样本代码

以下样本根据您的自定义视觉训练来预测和分类给定的图像. 要了解更多的情况,请参考 Azure 定制视觉服务文件。 。 。 .

const { PredictionAPIClient } = require("@azure/cognitiveservices-customvision-prediction");
const { ApiKeyCredentials } = require("@azure/ms-rest-js");

async function main() {
  const customVisionPredictionKey =
    process.env["customVisionPredictionKey"] || "<customVisionPredictionKey>";
  const customVisionPredictionEndPoint =
    process.env["customVisionPredictionEndPoint"] ||
    "<customVisionPredictionEndPoint>";
  const projectId = process.env["projectId"] || "<projectId>";

  const credentials = new ApiKeyCredentials({ inHeader: {"Prediction-key": customVisionPredictionKey } });
  const client = new PredictionAPIClient(credentials, customVisionPredictionEndPoint);

  const imageURL =
    "https://www.atlantatrails.com/wp-content/uploads/2019/02/north-georgia-waterfalls-1024x683.jpg";

  client
    .classifyImageUrl(projectId, "Iteration1", { url: imageURL })
    .then(result => {
      console.log("The result is: ");
      console.log(result);
    })
    .catch(err => {
      console.log("An error occurred:");
      console.error(err);
    });
}

main();
