Question

我试过了

@RunWith(SpringRunner.class)
@SpringBootTest
public class ExampleTest {

@Autowired
private Example example;

   @Test
   public void getTwoTest() {

       assertEquals(new Integer(2), example.getTwo());
   }

}

@TestComponent
public class Example {

   public Integer getTwo(){
       return 2;
   }

}

我遇到的问题是this.propositionService.addProposition(this.proposition) .subscribe(this.addSuccessCallback, this.addFailureCallback);和addSuccessCallback无法访问此对象。我不想使用嵌入式lambda表达式。它使代码更不干净。

Answer 1

您可以bind组件的this上下文回调，如下所示：

this.propositionService.addProposition(this.proposition)
        .subscribe(this.addSuccessCallback.bind(this), this.addFailureCallback.bind(this));

如何将函数变量参数传递给angular 2 http subscribe回调？
