The PHP yii framework uses MongoDB

1. Installation

Run

php composer.phar require --prefer-dist yiisoft/yii2-mongodb

or add

"yiisoft/yii2-mongodb": "~2.0.0"

To the Require section of your Composer.json.

2. Configuration

Main.php added.

return [ //.... ' components ' = [ ' mongodb ' + = ' class ' = ' \yii\mongodb\connection ', ' dsn ' = ' + ' mong Odb://developer:[email Protected]:27017/mydatabase ',],],];

For example:

' MongoDB ' = [
' Class ' = ' \yii\mongodb\connection ',
' DSN ' = ' mongodb://127.0.0.1:27017/local ',
],

3, the entity class writing

chatmsg.php

<?php

namespace Common\models;

Use Yii;
Use Yii\behaviors\timestampbehavior;

Class Chatmsg extends \yii\mongodb\file\activerecord
{
/*public static function Find ()
{
Return Parent::find ()->where ([' deleted ' = false]);
}*/

public static function Find ()
//{
Use Customerquery instead of the default Activequery
return new Customerquery (Get_called_class ());
//}
Public Function attributes ()
{
Return Array_merge (
Parent::attributes (),
[
' Content ',
' MessageId ',
' From ',
' To ',
' Conversationid ',
' Timestamp ',
' ImageUrl ',
' ImageSize ',
' ImageWidth ',
' ImageHeight ',
' Type ']
);
}

}

Use Andwhere ()/orwhere () to apply the default condition
SELECT from Customer WHERE ' deleted ' =:d eleted and age>30
$customers = Chatmsg::find ()->andwhere (' age>30 ')->all ();

Use where () to ignore the default condition
SELECT from Customer WHERE age>30
$customers = Chatmsg::find ()->where (' age>30 ')->all ();

4. Controller Writing

<?php
namespace Frontend\controllers;
Use Common\helper\myhttpbasicauth;
Use Common\helper\utilhelper;
Use common\models\chatmsg;
Use yii\filters\cors;
Use Yii\helpers\arrayhelper;
Use yii\web\badrequesthttpexception;
Use Yii\web\controller;
Use Yii\filters\auth\httpbasicauth;
Use yii\caching\dbdependency;
Use Yii\mongodb\query;

Class Chatcontroller extends Controller
{
Public $enableCsrfValidation = false;
Public Function Behaviors ()
{

$behaviors = Parent::behaviors ();
$behaviors [' authenticator '] = [
' Class ' = Myhttpbasicauth::classname (),
' Except ' =>[' createmessage ', ' getmessages '],
];

$behaviors = Arrayhelper::merge ([
[
' Class ' = Cors::classname (),
],
], $behaviors);

return $behaviors;
}

Public Function actiongetmessages () {
$query = new Query;
Compose the query
$query->select ([' content ', ' messageId ', ' from ', ' to ', ' Conversationid ', ' timestamp ', ' imageUrl ', ' imageSize ', ' ImageWidth ', ' imageheight ', ' type '])
->from (' Aaa.files ')
->limit (10);
Execute the query
$rows = $query->all ();
$rows = Chatmsg::find ()->asarray ()->all ();
$rt [' e '] = 0;
$rt [' datas '] = $rows;
Return Json_encode ($RT);

}

Public Function Actioncreatemessage () {
$request = \yii:: $app->request;
if (! $request->ispost) {
return Json_encode ([' E ' =>1001, ' m ' = = ' wrong request type ']);
}

if (!isset ($_post[' data ')) {
return Json_encode ([' E ' =>1002, ' m ' = ' = ' missing necessary parameters ']);
}

$rowJson = $_post[' data '];
$reqData = Json_decode ($rowJson, true);

$messageId = 0;
if (isset ($reqData [' MessageID '])) {
$messageId = $reqData [' MessageID '];
}
$from = 0;
if (isset ($reqData [')]) {
$from = intval ($reqData [' from ']);
}
$to = 0;
if (isset ($reqData [')]) {
$to = intval ($reqData [' to ']);
}
$imageWidth = 0;
if (isset ($reqData [' imagewidth '])) {
$imageWidth = intval ($reqData [' imagewidth ']);
}
$imageHeight = 0;
if (isset ($reqData [' imageheight '])) {
$imageHeight = intval ($reqData [' imageheight ']);
}
$imageSize = 0;
if (isset ($reqData [' imagesize '])) {
$imageSize = intval ($reqData [' imagesize ']);
}

$conversationId = 0;
if (Isset ($reqData [' Conversationid '])) {
$conversationId = $reqData [' Conversationid '];
}
$timestamp = 0;
if (Isset ($reqData [' timestamp '])) {
$timestamp = Intval ($reqData [' timestamp ']);
}
$type = 0;
if (Isset ($reqData [' type '])) {
$type = Intval ($reqData [' type ']);
}
$content = ";
if (Isset ($reqData [' content ')]) {
$content = $reqData [' content '];
}
$IMAGEURL = ";
if (Isset ($reqData [' ImageUrl '])) {
$IMAGEURL = $reqData [' ImageUrl '];
}

$msg = new Chatmsg ();
$msg->imageurl = $IMAGEURL;
$msg->imagewidth = $imageWidth;
$msg->imageheight = $imageHeight;
$msg->imagesize = $imageSize;
$msg->content = $content;
$msg->type = $type;
$msg->timestamp = $timestamp;
$msg->conversationid = $conversationId;
$msg->to = $to;
$msg->from = $from;
$msg->messageid = $messageId;

$msg->save ();
if (! $msg->save ()) {
return Json_encode ([' E ' =>1004]);
}

return Json_encode ([' E ' =>0, ' m ' = ' + ' Add success! ‘]);

}
}
