AFNetworking 2.0 - "unacceptable content-type: text/plain"
提问by TomorrowPlusX
I'm using AFNetworking 2.0 to read JSON from a service I'm building (on localhostfor now) in Node. Pretty normal stuff.
我正在使用 AFNetworking 2.0 从我在 Node.js 中构建（localhost现在）的服务中读取 JSON 。很正常的东西。
Node is sending JSON like so:
节点发送 JSON 如下：
res.setHeader('Content-Type','application/json');
res.end( JSON.stringify(...));
My iOS first-pass code is attempting to read that data like so:
我的 iOS 第一遍代码正在尝试像这样读取数据：
typedef void(^NextBlock)();
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager GET:self.newestTimestampURL.absoluteString
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
//NSDictionary *response =
NSLog(@"got %@", responseObject );
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(@"fail %@", error );
}];
This is the error I'm getting:
这是我得到的错误：
Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/plain" UserInfo=0xb783e30 {NSErrorFailingURLKey=http://localhost:3000/api/v1/log/newest, AFNetworkingOperationFailingURLResponseErrorKey=<NSHTTPURLResponse: 0xb656a70> { URL: http://localhost:3000/api/v1/log/newest } { status code: 200, headers {
Connection = "keep-alive";
ContentType = "application/json";
Date = "Fri, 27 Dec 2013 20:58:50 GMT";
"Transfer-Encoding" = Identity;
} }, NSLocalizedDescription=Request failed: unacceptable content-type: text/plain}
I can curl (-i) the url http://localhost:3000/api/v1/log/newestand get the data I'm expecting, and it's application/json as expected. If I load that data in my web browser, I get JSON as expected per dev tools inspector.
我可以卷曲 (-i) urlhttp://localhost:3000/api/v1/log/newest并获取我期望的数据，它是预期的 application/json。如果我在 Web 浏览器中加载该数据，我会按照开发工具检查器的预期获得 JSON。
But using AFNetworking, I get this mysterious "unacceptable content-type: text/plain" error. Any idea?
但是使用 AFNetworking，我得到了这个神秘的“不可接受的内容类型：文本/纯文本”错误。任何的想法？
NOTE: I've never used AFNetworking before, so I'm probably using it incorrectly.
注意：我以前从未使用过 AFNetworking，所以我可能没有正确使用它。

It seems that the server is sending "text/html", and this type is not supported by default. Add @"text/html" for "acceptableContentTypes"
好像是服务器在发送“text/html”，默认不支持这种类型。为“acceptableContentTypes”添加@“text/html”
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];

I have followed the answer posted by @KIO but it did not work in my scenario.
我遵循了@KIO 发布的答案，但它在我的场景中不起作用。
After going with many answers i was able to find solution which worked for me.
在回答了很多答案之后，我找到了对我有用的解决方案。
AFHTTPRequestOperationManager *operation = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:url];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
AFJSONResponseSerializer *jsonResponseSerializer = [AFJSONResponseSerializer serializer];
NSMutableSet *jsonAcceptableContentTypes = [NSMutableSet setWithSet:jsonResponseSerializer.acceptableContentTypes];
[jsonAcceptableContentTypes addObject:@"text/plain"];
jsonResponseSerializer.acceptableContentTypes = jsonAcceptableContentTypes;
operation.responseSerializer = jsonResponseSerializer;

Updated Solution for Swift.
Swift 的更新解决方案。
If you are using AFNetworking in Swift. Then this solution might help you. It will accept most of the content types.
如果您在 Swift 中使用 AFNetworking。那么这个解决方案可能会帮助你。它将接受大多数内容类型。
let manager=AFHTTPRequestOperationManager()
manager.responseSerializer = AFJSONResponseSerializer(readingOptions: NSJSONReadingOptions.AllowFragments) as AFJSONResponseSerializer
manager.requestSerializer = AFJSONRequestSerializer() as AFJSONRequestSerializer
manager.responseSerializer.acceptableContentTypes = NSSet(objects:"application/json", "text/html", "text/plain", "text/json", "text/javascript", "audio/wav") as Set<NSObject>
