Google Adwords API

Google Adwords API 分正式API和测试API。

基中正式API是需要收取费用，Google将以API单位收费；而测试API(Sandbox)中的则不收取任何费用，但有些API返回的结果是Google定义好的，不怎么好测试！Google也是近期刚发布的V13版本，以前是V12，因为我Email账号是没缴费的账号，所以是不能用正式的API来调试Service的。充值后Google会先扣掉50块，不明所以！

如在项目中分别引用两类API：

• 正式API

　　URL:https://adwords.google.com/api/adwords/v13/AccountService?wsdl

　　引用命名：GoogleAdwords.AccountService

• 测试API

　　URL:https://sandbox.google.com/api/adwords/v13/AccountService?wsdl

　　引用命名：GoogleAdwords.Sandbox.AccountService

代码如下，分别测试时就会有如下错误：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.Web;

//正式API
using GAE.CL.GoogleAdwords.AccountService;
//测试API
//using GAE.CL.GoogleAdwords.Sandbox.AccountService;

namespace GAE.CL.ClassLibrary
{
    public class Main
    {
        #region 常量
        private static string email = "itblackhole@gmail.com";
        private static string password = "******";
        private static string useragent = "INSERT_COMPANY_NAME: AdWords API DotNet Sample Code";
        private static string developerToken = "itblackhole@gmail.com++CNY";
        private static string applicationToken = "INSERT_APPLICATION_TOKEN_HERE";
        #endregion 常量


        public void getClientAccounts(out string[] customerClientEmail)
        {
            customerClientEmail = null;
            try
            {
                // Set up service connection.
                AccountService service = new AccountService();

                // Define SOAP headers.
                service.emailValue = new email();
                service.emailValue.Text = new String[] { email };
                service.passwordValue = new password();
                service.passwordValue.Text = new String[] { password };
                service.useragentValue = new useragent();
                service.useragentValue.Text = new String[] { useragent };
                service.developerTokenValue = new developerToken();
                service.developerTokenValue.Text = new String[] { developerToken };
                service.applicationTokenValue = new applicationToken();
                service.applicationTokenValue.Text = new String[] { applicationToken };

                // Get client accounts.
                string[] loginEmails = service.getClientAccounts();

                // Display login emails.
                if (loginEmails != null)
                {
                    customerClientEmail = loginEmails;
                    foreach (string customerEmail in loginEmails)
                    {
                        HttpContext.Current.Response.Write("Login email is  \"" + customerEmail + "\".<br/>");
                    }
                }
                else
                {
                    HttpContext.Current.Response.Write("当“我的客户中心”(MCC) 帐户修改客户帐户时要使用的标头元素。<br/>");
                }

            }
            catch (Exception e)
            {
                HttpContext.Current.Response.Write(e.ToString() + "<br/>");
            }
        }
    }
}

如果使用正式的API运行上面的代码，就会报“无效的开发者令牌”，如：System.Web.Services.Protocols.SoapException: The developer token is invalid.

如果使用测试的API运行，则会正确的返回如下信息：

Login email is "client_1+itblackhole@gmail.com".
Login email is "client_2+itblackhole@gmail.com".
Login email is "client_3+itblackhole@gmail.com".
Login email is "client_4+itblackhole@gmail.com".
Login email is "client_5+itblackhole@gmail.com".
