你可以用AFHTTPRequestOperationManager解决一切问题，遇到你的这个问题，你可以像这么写： 
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];//设置相应内容类型 
[manager POST:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) { 
} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
}];

如果是授权失败

回调网址与授权网址不应该是一致的
