GraphQL Apollo错误：未捕获（承诺）

提问于

我'm trying to submit new data to my local graphQL API via button click but I' m收到错误：错误错误：未捕获（在承诺中）：错误：网络错误：http://localhost:4000/graphql的Http失败响应：400错误请求 .

the idea is that when you press the button new data gets submitted

<button type="submit" (click)="onSubmit()" [disabled]="!personForm.valid" id="buttonSubmit" mat-raised-button color="accent"class="floated">Send</button>

onSubmit function calls mutation

onSubmit() 
  {
    let id = 5;
    let vorname = 'user';
    let name =  'name';
    let email =  'testt@hotmail.com';
    let status =  'true';
    let activity =  'Office';

    this.apollo.mutate<CreateUserMutationResponse>({
      mutation: CREATE_USER_MUTATION,
      variables: {
        id: id,
        vorname: vorname,
        name: name,
        email: email,
        status: status,
        activity: activity
      }
    }).subscribe((response) => {

    });

    console.log('submitted');

  }

The mutation in my types.ts looks like this

export const CREATE_USER_MUTATION = gql`
  mutation CreateUserMutation($id: ID!, $vorname: String!, $name: String!, $email: String!, $status: String!, $activity: String) {
    createUser(id: $id,vorname: $vorname, name: $name, email: $email, status: $status, activity: $activity) {
      id
      vorname
      name
      email
      status
      activity
    }
  }
`;

export interface CreateUserMutationResponse {
  createUser: String;
}
javascript typescript graphql apollo

    当我找到你的问题时，我确实遇到了同样的问题 . 关于这个的文档很难得到，但是，this example让我知道如何解决这个问题 . 在我将try catch statement中的突变包围起来后，它对我有用 . 这样的事情我非常肯定会为你解决这个问题：

    onSubmit() {

  [...]

  try {
    this.$apollo.mutate <CreateUserMutationResponse>({
      mutation: CREATE_USER_MUTATION,
      variables: {
        id: id,
        vorname: vorname,
        name: name,
        email: email,
        status: status,
        activity: activity
       }
     }).subscribe((response) => { });
   } catch (e) {
      console.error(e);
   }

  console.log('submitted');

    This page也帮助我首先设置了突变（看起来你已经正确地做了） .
