c# - 如何从标准中获取 ip 地址信息？

Question

我正在使用 Google Adwords，目前无法获取具体信息。在我的 Adwords 帐户上，我将“IP 地址排除”设置为 3 个 IP。我想从我的代码中获取此 IP:

AdWordsUser user = new AdWordsUser();
var campaignService = (CampaignCriterionService)user.GetService(AdWordsService.v201506.CampaignCriterionService);
int offset = 0;
        int pageSize = 500;

        var page = new CampaignCriterionPage();
        String awql = "SELECT Id where IsNegative = true ORDER BY Id ASC LIMIT " + offset + "," + pageSize;
try
        {
            do
            {   
                page = campaignService.query(awql);

                // Display the results.
                if (page != null && page.entries != null)
                {
                    int i = offset;
                    foreach (var item in page.entries)
                    {
                        var t = item; //my work logic here ....                           
                        i++;
                    }
                }
                offset += pageSize;
            } while (offset < page.totalNumEntries);
            Debug.WriteLine("Number of items found: {0}", page.totalNumEntries);
        }
        catch (Exception e)
        {
            throw new System.ApplicationException("Failed to retrieve campaigns", e);
        }

查询返回结果数:3，但没有关于 ipAddress 的实际信息(ipAddress 包含 null)。

我能做什么？

Answer 1

不幸的是，我不相信 AWQL 会为被阻止的 IP 地址提供选择器。在任何情况下，它肯定不会随您在上面使用的 AWQL 语句一起提供，该语句只会带回 Id 字段:

String awql = "SELECT Id where IsNegative = true ORDER BY Id ASC LIMIT " + offset + "," + pageSize; try

这就是您的响应中值为空的原因。

我认为唯一可行的方法是亲自动手为该服务使用 Selector 和 Predicate 对象，并使用 get() 方法而不是 query() 方法。

这个解决方案适用于我(诚然适用于更高版本的 API)

var campaignCriterionService = (CampaignCriterionService)user.GetService(AdWordsService.v201601.CampaignCriterionService);
int offset = 0;
int pageSize = 500;

var page = new CampaignCriterionPage();

try
{
    do
    {
        page = campaignCriterionService.get(new Selector
        {
            fields = new string[] { IpBlock.Fields.Id, IpBlock.Fields.IpAddress },
            predicates = new Predicate[]
            {
                new Predicate
                {
                    field = IpBlock.Fields.CriteriaType,
                    @operator = PredicateOperator.EQUALS,
                    values = new string[] { "IP_BLOCK" }
                }
            }
        });

        // Display the results.
        if (page != null && page.entries != null)
        {
            int i = offset;
            foreach (var item in page.entries)
            {
                var t = item; //my work logic here ....                           
                i++;
            }
        }
        offset += pageSize;
    } while (offset < page.totalNumEntries);
    Debug.WriteLine("Number of items found: {0}", page.totalNumEntries);
}
catch (Exception e)
{
    throw new System.ApplicationException("Failed to retrieve campaigns", e);
}
