Swift 3中的Alamofire与iOS 8

Question

我已经更新到最新版本的Xcode（8），并且在将代码升级到Swift 3之后，Alamofire突然停止工作并抛出许多错误。

经过大量研究，我发现Alamofire for Swift 3与iOS9 +兼容，所以现在我必须找到另一个适用于iOS8 +的版本。

你知道我应该如何为iOS8制作与Alamofire相同的功能？

我没有找到Alamofire for iOS 8的“真实”选择，所以我尝试使用Apple Swift本身的URLRequest。

因此，这里是我终于得到了尝试，尝试后（即使没有SwiftyJSON）的例子：

func searchPosts() -> [Post] { 
    var request = URLRequest(url: URL(string: "https://www.mywebsite.com/searchPosts.php")!) 
    request.httpMethod = "POST" 
    let postString = "" 
    request.httpBody = postString.data(using: .utf8) 
    request.addValue("application/json", forHTTPHeaderField: "Content-Type") 
    request.addValue("application/json", forHTTPHeaderField: "Accept") 

    let task = URLSession.shared.dataTask(with: request) { data, response, error in 

     if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { 
      print(httpStatus.statusCode) 
      self.showError() 
     } else { 
      do { 
       self.listPosts = [Post]() 
       // Convert NSData to Dictionary where keys are of type String, and values are of any type 
       let json = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as! [String:AnyObject] 

       for field in json["posts"] as? [AnyObject] ?? [] { 

        // Create "Post" object 
        let post = Post(
         id: (field["id"])! as! String, 
         title: (field["title"] as! String), 
         alias: (field["alias"] as! String), 
         catid: (field["catid"] as! String), 
         catname: (field["catname"] as! String), 
         date: (field["date"] as! String), 
         image: (field["image"] as! String), 
         introtext: (field["introtext"] as! String), 
         fulltext: (field["fulltext"] as! String) 
        ) 
        self.listPosts.append(post) 
       } 

       DispatchQueue.main.async { 
        self.tableView.reloadData() 
       } 
      } catch { 
       self.showError() 
      } 
     } 
    } 

    task.resume() 

    return listPosts 
} 

我希望这可以帮助其他开发人员。如果有人发现另一个可能的解决方案，我会非常感激。
