization")
}
} else {
print(error!.localizedDescription)
}
})
task.resume()
</code></pre>
<p>当我对自签名的测试服务器运行此程序时，我得到:</p>
<pre><code>The certificate for this server is invalid. You might be connecting to a server that is pretending to be “10.0.0.51” which could put your confidential information at risk.
</code></pre>
<p>所以我想做的是在测试时接受所有证书，而不是在生产中。</p>
<p>我找到了几个网站，例如:</p>
<p> <a href="http://www.byteblocks.com/Post/Use-self-signed-SSL-certificate-in-iOS-application" rel="noreferrer noopener nofollow">http://www.byteblocks.com/Post/Use-self-signed-SSL-certificate-in-iOS-application</a>
<a href="https://github.com/socketio/socket.io-client-swift/issues/326" rel="noreferrer noopener nofollow">https://github.com/socketio/socket.io-client-swift/issues/326</a> </p>
<p>但这些似乎早于 swift 3。</p>
<p>我该如何解决这个问题？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>经过大量研究，我了解了代理如何在 swift 3 中使用 URLSession 对象。发布链接的部分太多，但最后，这是最有帮助的:<a href="https://gist.github.com/stinger/420107a71a02995c312036eb7919e9f9" rel="noreferrer noopener nofollow">https://gist.github.com/stinger/420107a71a02995c312036eb7919e9f9</a> </p>
<p>所以，为了解决这个问题，我从 URLSessionDelegate 继承了我的类，然后添加了以下函数:</p>
<pre><code>func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
//accept all certs when testing, perform default handling otherwise
if webService.isTesting() {
print("Accepting cert as always")
completionHandler(.useCredential, URLCredential(trust: challenge.protectionSpace.serverTrust!))
}
else {
print("Using default handling")
completionHandler(.performDefaultHandling, URLCredential(trust: challenge.protectionSpace.serverTrust!))
}
}
</code></pre>
<p>isTesting() 调用确定我是否正在使用测试服务器，然后如果我们处于测试模式，我们将接受所有证书。</p></p>
