Error Domain=com.alamofire.error.serialization.response Code=-1016 image/jpeg application/octet-stre

具体错误代码

error Domain=com.alamofire.error.serialization.response Code=-1016 "Request failed: unacceptable content-type: image/jpeg" UserInfo={com.alamofire.serialization.response.error.response=0x170225100> { URL: https:// } { status code: 200, headers {
    "Accept-Ranges" = bytes;
    Connection = "keep-alive";
    "Content-Length" = 7912;
    "Content-Type" = "application/octet-stream";
    Date = "Wed, 18 Jan 2017 08:35:52 GMT";
    Etag = "\"587c3b57-1ee8\"";

    Server = nginx;
    "Strict-Transport-Security" = "max-age=15768000";
} },

修改：

//1 在这里添加@"image/jpeg"
 manager.responseSerializer.acceptableContentTypes = [NSSet setWithArray:@[@"application/json",
                                                                              @"text/html",
                                                                              @"text/json",
                                                                              @"text/plain",
                                                                              @"text/javascript",
                                                                              @"text/xml",@"image/jpeg",
                                                                              @"image/*"]];

   //如果出现  error: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.}有可能requestSerializer设置不对

   // manager.requestSerializer = [AFJSONRequestSerializer serializer];


    manager.requestSerializer = [AFHTTPRequestSerializer serializer];
