Javascript 第一行完成后，如何开始下一行？

我想从CS:GO GC发送和接收一些信息，用我当前的脚本一次发送所有请求，但我希望在这些请求之间有一些延迟（可能是1000-2000ms），以便每个请求都能通过

最好的方法是，行正在启动，当它获得请求的数据时，第二行正在启动。。。等等

我当前的代码如下（简化了一点）：

我会将回调风格的函数转换为promise风格，并使用

async/await

。同样地，在promise中包装

setTimeout

，并使用它来添加中间的等待

async function requestPlayersProfile(SteamID64) {
  return new Promise((resolve, reject) => {
    csgo.requestPlayersProfile(SteamID64, function(ranking) {
      resolve(ranking);
    });
  });
}

async function wait(ms) {
  return new Promise(resolve => {
    setTimeout(resolve, ms);
  });
}

pool.getConnection(function(err, connection) {
  if (err) throw err;
  connection.query("SELECT * FROM Users WHERE SteamID64 IS NOT NULL", async function(
    err,
    rows,
    fields
  ) {
    connection.release();
    if (err) throw err;
    for(const row of rows) {
      const ranking = await requestPlayersProfile(ow.SteamID64);
      var rankid = ranking.ranking.rank;
      var wins = ranking.ranking.wins;
      var private = ranking.player_level;

      console.log("=================================");
      console.log("SteamID: " + `${row.SteamID64}`);
      console.log("Rank: " + rank);
      console.log("Wins: " + wins);
      console.log("Private Rank: " + private);
      console.log("=================================");

      await wait(1000);
    }
  });
});

当我尝试运行它时，我得到了这个错误：const ranking=await requestPlayersProfile（row.SteamID64）；SyntaxError:await仅在异步函数中有效您需要将其包装为异步函数。添加这个

pool.getConnection（异步函数（err，connection）{

async function requestPlayersProfile(SteamID64) {
  return new Promise((resolve, reject) => {
    csgo.requestPlayersProfile(SteamID64, function(ranking) {
      resolve(ranking);
    });
  });
}

async function wait(ms) {
  return new Promise(resolve => {
    setTimeout(resolve, ms);
  });
}

pool.getConnection(function(err, connection) {
  if (err) throw err;
  connection.query("SELECT * FROM Users WHERE SteamID64 IS NOT NULL", async function(
    err,
    rows,
    fields
  ) {
    connection.release();
    if (err) throw err;
    for(const row of rows) {
      const ranking = await requestPlayersProfile(ow.SteamID64);
      var rankid = ranking.ranking.rank;
      var wins = ranking.ranking.wins;
      var private = ranking.player_level;

      console.log("=================================");
      console.log("SteamID: " + `${row.SteamID64}`);
      console.log("Rank: " + rank);
      console.log("Wins: " + wins);
      console.log("Private Rank: " + private);
      console.log("=================================");

      await wait(1000);
    }
  });
});
