I use a gesture to get and show the selected words translate result ( link), but Google translates service is totally left our Country, I need to modify the Host to access or use the Proxy which I prefer. I find the following which sends a request by the Proxy, and I can't get the result after the gesture. Code:WebProxy proxyObject = new WebProxy("http://proxyserver:80/", true);
// HttpClient lifecycle management best practices:
// https://learn.microsoft.com/dotnet/fundamentals/networking/http/httpclient-guidelines#recommended-use
HttpClient client = new HttpClient(new HttpClientHandler
{
Proxy = proxyObject
});
A part of my gesture code Code:
var proxyObject = new System.Net.WebProxy("127.0.0.1:7890", true);
var httpHandler = new HttpClientHandler();
httpHandler.AutomaticDecompression = host.flags(DecompressionMethods.GZip, DecompressionMethods.Deflate);
var client = new HttpClient(httpHandler
{
Proxy = proxyObject
});
var response;
var result;
var json;
var proxy;
client.BaseAddress = new Uri("https://translate.googleapis.com/translate_a/");
response = client.GetAsync("single?client=gtx&sl=zh-CN&tl=en&dt=t&q=" + text).Result;
result = response.Content.ReadAsStringAsync().Result;
json = JSON.parse(result);

 If it is necessary for the environment to test, my PC can be remoted with some suitable remote program. Edited by user Thursday, November 3, 2022 1:49:47 PM(UTC)

Try this: Code:var text = "test"; //Just so this code is complete by itself
try {
var httpHandler = new HttpClientHandler();
httpHandler.Proxy = new System.Net.WebProxy("127.0.0.1:7890", true);
httpHandler.AutomaticDecompression = host.flags(DecompressionMethods.GZip, DecompressionMethods.Deflate);
var client = new HttpClient(httpHandler);
var response;
var result;
var json;
var proxy;
client.BaseAddress = new Uri("https://translate.googleapis.com/translate_a/");
response = client.GetAsync("single?client=gtx&sl=zh-CN&tl=en&dt=t&q=" + text).Result;
result = response.Content.ReadAsStringAsync().Result;
json = JSON.parse(result);
} finally {
// IMPORTANT! Make sure to dispose these or it can lead to a memory leak
httpHandler.Dispose();
client.Dispose();
}

Also, their example has a syntax error: Code:HttpClient client = new HttpClient(new HttpClientHandler
{
Proxy = proxyObject
});
Should be: Code:HttpClient client = new HttpClient(new HttpClientHandler()
{
Proxy = proxyObject
});
I'm not sure if that object initialization syntax would translate into S+ anyway, but it is still funny that they messed up in their documentation. Code://This:
var x = new HttpClientHandler()
{
Proxy = proxyObject
};
//Is the same as:
var x = new HttpClientHandler();
x.Proxy = proxyObject;

Wow, I just add this line in my original code, and it works well to get the translated result. httpHandler.Proxy = new System.Net.WebProxy("127.0.0.1:7890", true); But when I change to the try…finally…, it will show this ERROR  Edited by user Thursday, November 3, 2022 1:50:47 PM(UTC)

Hmm, that doesn't seem to make sense  Maybe it has something to do with asynchronous calls? Try putting it after the json line. As long as you're not getting a script error, it would be fine and get disposed.
