我的IOS代码是
let reposURL = NSURL(string: "http://localhost/Test/test.html")
// 2
do{
if let JSONData = NSData(contentsOfURL: reposURL!) {
// 3
if let json = try NSJSONSerialization.JSONObjectWithData(JSONData, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary {
// 4
if let reposArray = json["items"] as? [NSDictionary] {
// 5
for item in reposArray {
// if let name = item.valueForKey("name") {
// NameOfArtist.append(name as! String)
//}
}
}
}
}
}catch{}
我的 Json Outout 是

我用另一个 Web 服务链接测试了这段代码
"https://api.github.com/search/repositories?q=learn+swift+language:swift&sort=stars&order=desc"
..然后它起作用了。我的代码或 json 文件有什么问题吗
您必须遵循此操作才能调用任何 Web 服务
有关完整的详细信息,请参阅Apple的Info.plist参考(感谢@gnasher729)。
您可以在 Info.plist 中为特定域添加例外:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>testdomain.com</key>
<dict>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSExceptionRequiresForwardSecrecy</key>
<true/>
<key>NSExceptionMinimumTLSVersion</key>
<string>TLSv1.2</string>
<key>NSThirdPartyExceptionAllowsInsecureHTTPLoads</key>
<false/>
<key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
<true/>
<key>NSThirdPartyExceptionMinimumTLSVersion</key>
<string>TLSv1.2</string>
<key>NSRequiresCertificateTransparency</key>
<false/>
</dict>
</dict>
</dict>
每个例外域的所有密钥都是可选的。演讲者没有详细说明任何键,但我认为它们都相当明显。
(来源:WWDC 2015 会议 703,"隐私和您的应用程序",30:18)
如果你的应用有充分的理由,还可以使用单个密钥忽略所有应用传输安全限制:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
如果您的应用没有充分的理由,您可能会面临被拒绝的风险:
将 NSAllowsArbitraryLoads 设置为 true 将允许它工作,但是 苹果非常明确,他们打算拒绝使用它的应用程序 没有特定原因的标志。使用的主要原因 NSAllowsArbitraryLoad我能想到的是用户创建的内容 (链接共享、自定义网络浏览器等)。在这种情况下,苹果仍然 希望您包含对 URL 强制执行 ATS 的例外 一切由您掌控。
如果确实需要访问未通过 TLS 1.2 提供的特定 URL,则需要为这些域编写特定的例外,而不是使用 NSAllowsArbitraryLoads 设置为 yes。您可以在 NSURLSesssion WWDC 会话中找到更多信息。
在共享 NSAllowsArbitraryLoads 解决方案时请小心。这不是苹果推荐的修复程序。- Kcharwood(感谢@marco-Tolman)
Web 服务应返回其响应,并将标头Content-Type
设置为 application/json
,以便NSJSONSerialization.JSONObjectWithData()
正常工作。
