c# - 微软图: Invalid batch payload format

Question

我正在尝试批处理update用户列表，使用 example from the docs 之后的 MS Graph Batch API但收到错误“消息:无效的批处理负载格式。”

// batch disable all users
var allUsers = await GraphHelper.client.Users.Request().Select("id").GetAsync();

var batchRequestContent = new BatchRequestContent();
allUsers.Select(user =>
{
  var httpRequest = GraphHelper.client.Users[user.Id].Request().GetHttpRequestMessage();
  httpRequest.Method = HttpMethod.Put;
  httpRequest.Content = GraphHelper.client.HttpProvider.Serializer.SerializeAsJsonContent(new User { AccountEnabled = false });
  return batchRequestContent.AddBatchRequestStep(httpRequest);
});
var userUpdateResult = await GraphHelper.client.Batch.Request().PostAsync(batchRequestContent);

下面用于禁用用户的代码无需批处理即可运行。

var user = new User { AccountEnabled = false };
var userResult = await GraphHelper.client.Users[id].Request().UpdateAsync(user);

如果我使用 lambda 运算符，而不是将其更改为 foreach 循环并添加批处理请求，我也能得到相同类型的错误，如下所示。

static async Task<BatchResponseContent> BulkUpdate()
{
    var allUsers = await GraphHelper.graphClient.Users.Request().Top(10).Select("id").GetAsync();

    var batchRequestContent = new BatchRequestContent();
    foreach(var items in allUsers)
    { 
        var httpRequest = GraphHelper.graphClient.Users[items.Id].Request().GetHttpRequestMessage();
        httpRequest.Method = HttpMethod.Patch;
        httpRequest.Content = GraphHelper.graphClient.HttpProvider.Serializer.SerializeAsJsonContent(new User { AccountEnabled = false });
        batchRequestContent.AddBatchRequestStep(httpRequest);
    }
    var userUpdateResult = await GraphHelper.graphClient.Batch.Request().PostAsync(batchRequestContent);
    return userUpdateResult;
}

这样我就可以将批量请求添加到batchRequestContent变量中，如下图所示。

注意:JSON 批量请求当前为 limited最多 20 个单独请​​求。
