}

这里我只希望第一次处理2个事务，而不是接下来的事务。所以我使用了getQueryResultWithPagination方法，但它不能在单个对象上工作。所以我创建了一个CouchDB的视图.

"views": {
"tx-view": {
"map": "function (doc) {if(doc.transactions.length > 0) {          emit(doc.transactions); }}"
},
"tx-view-2": {
"map": "function (doc) { if(doc.transactions.length > 0) {      doc.transactions.forEach(function (tag) {    emit(doc.user_id, tag);  });}}"
}
},

我可以将此视图添加到chaincode查询方法中并为其创建一个事务吗?我该如何解决这个问题?
