Angular graphql在请求中添加回车符

如何解决Angular graphql在请求中添加回车符

似乎graphql正在将回车符添加到我的json请求中。它还添加了_typename，但是我在graphql.module.ts中使用addTypename：false删除了它。如何摆脱回车符？

在graphql.module.ts

export function createApollo(httpLink: HttpLink) {  
  return {    
    link: httpLink.create({uri}),cache: new InMemoryCache({
      addTypename: false
    }),};
}

在home.component.ts

import { Component,OnInit } from "@angular/core";
import { Apollo } from "apollo-angular";
import gql from "graphql-tag";

@Component({
  selector: "app-home",templateUrl: "./home.component.html",styleUrls: ["./home.component.css"]
})
export class HomeComponent implements OnInit {
  statemind: any[];
  loading = true;
  error: any;

  constructor(private apollo: Apollo) {}

  ngOnInit() {
    this.apollo
      .query<any>({
        query: gql `{statemind{issue{person{firstname lastname}}}}`
      })
      .subscribe(
        ({ data,loading }) => {
          this.statemind = data && data.statemind;
          this.loading = loading;
        },error => {
          this.loading = false;
          this.error = error;
        }
      );
  }
}

我明白了

error: "Bad Request"
message: "JSON parse error: Cannot deserialize instance of `java.lang.String` out of START_OBJECT token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.lang.String` out of START_OBJECT token↵ at [Source: (PushbackInputStream); line: 1,column: 35]"
path: "/v1/graphql"
status: 400

如果我在Chrome的开发人员工具中的“网络”下查看，似乎在查询中添加了回车符：

operationName: null,variables: {},…}
operationName: null
query: "{↵  statemind {↵    issue {↵      person {↵        firstname↵        lastname↵      }↵    }↵  }↵}↵"
variables: {}
