Question

这里第一次当我调用updateRegistery时，只有auctionItem被更新为“Selling”，并且在超时1分钟后再次调用updateRegistery，这次不会更新“auctionItem”或“auction”。没有.catch（）函数被调用，这意味着所有的promise都被成功解析。请告诉我哪里出错了？

没有模特很难看到。您还有非确定性代码（new Date（）。getTime（）），这可能意味着您的同事会对结果达成一致（不确定您在设置中有多少同伴）。

您可以尝试使用此链来查看两个注册表是否都在更新。

return getAssetRegistry( NS + '.EnglishAuctionItem' )
  .then(function ( englishAuctionItemRegistery ) {
     console.log("EnglishAuctionItem Updated Successfully.!");
     return englishAuctionItemRegistery.update( auctionItem ) ;
  })
  .then function() {
   return getAssetRegistry( NS + '.EnglishAuction' )
     .then(function ( englishAuctionRegistery ) {
           console.log("EnglishAuction Updated Successfully.!");
           return englishAuctionRegistery.update(auction);
      })
    .catch(function( error ) {
       console.log("Error", error);
  });
