使用 C# 将 dynamodb json 转换为普通 json

Question

我正在尝试使用 C# 将 dynamodb json 转换为普通 json，实际上对于对象类型 M 我无法实现转换仍然得到如下结果

                                "Type": 0
                            }
                        ]
                    },
                    "source": {
                        "Value": “test Service",
                        "Type": 0
                    },
                    "incidentId": {},
                    "status": {
                        "Value": "500",
                        "Type": 1
                    }
                }
            ]
        }
    } }

实际上是使用Document.FromAttributeMap()来获得上述结果，但我仍然需要让它看起来像一个普通的 json 值，比如

 {
    "RecordDetails": {
        "firstName": “32432-ere”,
        "lastName": "32432-ere",
        "contactInformation": {
            "addressLine1": "10 Downing st",
            "addressLine2": “”,
            "city": "Portand",
            "phone": "555-555-5555",
            "email": "jdoe@abc.com”
        },
        "employer": {
            “Id”: “test:1473969"
        },
        "middleName": "A",
        "id": "637934995361318864",
        "title": "Dr.",
        "userId": “ererew-2332432”,
        "earnedDegrees": "MD.",        },
    "ValidationStatus":"Passed",
    "TypeOfRecord": “test”,
    "TenantCode": “demo2”,
    "Action":  "create",
    "TenantHostName": “t1.demo.com",
    "ImportJobId": “erewre7777-322h23h”,
    "ValidationMessage": "No Errors",
    "ProcessingResult": "Fail",
    "ProcessedAt": "2022-07-20T10:07:43.650Z",
    "RecordId":“dfdsf-3242-sdfds”,
    "ApiResponse": {
        "errors": {
            "Entries": [
                {
                    "code": "-1",
                    "internalErrorMessage": “”,
                    "links": {
                        "about": “”,
                        "help”:””                        },
                    "detail": {
                        "Entries": [
                            {
            "23505: duplicate key value violates "
                            }
                        ]
                    },
                    "source": “test Service",
                    "incidentId": {},
                    "status": “500”
                }
            ]
        }
    } }

任何人都可以通过建议一些 nuget 包或通过一些手动过程来帮助我实现这一点，尝试了很多仍然无法实现这一点，抱歉，如果这是一个重复的问题。

您应该使用ToJsonPretty扩展方法从文档对象中获取漂亮的 JSON。

Document document = Document.FromAttributeMap(...); 
string jsonString = document.ToJsonPretty(); <--- This is what you need

对于此消息，您需要Amazon.DynamoDBv2.DocumentModel命名空间。
