blocks|key|2761413|text|如果需要响应代码，请不要使用DataPublisher擦除.value()。相反，使用从各种DataResponse方法获得的publish，这些方法包含所有不同的响应信息，包括状态代码。然后，您可以将其.map到您需要的任何类型。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2761414|entityMap^0|E|D|T|8|1A|C|1R|7|2U|4|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|G|$]]

If you want the response code, don't erase the <code>DataPublisher</code> using <code>.value()</code>. Instead, use the <code>DataResponse</code> you get from the various <code>publish</code> methods, which includes all of the various response information, including status code. You can then <code>.map</code> it into whatever type you need.

For Swift 5.X and Xcode 12.4
For debugging purposes you can intercept the response right before the Combine publisher (publishDecodable()) and get some of the elements of the URL Response, with :
<pre><code>session.request(signedRequest)
 .responseJSON { response in
 print(response.request) // original URL request
 print(response.response) // URL response
 print(response.data) // server data
 print(response.result) // result of response serialization
 }
</code></pre>

The easy MVVM way:
<pre><code>func fetchChats() -&gt; AnyPublisher&lt;ChatListModel, AFError&gt; {
 let url = URL(string: &quot;Your_URL&quot;)!
 AF.request(url, method: .get)
 .validate()
 .publishDecodable(type: ChatListModel.self)
 .value()
 .receive(on: DispatchQueue.main)
 .eraseToAnyPublisher()
}
</code></pre>
Later in viewModel
<pre><code>private var subscriptions: Set&lt;AnyCancellable&gt; = []
// some func
 dataManager.fetchChats()
 .sink {[weak self] completion in
 guard let self = self else { return }
 switch completion {
 case .failure(let error):
 switch error.responseCode {
 case 401:
 //do something with code
 default:
 print(error.responseCode)
 }
 print(&quot;All errors:\(error)&quot;)
 case .finished:
 break
 }
 } receiveValue: {[weak self] message in
 guard let self = self else { return }
 self.message = message
 }
 .store(in: &amp;subscriptions)
</code></pre>

I am currently using Alamofire which contains Combine support and using it following way:
<pre class="lang-swift prettyprint-override"><code> let request = AF.request(endpoint)

 ...
 request
 .publishDecodable(type: T.self, decoder: decoder)
 .value()
 .eraseToAnyPublisher()
</code></pre>
This will publish result and <code>AFError</code> but from subscriber's <code>.sink</code>, I can't find anywhere to get the HTTP status code. What's the best way to get the status code in subscriber?

我目前正在使用Alamofire，它包含了组合支持，并使用它的方式如下：    let request = AF.request(endpoint)    ...    request            .publishDecodable(type: T.self, decoder: decoder)       ...
