在 Azure 函数中，我试图从 MS Graph Converter ( Doc )返回一个 pdf 文件
该文件以 302 Http 状态返回，在本地没什么大不了的，一切正常，但是当我在 azure 函数上发布时，我遇到了这个错误：
502 - Web 服务器在充当网关或代理服务器时收到无效响应。您要查找的页面有问题，无法显示。当 Web 服务器（作为网关或代理）联系上游内容服务器时，它收到了来自内容服务器的无效响应。
我的代码：
IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder
.Create("")
.WithTenantId("")
.WithClientSecret("")
.Build();
ClientCredentialProvider authProvider = new ClientCredentialProvider(confidentialClientApplication);
var graphClient = new GraphServiceClient(authProvider);
var token = await authProvider.ClientApplication.AcquireTokenForClient(new string[] { "https://graph.microsoft.com/.default" }).ExecuteAsync();
HttpClient httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", token.AccessToken);
try
{
var response = await httpClient.GetAsync($"https://graph.microsoft.com/v1.0/drives/{Drive_Id}/items/{Item_Id}/content?format=pdf");
log.LogInformation($"Status Code : {response.StatusCode}");
if (response.StatusCode == System.Net.HttpStatusCode.Redirect)
{
var bytes = await httpClient.GetByteArrayAsync(response.Headers.Location);
return new FileContentResult(bytes, "application/pdf");
}
if (response.StatusCode == System.Net.HttpStatusCode.OK)
{
var bytes = await response.Content.ReadAsByteArrayAsync();
return new FileContentResult(bytes, "application/pdf");
}
}
catch (Exception ex)
{
log.LogInformation($"Error : {ex.Message}");
}
return new NotFoundResult();
我认为有某种配置可以允许 302 临时重定向或类似的东西..
任何帮助都应该不胜感激
