Power BI API POST 数据源错误 DMTS_InvalidEncryptionAlgorithmError

Question

我正在尝试使用 Microsoft Power BI API 在网关上创建新数据源 https://docs.microsoft.com/en-us/rest/api/power-bi/gateways/createdatasource。为了测试，我正在尝试使用基本身份验证创建到 Azure Sql 数据库 的连接。我可以使用 Power BI 在线 GUI 添加数据源而没有问题，但是每当我尝试使用 API 时，我都会收到 400 - DMTS_InvalidEncryptionAlgorithmError.

关键字段是body中的encryptionAlgorithm，但如API文档中所述，云应该是"None"数据源。

我也尝试过使用 "RSA-OAEP"，但这给了我 400 - DM_GWPipeline_UnknownError。

我目前正在使用 Postman，但我也尝试使用 NodeJS 复制相同的请求并得到相同的结果。

任何关于解决方案的提示都会非常有帮助。

Headers

content-type: application/json,

Body

{
"datasourceType": "Sql",
"connectionDetails": "{\"server\":\"servername.database.windows.net\",\"database\":\"dbname\"}",
"credentialDetails": {
    "credentialType": "Basic",
    "credentials": "{\"credentialData\":[{\"name\":\"username\", \"value\":\"myusername\"},{\"name\":\"password\", \"value\":\"mypwd\"}]}",
    "encryptedConnection": "Encrypted",
    "encryptionAlgorithm": "None",
    "privacyLevel": "None"
},
"datasourceName": "new-datasource-name"
}

使用 "None" 时的错误消息 - HTTP 400

{
"error": {
    "code": "DMTS_InvalidEncryptionAlgorithmError",
    "pbi.error": {
        "code": "DMTS_InvalidEncryptionAlgorithmError",
        "parameters": {},
        "details": [],
        "exceptionCulprit": 1
    }
}
}

使用 "RSA-OAEP" 时的错误消息 - HTTP 400

    "code": "DM_GWPipeline_UnknownError",

                    "value": "The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters. "
                }
            },
            {

Answer 1

我认为您需要在加载时加密您的凭据 - 文档中没有说得很清楚。您不能只上传免费文本。

对安全有意义！

Answer 2

为了完整起见，这里是您可以用来加密凭据的节点代码。使用库 node-rsa

const nodeRSA  = require("node-rsa");

const credentials = '{\"credentialData\":[{\"name\":\"username\", \"value\":\"myusername\"},{\"name\":\"password\", \"value\":\"mypwd\"}]}';

const exponentString = 'AQAB';
const modulusString = 'rasdfsafsdfsadfsdafsdferasdasgfasgsfgdfgsdfgdsfgrgsrareasgasgasfasfasdfasdfsadfsadfgsadfsadfasfasdfsadfsdafasdfrgrhe4t345tge5g54g5gegdrg5tg45efgdfg5t=';

const key = new nodeRSA();

const modulus = new Buffer(modulusString, 'base64');
const exponent = new Buffer(exponentString, 'base64');

const pubKey = key.importKey({ n: modulus, e: exponent }, 'components-public');

const encrypted = pubKey.encrypt(credentials, 'base64');

console.log(encrypted)
