this.uploadFileMixin(this.file, "/releaseReplyTaskFile").then((res) => { let fileUrl = res; console.log("imageUrl is ", fileUrl); this.fileUrl = fileUrl; this.getSgfInfo(fileUrl); }); var replyPlayer = 1; if (this.replyPlayer == "复盘白方" || this.replyPlayer == 2) { replyPlayer = 2; } var data = { replyPlayer: replyPlayer, sgfUrl: this.fileUrl, totalHead: this.totalHead, };这段代码，想先执行完this.getSgfInfo(fileUrl)再给totalHead赋值

可以将赋值操作放在this.getSgfInfo(fileUrl)的回调函数中，即在获取到sgf信息后再进行赋值操作。可以按照以下方式修改代码：

this.uploadFileMixin(this.file, "/releaseReplyTaskFile").then((res) => { 
  let fileUrl = res; 
  console.log("imageUrl is ", fileUrl); 
  this.fileUrl = fileUrl; 
  this.getSgfInfo(fileUrl, () => {
    var replyPlayer = 1; 
    if (this.replyPlayer == "复盘白方" || this.replyPlayer == 2) { 
      replyPlayer = 2; 
    } 
    this.totalHead = data.totalHead; // 在回调函数中进行赋值操作
  }); 
}); 

getSgfInfo(fileUrl, callback) {
  // 获取sgf信息的代码
  // 获取完成后执行回调函数
  callback();
}

这样就可以保证在获取到sgf信息后再进行赋值操作。
