报错：Request failed: unacceptable content-type: text/html

错误：

(null) @"NSLocalizedDescription" : @"Request failed: unacceptable content-type: text/html"

原因：

AFNetworking 默认不支持text/html

AFURLResponseSerialization.m 源码 -> self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", nil];

解决办法：

1）在源代码处添加 @"text/html"

2）在自己的代码处加上：

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
