我想运行此代码来获取谷歌API的地方，但它工作正常，当我尝试pagetoken它不起作用，并给我无效的请求。但是如果我在调试中运行它，那么有时它可以正常工作，有些则不行。你能帮忙吗？只工作时调试，但不运行
private string request_google(string link)
{
try
{
// link = HttpUtility.ParseQueryString(link).ToString();
HttpWebRequest webRequest = WebRequest.Create(link) as HttpWebRequest;
webRequest.Timeout = 20000;
webRequest.Method = "GET";
var response = (HttpWebResponse)webRequest.GetResponse();
using (var stream = response.GetResponseStream())
{
var r = new StreamReader(stream);
string responce = r.ReadToEnd();
file_number = file_number + 1;
File.WriteAllText("E:\\google maps\\pharmcy\\places_" + string.Format("text-{0:yyyy-MM-dd_hh-mm-ss-tt-fff}",
DateTime.Now) + "_file" + file_number + " _area_" + area_number + ".txt", responce);
dynamic places_reponce = JsonConvert.DeserializeObject(responce);
if (places_reponce.status == "INVALID_REQUEST")
{
File.WriteAllText("E:\\google maps\\pharmcy\\places_" + string.Format("text-{0:yyyy-MM-dd_hh-mm-ss-tt-fff}",
DateTime.Now) + "_file" + file_number + " _area_" + area_number + "invalid_reques" + ".txt", "The link :" + link);
}
return places_reponce.next_page_token;
}
}
catch (Exception e)
{
File.WriteAllText("E:\\google maps\\pharmcy\\places_" + string.Format("text-{0:yyyy-MM-dd_hh-mm-ss-tt-fff}",
DateTime.Now) + "_file" + file_number + " _area_" + area_number +"error"+ ".txt", "The link :"+link+"\n The Error"+e.ToString());
return null;
}
}
