如何输入我的用户名和密码？需要一些帮助，我是 C# 新手

Answer 1

要完成这项工作，您首先需要authenticate 以便为给定的可用于访问数据的谷歌网站获取有效的SID。以下是实现此目的的方法：

class Program
{
    static void Main(string[] args)
    {
        using (var client = new WebClient())
        {
            // TODO: put your real email and password in the request string
            var response = client.DownloadString("https://www.google.com/accounts/ClientLogin?accountType=GOOGLE&Email=youraccount@gmail.com&Passwd=secret&service=trendspro&source=test-test-v1");
            // The SID is the first line in the response
            var sid = response.Split('\n')[0];
            client.Headers.Add("Cookie", sid);
            byte[] csv = client.DownloadData("http://www.google.com/insights/search/overviewReport?q=test&cmpt=q&content=1&export=2");

            // TODO: do something with the downloaded csv file:
            Console.WriteLine(Encoding.UTF8.GetString(csv));
            File.WriteAllBytes("report.csv", csv);
        }
    }
}

好吧，这几天就变了。

现在您必须通过身份验证而不是 SID。

所以现在的代码是：

class Program
{
    static void Main(string[] args)
    {
        using (var client = new WebClient())
        {
            // TODO: put your real email and password in the request string
            var response = client.DownloadString("https://www.google.com/accounts/ClientLogin?accountType=GOOGLE&Email=youraccount@gmail.com&Passwd=secret&service=trendspro&source=test-test-v1");
            // The Auth line
            var auth = response.Split('\n')[2];
            client.Headers.Add("Authorization", "GoogleLogin " + auth);
            byte[] csv = client.DownloadData("http://www.google.com/insights/search/overviewReport?q=test&cmpt=q&content=1&export=2");

            // TODO: do something with the downloaded csv file:
            Console.WriteLine(Encoding.UTF8.GetString(csv));
            File.WriteAllBytes("report.csv", csv);
        }
    }
}

现在它又对我有用了。
