【问题描述】：

我想访问数据库，但出现此错误。代码如下：

const neo4j = require("neo4j-driver").v1;
const driver = neo4j.driver(
  "bolt://localhost:7687",
  neo4j.auth.basic("neo4j", "1234")    
);
      const session = driver.session();    
app.post("/registro", function(req, res) {  
        var nombre = req.body.nombre;
        var apellidos= req.body.apellidos;
        var email= req.body.email;
        var pass= req.body.pass;
        session.run("MATCH (user:Usuario {email:"+email+"}) RETURN user")
        .then(results => {    
      if (!_.isEmpty(results.records)) {
              console.log("error")
          }
          else {
        console.log("bien")
      }
    })    
    .catch(error => {    
      session.close();
      console.log(error);
      driver.close()    
    })    
});

我得到了这个错误：

【解决方案1】：

您是否在使用带有加密功能的 neo4j？我认为您应该在创建驱动程序时发送基本配置

const driver = neo4j.driver(
  "bolt://localhost:7687",
  neo4j.auth.basic("neo4j", "1234"),
  { encrypted: true }   
);
