javascript - 为什么从promise.all中调用我的apolloFetch调用会返回一个空查询？

我正在尝试在Node.js微服务的apolloFetch内使用Promise.all，但始终收到错误消息，查询为空。使用apolloFetch的原因是调用另一个微服务并将其传递给查询数组。有人可以给我指示吗？我的代码如下：

   const uri = "dsc.xxx.yyyy.com/abc/def/graphql";
   const apolloFetch = CreateApolloFetch({uri});
  const QryAllBooks = {
    type: new GraphQLList(BookType),
    args: {},
    resolve() {
        return new Promise((resolve, reject) => {
            let sql = singleLineString`
                  select distinct t.bookid,t.bookname,t.country
                  from books_tbl t
                  where t.ship_status = 'Not Shipped'
              `;
            pool.query(sql, (err, results) => {
                if (err) {
                    reject(err);
                }
                resolve(results);
                const str = JSON.stringify(results);
                const json = JSON.parse(str);
                const promises = [];
                for (let p = 0; p < results.length; p++) {
                    const book_id = json[p].bookid;
                    const query = `mutation updateShipping
                              {updateShipping
                               (id: ${book_id}, input:{
                                  status: "Shipped"
                               })
                               { bookid
                                 bookname }}`;
                    promises.push(query);
                }
                //Below is the Promise.all function with the
                //apolloFetch that calls another graphql endpoint
                //an array of queries
                Promise.all(promises.map(p => apolloFetch({p}))).then((result) => {
                    //this is the problem code^^^^^^^^^^^^^^^^^^^^^
                    resolve();
                    console.log("success!");
                }).catch((e) => {
                    FunctionLogError(29, "Error", e);
                });
            });
        });
    }
};
module.exports = {
    QryAllBooks,
    BookType
};

最佳答案

看来apolloFetch需要query-您正在传递p

更改

Promise.all( promises.map(p=>apolloFetch({p})) )

至

Promise.all( promises.map(query=>apolloFetch({query})) )

您也打电话给解决两次

解决所有错误或成功

const final_results = []
Promise.all(promises.map(query => apolloFetch({
  query,
}))).then((result) => {
  final_results.push(result)
}).catch((e) => {
  final_results.push(e)
}).then(() => {
  resolve(final_results)
});
