A proxy is not a ServiceStack Service you call with a DTO, it’s acts like a proxy which forwards the HTTP request to the specified url.
You can call it with any HTTP Client, here’s an example using HTTP Utils:
using (var fs = new FileStream(savedFilePath, FileMode.OpenOrCreate))
{
var bytes = fs.ReadFully();
$$"{baseUrl}/proxy".AddQueryParam("url", "http://192.*.*.*/upfile/abc/1.xls")
.PostBytesToUrl(bytes, contentType:"application/vnd.ms-excel");
}
Note I haven’t tested it, but you’d use it with something like the above.
For future reference the IRequiresRequestStream interface is an indicator that the Service is not meant to be called with a DTO + Service Client, it suggests that the Service intends to reads raw bytes directly from the HTTP Request Body.
I have accord to your advice to change the code, my purpose is want to get the Excel from url through proxy,
the excel address can’t visit directly, but can visit by proxy.
private void button1_Click(object sender, EventArgs e)
{
using (new WaitDialogForm())
using (var app = AppService)
{
var abc = "abc.test";
var url = "http://192.*.*.*/upfile/abc/1.xls";
var requestUrl = f.ApiUrl + "/proxy";
var jwtToken = GetBearerToken();
logger.Info($"jwtToken: {jwtToken}");
logger.Info($"requestUrl: {requestUrl}");
var respose = requestUrl.AddQueryParam("Url", url)
.PostBytesToUrl(requestBody: abc.ToUtf8Bytes()
, contentType: "application/vnd.ms-excel"
, requestFilter: req => req.AddBearerToken(jwtToken));
logger.Info($"bytes:{respose.SerializeToString()}");
var savedFilePath = "C:\\1.xls";
using (var ms = new MemoryStream(respose))
using (var fs = new FileStream(savedFilePath, FileMode.OpenOrCreate))
{
ms.WriteTo(fs);
ms.Close();
fs.Close();
}
}
}
protected virtual IJsonServiceClient GetClient() => new JsonServiceClient(f.ApiUrl);
private string GetBearerToken()
{
var authClient = GetClient();
var bearerToken = authClient.Send(new Authenticate
{
provider = "credentials",
UserName = userName,
Password = passWord,
}).BearerToken;
return bearerToken;
}
it run will get error, (405)method not allowed. , I didn’t restrict the methods .
You should get familiar with these HTTP tools in order to diagnose application issues like this, you’re in the best position to diagnose your local issues, we can’t tell what it is from here.
That only shows the proxy, you can’t tell if the response originated from the downstream server by looking at the proxy http traffic. Have you tried debugging the Proxy Service? i.e. putting a breakpoint on the Exception?
Sorry, It’s my problem , in the code ProxyServcie is url.SendBytesToUrl, but I set the url is a excel link, so it will get Method Not Allowed.
In Fact, I only want to get the excel content through proxy, the below code is enough. thanks.
