iOS"Request failed: unacceptable content-type: text/html"

测试好端端的接口 出错了，但是再用浏览器测试，发现可
以正常返回数据，甚是奇怪啊。
下面是错误信息：
获取服务器响应出错 error=Error Domain=com.alamofire.error.serialization.response

下面是百度出来的答案：
I also encountered the same problem. This means that your
server is sending "text/html" instead of the already
supported types. After a little search, my solution was
to add "text/html" to acceptableContentTypes set in
AFURLResponseSerialization class. Just search for
"acceptableContentTypes" and add @"text/html" to the set
change the tpe from the server, but for that you will hade to talk with the server team.
I hope this helps you. Best regards and less bugs as
possible in the code.
op.responseSerializer.acceptableContentTypes = [NSSet
setWithObject:@"text/html”];

self.acceptableContentTypes = [NSSetsetWithObjects:@"application/json",
@"text/html",@"text/json",@"text/javascript", nil];
其实就是添加一种服务器返回的数据格式。
