AFNetworking 3.0 Code=-1016 错误解决方案

导入AFNetworking类库（请参考：iOS 9 导入类库全面详尽过程（Ruby安装->CocoaPods安装->导入类库））之后，然后小伙伴们就可以照着如下官方文档欢乐地写代码。

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; [manager GET:@"http://blog.csdn.net/sps900608" parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) { NSLog(@"Success: %@", responseObject); } failure:^(NSURLSessionTask *operation, NSError *error) { NSLog(@"Error: %@", error); }];

或是用Swift：

let sessionManager = AFHTTPSessionManager() sessionManager.GET("http://blog.csdn.net/sps900608", parameters: nil, progress: nil, success: { (task, responseObject) in NSLog("Success:\(responseObject)"); }) { (task, error) in NSLog("Error:\(error)") }

结果就妥妥地报错了

Error:Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: text/html" UserInfo={com.alamofire.serialization.response.error.response= { URL: http://m.blog.csdn.net/blog/index?username=sps900608 } { status code: 200, headers { "Cache-Control" = private; Connection = "keep-alive"; "Content-Encoding" = gzip; "Content-Type" = "text/html; charset=utf-8"; Date = "Fri, 20 May 2016 09:01:39 GMT"; "Keep-Alive" = "timeout=20"; Server = openresty; "Transfer-Encoding" = Identity; Vary = "Accept-Encoding"; "X-AspNetMvc-Version" = "3.0"; "X-Powered-By" = "PHP 5.4.28"; } }, NSErrorFailingURLKey=http://m.blog.csdn.net/blog/index?username=sps900608

搜索 “Request failed: unacceptable content-type: text/html” 的解决方案，会有很多人告诉你去修改AFURLResponseSerialization类中的

self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", nil];

改为：

self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript"，@"text/html", nil];

或者在AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];之后加一行这样的代码：

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html", nil];

接下来又有可能报另一个错误

Error:Error Domain=NSCocoaErrorDomain Code=3840 "JSON text did not start with array or object and option to allow fragments not set." UserInfo={NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}

为了从根本上解决 Code=-1016 错误，并避免 Code=3840 错误，其实只需要一行代码就能搞定：

sessionManager.responseSerializer = [AFHTTPResponseSerializer serializer]

Swift:

sessionManager.responseSerializer = AFHTTPResponseSerializer()

示例代码：

import UIKit import AFNetworking class ViewController: UIViewController { @IBOutlet var webView: UIWebView! override func viewDidLoad() { super.viewDidLoad() let sessionManager = AFHTTPSessionManager() sessionManager.responseSerializer = AFHTTPResponseSerializer() sessionManager.GET("http://blog.csdn.net/sps900608", parameters: nil, progress: nil, success: { (task, responseObject) in let data = responseObject as! NSData self.webView.loadData(data, MIMEType: "text/html", textEncodingName: "utf-8", baseURL: NSURL()) }) { (task, error) in NSLog("Error:\(error)") } // Do any additional setup after loading the view, typically from a nib. } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } }
