我正在尝试使用 Microsoft Power BI API 在网关https://docs.microsoft.com/en-us/rest/api/power-bi/gateways/createdatasource上创建新数据源。为了测试,我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毫无问题地添加数据源,但是,每当我尝试使用API时,都会收到400-DMTS_InvalidEncryptionAlgorithmError。
主体中的关键字段为 encryptionAlgorithm ,但正如API文档中所述,对于云数据源,该字段应为“无”。
我也尝试过使用“ RSA-OAEP”,但这给了我400-DM_GWPipeline_UnknownError。
我目前正在与Postman合作,但我也尝试使用NodeJS复制相同的请求,并获得相同的结果。
任何有关解决方案的提示都会很有帮助。

我认为您在加载时需要对凭据进行加密-在文档中没有明确说明。您不能只上传免费文本。
对安全性很有道理!

仅出于完整性考虑,以下是可用于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)
