我有一个与数据库有关的问题。我目前正在使用 Gupshup 机器人编程。这里和这里有两种不同的数据持久化模式。在高级数据持久化中,记录了以下代码将数据放入数据库:
function MessageHandler(context, event) {
if(event.message=='update bug - 1452') {
jiraUpdate(context);
}
}
function jiraUpdate(context){
//connect to Jira and check for latest update and values
if(true){
context.simpledb.doPut("1452" ,"{\"status\":\"QA pending\",\"lastUpdated\":\"06\/05\/2016\",\"userName\":\"John\",\"comment\":\"Dependent on builds team to provide right build\"}");
} else{
context.sendResponse('No new updates');
}
}
function DbPutHandler(context, event) {
context.sendResponse("New update in the bug, type in the bug id to see the update");
}
如果我只想更改表中键值为 1452 的行的一列(例如状态或上次更新),我无法执行此操作。怎么可能呢?
我使用了以下代码:
function MessageHandler(context, event) {
// var nlpToken = "xxxxxxxxxxxxxxxxxxxxxxx";//Your API.ai token
// context.sendResponse(JSON.stringify(event));
if(event.message=='deposit') {
context.sendResponse("Enter the amount to be deposited");
}
if(event.message=="1000") {
jiraUpdate(context);
}
if(event.message== "show"){
context.simpledb.doGet("1452");
}
}
function HttpResponseHandler(context, event) {
var dateJson = JSON.parse(event.getresp);
var date = dateJson.date;
context.sendResponse("Today's date is : "+date+":-)");
}
function jiraUpdate(context){
//connect to Jira and check for latest update and values
if(true){
context.simpledb.doPut("aaa" ,"{\"account_number\":\"90400\",\"balance\":\"5800\"}");
} else{
context.sendResponse('No new updates');
}
}
/** Functions declared below are required **/
function EventHandler(context, event) {
if (!context.simpledb.botleveldata.numinstance)
context.simpledb.botleveldata.numinstance = 0;
numinstances = parseInt(context.simpledb.botleveldata.numinstance) + 1;
context.simpledb.botleveldata.numinstance = numinstances;
context.sendResponse("Thanks for adding me. You are:" + numinstances);
}
function DbGetHandler(context, event) {
var bugObj = JSON.parse(event.dbval);
var bal = bugObj.balance;
var acc = bugObj.account_number;
context.sendResponse(bal);
var a = parseInt (bal,10);
var b = a +1000;
var num = b.toString();
context.simpledb.doPut.aaa.balance = num;
}
function DbPutHandler(context, event) {
context.sendResponse("testdbput keyword was last put by:" + event.dbval);
}
