AFN请求问题，{ Status Code: 404, Headers { "Content-Language" = (en); "Content-Length" = (1175);

//404,406除了参数，路径错了，有可能都是需要使用multipart/form-data格式提交

{ Status Code: 404, Headers { 

"Content-Language" =    (en);

"Content-Length" =    (1175);

"Content-Type" =    ("text/html;charset=utf-8");

Date =    ("Tue, 14 Nov 2017 02:49:51 GMT");

} }}

因为做测试以下是直接写死的参数和路径

  NSString *boundary =@"wfWiEWrgEFA9A78512weF7106A";//这个没有特殊要求

    NSString *str = [NSString  stringWithFormat:@"multipart/form-data; boundary=%@",boundary];

    

     [manager1.requestSerializer  setValue:str  forHTTPHeaderField:@"Content-Type"];

     manager1.responseSerializer.acceptableContentTypes  = [NSSet  setWithObjects:@"application/json",@"text/json",@"text/javascript",nil];

    [manager1 POST:@"https://117.48.205.100:443/plant/mob/user/register"parameters:reqParamsprogress:^(NSProgress *_Nonnull downloadProgress) {

    } success:^(NSURLSessionDataTask *_Nonnull task,id _Nullable responseObject) {

        NSString *unicodeStr = [NSString  stringWithCString:[[responseObject   objectForKey:@"msg"]UTF8String]  encoding:NSUTF8StringEncoding];

        NSLog(@"responseObject====%@====%@",responseObject,unicodeStr);  

    } failure:^(NSURLSessionDataTask *_Nullable task,NSError * _Nonnull error) {

        

        NSLog(@"%@",error);

        

    }];
