Question

我能够console.log POST方法的响应。但是我想将此响应存储在变量中，以在代码中进一步使用它。请帮忙。

post方法调用发送一个对象作为响应。

student.ts（“学生”是一个类，与从发帖请求中接收的对象相同。）

export class Student {
ID : number;
firstName : string;
}

component.ts（在提交表单时调用submit方法。this.student提供未定义的输出）

public student : Student[];

onSubmit() {
    this._studentService.addData(this.addStudentForm.value)
      .subscribe( response => console.log("respnse", response),
        );
    console.log(this.student);
  }

service.ts

addData(studentData) : Observable<any> {
    return this.http.post<any>(this._url, studentData);
  }

当我尝试将响应存储到变量中时，我得到的输出未定义。如何将响应存储在变量中？

Answer 1

您应该只在订阅中添加this.student = response;：

this._studentService.addData(this.addStudentForm.value).subscribe( response => {
    console.log("respnse", response);
    this.student = response;
});

但是，如果您想对student进行操作，则应在next的订阅回调中执行此操作：

this._studentService.addData(this.addStudentForm.value).subscribe( response => {
    console.log("respnse", response);
    this.student = response;
    console.log(this.student) <- THIS WILL WORK - STUDENT IS NOT UNDEFINED
    // HERE ARE YOUR METHODS WHICH ARE USING STUDENT
});

在订阅之后，此console.log仍将是未定义的，因为此代码将在订阅结束前执行，因此student暂时为undefinded。

尝试：

other_pipes = [pipe for pipe in nlp.pipe_names if pipe != "ner"]
with nlp.disable_pipes(*other_pipes):
    optimizer = nlp.begin_training()
    for i in range(10):
         random.shuffle(train_data)
         for text, annotations in train_data:
             nlp.update([text], [annotations], sgd=optimizer)```

Error Traceback:
