exports.basecjh = (callback) => {
const config = {
user: "sa",
password: "cjh13396943871.",
server: "192.168.2.16", // You can use ‘localhost\\instance‘ to connect to named instance

options: {
enableArithAbort: false,
},
};
(async function() {
try {
let pool = await sqlserver.connect(config);
console.log("trigger");
let result1 = await pool
.request()
// .input("input_parameter", sqlserver.Int, value)
.query("select * from t_apply");
// console.dir(result1)
......
解决
增加一行： config.options.encrypt: false, 即可解决。
exports.basecjh = (callback) => {
const config = {
user: "sa",
password: "cjh13396943871.",
server: "192.168.2.16", // You can use ‘localhost\\instance‘ to connect to named instance
database: "Erp_Proj_DataBase",
options: {
enableArithAbort: false,
encrypt: false,#增加该行
},
......
说明：
相关的说明在文档里只找到了简单的一段描述：
https://github.com/tediousjs/node-mssql#configuration
- Parts of the connection URI should be correctly URL encoded so that the URI can be parsed correctly.
- options.encrypt - A boolean determining whether or not the connection will be encrypted (default:
true).
但是没有找到更加深层次的说明，文档上只是说用以给“connection” 进行编码。 应该不是通信协议层面上的编码，因为设定为false后反而连接成功。 这里编码后反而无法连接，不知道具体原因。可能是远端需要对应的解码？ 有可能是处于安全上的考虑？ 这个问题以后可以在留意以下。
