IBM Watson - 自然语言分类器服务（Java SDK）- deleteClassifier() 方法不删除分类器

Question

我试图在 IBM Watson 平台的自然语言分类器服务中调用 deleteClassifier() 方法，操作完成但没有删除分类器。这是我的代码和输出：

代码：

NaturalLanguageClassifier service = new NaturalLanguageClassifier();
service.setUsernameAndPassword("xxxxxxx", "yyyyyyy");

System.out.println("Before deleting: ");
Classifier classifier;
classifier = service.getClassifier("90e7acx197-nlc-38920").execute();
System.out.println(classifier);

service.deleteClassifier("90e7acx197-nlc-38920");

System.out.println("After deleting: ");
classifier = service.getClassifier("90e7acx197-nlc-38920").execute();
System.out.println(classifier);

输出：

我是不是做错了什么？

Answer 1

需要使用.execute()

调用deleteClassifier

将.execute()添加到

service.deleteClassifier("90e7acx197-nlc-38920");

以下方法将删除您的分类器

service.deleteClassifier("90e7acx197-nlc-38920").execute();
