Question

我是AWS和CloudSearch的新手。我写了一个非常简单的应用程序，它将docx文档（已经使用cs-import-document转换为JSON格式）上传到我的搜索域。

代码非常简单：

using (var searchdomainclient = new AmazonCloudSearchDomainClient("http://search-xxxxx-xysjxyuxjxjxyxj.ap-southeast-2.cloudsearch.amazonaws.com"))
{

    // Test to upload doc                            

    var uploaddocrequest = new UploadDocumentsRequest()
    {
        FilePath = @"c:\temp\testsearch.sdf",  //docx to JSON already
        ContentType =  ContentType.ApplicationJson

    };
    var uploadresult = searchdomainclient.UploadDocuments(uploaddocrequest);

   }

然而，我得到的例外是：＆＃34;缺少根元素。＆＃34;

以下是我要上传的sdf文件中的JSON内容：

[{
    "type": "add",
    "id": "c:_temp_testsearch.docx",
    "fields": {
        "template": "Normal.dotm",
        "application_name": "Microsoft Office Word",
        "paragraph_count": "1",
        "resourcename": "testsearch.docx",
        "date": "2014-07-28T23:52:00Z",
        "xmptpg_npages": "1",
        "page_count": "1",
        "publisher": "",
        "creator": "John Smith",
        "creation_date": "2014-07-28T23:52:00Z",
        "content": "Test5",
        "author": "John Smith",
        "last_modified": "2014-07-29T04:22:00Z",
        "revision_number": "3",
        "line_count": "1",
        "application_version": "15.0000",
        "last_author": "John Smith",
        "character_count": "5",
        "character_count_with_spaces": "5",
        "content_type": "application/vnd.openxmlformats-officedocument.wordprocessingml.document"
    }
}]

那么我的做法有什么不对？

谢谢堆！

P.S。我可以手动将docx doc上传到该搜索doamin并使用C＃代码来应用搜索。

我不确定它是否与此有关。在堆栈跟踪中，我发现它尝试解析为XML文件而不是JSON。但是从我的代码中我已经设置了ContentType = JASON，但似乎没有效果。

Answer 1

您的文档ID包含无效字符（句点和冒号）。来自https://aws.amazon.com/articles/8871401284621700：

在您上传到的所有文档中，ID必须是唯一的域，可以包含以下字符：a-z（小写字母），0-9和下划线字符（_）。文件ID必须以字母或数字开头，最长可达64个字符。

目前还不清楚您发布的端点，但您可能也遇到问题。

SDK版本2.2.2.0我有完全相同的例外。当我将SDK更新到版本2.2.2.1时，异常消失了。

AWS CloudSearch无法上传文档
