使用RestSharp获取Solvemedia图像

Question

I'm developing an application which needs to make a query on a website to extract certain data, such as the user's name, points / remaining balance etc.

I present a problem in the login, the client needs to solve a captcha solvemedia to be able to enter the website, I would like to extract the image of this captcha and show it to the client but I am having problems to extract it, i'm trying to do it through http requests with RestSharp, the reason I do not do it with a webbrowser or selenium is that it spends a lot more resources.

i try this:

RestClient restClient = new RestClient(@"//api-secure.solvemedia.com/papi/media?c=2@gAB09NHSertXLv3TnpobmKDxvkjsaT4m@X4wLMdkN.u0ENU8bgrS3KH9APTC4lJjokJaIfZePPIgNLL84QkOaQlXcxzHvOVTTU98Of7mo8BoC0QQuiH1RMqMrGof6BbL-tReeY8AHhPA7-nwvQKLqUEXQwTL4HhLXfZVre9jccpqQxFGIRYZH1ZQoAKCV5k1TGCLXXP9vMVsJFntDNz6Ozik02MANT1siBJRYTNIpGcj6p6Gbq5j0HvQChz7jtgdzwlj7nee0BdZphpg27ikQlVB5IUelMvSjzNNvPZawB9YbC9v6zyJngNQaJIJku2SPJkhFXIK0uoA;w=300;h=150;fg=000000;bg=f8f8f8");
var fileBytes = restClient.DownloadData(new RestRequest("#", Method.GET));
File.WriteAllBytes(Path.Combine(directory, "poster-got.jpg"), fileBytes);

The problem with this is that I only get an image that says "Media Error", Is there any way to get the image that is sent when you request the login page? Can it be done with restsharp? , if not with what library could I do it?

For downloading image I use https://github.com/jgiacomini/Tiny.RestClient

But when I try to view your image in in my browser I have a media error. I think you use a wrong url.

In your case using Tiny.RestClient;

var client = new TinyRestClient(new HttpClient(), "@"http//api-secure.solvemedia.com");
FileInfo fileInfo = await client.
GetRequest("papi/media").
AddQueryParameter("2@gAB09NHSertXLv3TnpobmKDxvkjsaT4m@X4wLMdkN.u0ENU8bgrS3KH9APTC4lJjokJaIfZePPIgNLL84QkOaQlXcxzHvOVTTU98Of7mo8BoC0QQuiH1RMqMrGof6BbL-tReeY8AHhPA7-nwvQKLqUEXQwTL4HhLXfZVre9jccpqQxFGIRYZH1ZQoAKCV5k1TGCLXXP9vMVsJFntDNz6Ozik02MANT1siBJRYTNIpGcj6p6Gbq5j0HvQChz7jtgdzwlj7nee0BdZphpg27ikQlVB5IUelMvSjzNNvPZawB9YbC9v6zyJngNQaJIJku2SPJkhFXIK0uoA;w=300;h=150;fg=000000;bg=f8f8f8").
DownloadFileAsync("c:\"poster-got.jpg");
