[Swift]Xcode模拟器无法请求http接口问题

news 来源：原创 2025/8/10 22:56:34

1.以前偷懒一直是这样设置

<key>NSAppTransportSecurity</key>
<dict><key>NSAllowsArbitraryLoads</key><true/>
</dict>

现在我在Xcode16.3上，这种设置方式在真机上能请求http（应该是设备开启了开发者模式），但在模拟器上请求http是被拒绝的。报错如下：

Cannot start load of Task <AAC1C590-5604-43A7-984F-3D486C5996DF>.<1> since it does not conform to ATS policy

Task <AAC1C590-5604-43A7-984F-3D486C5996DF>.<1> finished with error [-1022] Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSLocalizedDescription=The resource could not be loaded because the App Transport Security policy requires the use of a secure connection., NSErrorFailingURLStringKey=http://114.55.151.190:9527/api/onlineGoods/getGoodsList?page=1&pageSize=20, NSErrorFailingURLKey=http://114.55.151.190:9527/api/onlineGoods/getGoodsList?page=1&pageSize=20, _NSURLErrorRelatedURLSessionTaskErrorKey=(
"LocalDataTask <AAC1C590-5604-43A7-984F-3D486C5996DF>.<1>"
), _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <AAC1C590-5604-43A7-984F-3D486C5996DF>.<1>, NSUnderlyingError=0x60000129bde0 {Error Domain=kCFErrorDomainCFNetwork Code=-1022 "(null)"}}

问题就是由于 App Transport Security (ATS) 默认限制了非 HTTPS 请求。

2.现在需要这样设置

<key>NSAppTransportSecurity</key>
<dict><key>NSAllowsArbitraryLoads</key> <false/><key>NSExceptionDomains</key><dict><key>example.com</key> <!--Include your domain at this line --><dict><key>NSIncludesSubdomains</key><true/><key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key><true/><key>NSTemporaryExceptionMinimumTLSVersion</key><string>TLSv1.1</string></dict></dict>
</dict>

这里NSAllowsArbitraryLoads必须是false，因为它不允许所有不安全的连接，但例外列表允许连接到一些没有 HTTPS 的域。

这样模拟器上就能正常请求http接口了。
