Watson 视觉识别 API C# 授权
Watson Visual Recognition API C# Authorisation
尝试让 Watson Visual Recognition 使用 C#,但在尝试通过 API 对图像进行分类时出现未经授权的错误。我使用的凭据是 "Auto-generated service credentials".
我收到的错误是:
ServiceResponseException:API 查询失败,状态码未授权:未授权
这是我的代码:
class Program
{
static void Main(string[] args)
{
string apiKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
string versionDate = "2018-03-19";
string endpoint = "https://gateway.watsonplatform.net/visual-recognition/api";
VisualRecognitionService visualRecognition = new VisualRecognitionService(apiKey, versionDate);
visualRecognition.SetEndpoint(endpoint);
// throws error here
var result = visualRecognition.Classify(url: "https://upload.wikimedia.org/wikipedia/commons/thumb/d/d9/Collage_of_Nine_Dogs.jpg/1023px-Collage_of_Nine_Dogs.jpg");
}
}
此外,如果我能提供更多可能有帮助的信息,请告诉我
好的,在查看 node.js 实施的答案后,我找到了解决方案:
问题是我需要使用 Iam Api 密钥进行身份验证,可以这样做:
class Program
{
static void Main(string[] args)
{
string apiKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
string versionDate = "2018-03-19";
string endpoint = "https://gateway.watsonplatform.net/visual-recognition/api";
VisualRecognitionService visualRecognition = new VisualRecognitionService(apiKey, versionDate);
visualRecognition.SetEndpoint(endpoint);
// updated to include token options with Iam Api Key
TokenOptions options = new TokenOptions
{
IamApiKey = apiKey
};
visualRecognition.SetCredential(options);
// end edit
var result = visualRecognition.Classify(url: "https://upload.wikimedia.org/wikipedia/commons/thumb/d/d9/Collage_of_Nine_Dogs.jpg/1023px-Collage_of_Nine_Dogs.jpg");
}
}
