iOS 使用AFNetworking遇到错误 Request failed: unacceptable content-type: text/html
错误日志：

原因：
不可接受的内容类型 “text/html”
解决方案：
AFJSONResponseSerializer.m中，222行左右
把 这句： self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", nil];
修改为：
self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];
在进行网络请求时出现-1016 是因为只支持
text/json，application/json，text/javascript
你可以添加text/html
一劳永逸的方法是 在
AFURLResponseSerialization.h
里面搜索
self.acceptableContentTypes
然后 在里面 添加
@"text/html",@"text/plain"
这样就可以解决-1016的错误了
但是随之而来的是3840错误
Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x9152780 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}
你会发现出现此错误
怎么办呢
添加如下语句 就可以解决问题了
manger.requestSerializer= [AFHTTPRequestSerializerserializer];
网友评论
传回来的json是text/html，是不可接受格式，那么就是说：
1、你要么让AFNetworking接受传回值是text/html格式；
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
2、要么就把text/html这种json序列化(serializer)成二进制格式(NSData)，然后再解析出来，就是用NSData当中间层。
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
拿到responseObject后，如果外层是字典：
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];
这里并没有审核机制，所以这里“大神”很多，这种问题，读读英文提示，想想谢希仁的《计算机网络》第6章 应用层，第248页，很好理解。

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.}
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/plain", nil];
我的是增加了@"text/plain"
增加manager.requestSerializer = [AFHTTPRequestSerializer serializer]; 这个是有用的
