这个问题的原因是使用了Apollo useLazyQuery hook进行查询时，组件可能会因为某种原因多次重新渲染。每次渲染时，onCompleted回调都会被触发一次。为了避免出现这种情况，我们可以使用useRef hook来跟踪每次组件渲染后的onCompleted回调函数，只有在回调函数改变时才重新执行它。

示例代码：

import React, { useEffect, useRef } from 'react';
import { useLazyQuery } from '@apollo/react-hooks';
import { QUERY } from './queries';

const MyComponent = () => {
  const [executeQuery, { data }] = useLazyQuery(QUERY);
  const onCompletedRef = useRef();
  
  // Store the onCompleted callback in a ref
  useEffect(() => {
    onCompletedRef.current = () => {
      // Perform actions after query completes
    };
  }, []);
  
  // Call the stored onCompleted callback
  useEffect(() => {
    if (data && onCompletedRef.current) {
      onCompletedRef.current();
    }
  }, [data]);

  return (
    

      {data && 
{data}
}
       executeQuery()}>Execute Query
    
  );
};

export default MyComponent;
