以前用的好端端的接口，今天访问居然出错了，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=ErrorDomain=com.alamofire.error.serialization.response Code=-1016"Request failed: unacceptable content-type: text/html"UserInfo=0x7fdfd8729680{com.alamofire.serialization.response.error.response= { URL:http://172.16.1.31:7001/itom/getwork } { status code: 200, headers{

下面是百度出来的答案：
I also encountered the same problem.This means that your server issending"text/html"insteadof the already supported types. After a little search, my solutionwas toadd"text/html"toacceptableContentTypessetinAFURLResponseSerializationclass.Just search for "acceptableContentTypes" andadd@"text/html"tothe set manually. Of course, the ideal solution will be to changethe tpe from the server, but for that you will hade to talk withthe server team.
I hope this helps you. Best regards and
less bugs as possible in the code.
op.responseSerializer.acceptableContentTypes =
[NSSet setWithObject:@"text/html”];
对应到自己的项目里面，我用的是AFNetworking这套网络请求包，需要改的是：
AFURLResponseSerialization.m文件
223行：
self.acceptableContentTypes=[NSSetsetWithObjects:@"application/json",@"text/html",@"text/json",@"text/javascript",nil];
加上斜体部分，其实就是添加一种服务器返回的数据格式。
