AFNetworking-偶尔会收到“不可接受的内容类型:application / json”在http响应 [英] AFNetworking - occasionally get "unacceptable content type: application/json" on http response
问题描述
我不知道为什么AFNetworking 2.0会抛出此消息。我的理解是application / json是默认的序列化方案,因此如果服务器返回内容类型为:application / json的JSON,为什么AFNetworking会引发此错误?
I can't figure out why this message is being thrown by AFNetworking 2.0. My understanding is that application/json is the default serialization scheme, so if the server returns JSON with content-type:application/json, why would AFNetworking throw this error?
Failure with messages Error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: application/json" UserInfo=0x17e2ed60 {com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x17e84100> { URL: http://XXX/XXX/XXX } { status code: 200, headers {

在代码块中注释了带有X的URL。仅在某些情况下会发生这种情况,并导致请求失败。如果我发出另一个请求,它将成功。
Commented out URL's with X's in the code block. This only happens sometimes, and it causes the request to fail. If I issue another request, it succeeds.
我正在使用AFHTTPSessionManager单例发出所有请求。
I'm using an AFHTTPSessionManager singleton to issue all requests.
推荐答案
尝试以下操作:
sessionManager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", nil];
