HttpClient和设置Authorization头信息

Question

HttpClient和设置Authorization头信息

9

我想对Basecamp API发起简单的请求，我按照提供的说明添加了示例用户代理和我的凭据，但是我不断收到403 Forbidden的响应。

我的凭据肯定是正确的，那么是我的请求/凭据设置不正确吗？

这是我有的（删除了个人信息）：

var httpClient = new HttpClient();
var content = new FormUrlEncodedContent(new[] { new KeyValuePair<string, string>("User-Agent", "MyApp [EMAIL ADDRESS]") });

httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
            Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes(string.Format("{0}:{1}", "[USERNAME]", "[PASSWORD]"))));

var response = await httpClient.PostAsync("https://basecamp.com/[USER ID]/api/v1/projects.json", content);
var responseContent = response.Content;

using (var reader = new StreamReader(await responseContent.ReadAsStreamAsync()))
{
     Console.WriteLine(await reader.ReadToEndAsync());
}

初步查看他们的文档似乎表明，projects.json 终端接受以下内容作为POST请求的主体：

{
    "name": "This is my new project!",
    "description": "It's going to run real smooth"
}

您将User-Agent作为POST请求体发送。我建议您按以下方式更改代码：

    var credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(string.Format("{0}:{1}", "[USERNAME]", "[PASSWORD]")));
    using (var httpClient = new HttpClient())
    {
        httpClient.DefaultRequestHeaders.Add("User-Agent", "MyApp [EMAIL ADDRESS]");
        httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", credentials);
        var response = await httpClient.PostAsJsonAsync(
            "https://basecamp.com/[USER ID]/api/v1/projects.json",
            new {
                name = "My Project",
                description = "My Project Description"
            });

        var responseContent = await response.Content.ReadAsStringAsync();
        Console.WriteLine(responseContent);
    }

根据文档，此操作会发布载荷，并将您的用户代理设置为应有的标头。
