Question

我想在HTTPHeaderField中设置NSInteger值。以下是我的代码

NSInteger user_id =1234;
if ([AFNetworkReachabilityManager sharedManager].reachable) {

    AFHTTPRequestOperationManager *afRequestOpManager = [AFHTTPRequestOperationManager manager];
    afRequestOpManager.requestSerializer = [AFJSONRequestSerializer serializer];
    afRequestOpManager.responseSerializer = [AFJSONResponseSerializer serializer];
    [afRequestOpManager.requestSerializer setValue:user_id forHTTPHeaderField:@"user-id"];
    [afRequestOpManager PUT:strUrl parameters:nil success: ^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSLog(@"JSON: %@", responseObject);
     }failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         NSLog(@"JSON: %ld", error.code);
     }];

但是我无法将user_id设置为整数。

Answer 1

传递给setValue的类型是NSString。要将NSInteger转换为NSString，请使用：[NSString stringWithFormat:@"%ld", (long)user_id]

Answer 2

HTTP标头值只能采用字符串值，不能包含任何其他数据类型值

因此，请将您的用户ID转换为字符串，如下所示

[NSString stringWithFormat:@"%d",user_id]

然后在标题中设置值，也只是为了约定，始终在自定义http标头前加上 X - ，这样你的标题就会变成X-user-id
