如何在Blazor WASM客户端中访问Httpclient标头

private readonly HttpClient _httpClient;

public HttpClientService(HttpClient httpClient)
{
    _httpClient = httpClient;
}

public async Task<HttpResponseMessage> GetWithHeadersAsync(string url, Dictionary<string, string> headers)
{
    var request = new HttpRequestMessage(HttpMethod.Get, url);

    foreach (var header in headers)
    {
        request.Headers.Add(header.Key, header.Value);
    }

    return await _httpClient.SendAsync(request);
}

@page "/example"
@inject HttpClientService HttpClientService

<button @onclick="GetWithHeaders">Get With Headers</button>

@code {
    private async Task GetWithHeaders()
    {
        var url = "https://example.com/api/data";
        var headers = new Dictionary<string, string>
        {
            { "Authorization", "Bearer your_token" },
            { "CustomHeader", "CustomValue" }
        };

        var response = await HttpClientService.GetWithHeadersAsync(url, headers);

        // 处理响应
        if (response.IsSuccessStatusCode)
        {
            var content = await response.Content.ReadAsStringAsync();
            // 处理返回的内容
        }
        else
        {
            // 处理错误
        }
    }
}
