我正在使用HttpClient进行多部分请求，并成功从服务器获得了多部分响应，一切看起来都很好。

RAW HTTP请求是（并且所有HTTP标头均已正确设置）

--batchquery
Content-Type: application/http
Content-Transfer-Encoding: binary

GET https://myinstance.dynamics.com/api/data/v9.1/adx_externalidentities?fetchXml=<fetch><entity name="adx_externalidentity"><all-attributes /><filter type="and"><condition attribute="adx_username" operator="eq" value="d2d5b3cc-133b-e911-a995-000d3ad1c6f2" /></filter><link-entity name="contact" from="contactid" to="adx_contactid" link-type="outer" alias="__0__"><all-attributes /></link-entity></entity></fetch> HTTP/1.1

--batchquery--

在为内部Section创建自己的解析器之前，我希望可以在Framework中找到一个现有方法（例如StringContent），该方法可以使我返回HttpResponseMessage对象或对该部分的内容，就好像它是标准的httpresponsemessage

private async Task<ResponseData> GetRequest(string requestUrl)
{
    Authorise();

    var mp = new MultipartContent("mixed","batchquery");
    var sb = new StringBuilder();
    sb.AppendLine($"GET {requestUrl} HTTP/1.1");

    var content = new StringContent(sb.ToString());
    content.Headers.ContentType = new MediaTypeHeaderValue("application/http");
    content.Headers.Add("Content-Transfer-Encoding","binary");

    mp.Add(content);

    using (var batchRequest = new HttpRequestMessage
    {
        Method = HttpMethod.Post,Requesturi = BatchRequesturi,Content = mp,})
    {
        batchRequest.Headers.Authorization = new AuthenticationHeaderValue("Bearer",accessToken);

        using (var response = await httpClient.SendAsync(batchRequest))
        {
            var mt = response.Content.Headers.ContentType;

            var boundary = mt.Parameters.FirstOrDefault(x => x.Name == "boundary");
            if (boundary == null) throw new InvalidDataException("Boundary not found in headers");

            var mpr = new MultipartReader(boundary.Value,await response.Content.ReadAsStreamAsync());

            while (true)
            {
                var section = await mpr.ReadNextSectionAsync();
                if (section == null) break;

                var responsedata = new ResponseData
                {
                    Data = await section.ReadAsStringAsync(),StatusCode = response.StatusCode
                };
                return responsedata;
            }
        }
    }
    return null;
}

当我查看我的responseData.Data对象时，看到的是200 OK响应和所有标头，而不仅仅是Json Response数据，就像您直接将Ht​​tpClient与单个{{1} }

response.data包含...

GET
