The image server is the Sohu cloud Platform. On the Sohu cloud platform has the code package, downloads down, puts in the Yii frame Vendor.yii2.0 Import a third-party library, it's simple, write a autoload file, and then include the AutoLoad file in the portal script Index.php. Specific to this cloud platform library, as long as the code contains the AutoLoad file is Good.Brief introduction of the implementation of the Sohu ptz, the user will have a corresponding domain name, and then choose to build some buckets, file upload download is carried out in this bucket. function calls are clearly described in the documentation provided by the Gimbal. This is no longer introduced Here. At the same time I only from the PHP section to introduce, regardless of the front-end Section.Controller section<pre><pre>class extends controller{ publicfunction actionupload () { //return Imgupdate::uploadtoscs ($_files); return Imgupdate::uploadtolocal ($_files); }}</pre></pre>View CodeThe following is a service that encapsulates an image upload.<pre><pre></pre></pre><pre><?PHP/** * Created by Phpstorm. * User:changshuiwang * DATE:2016/8/2 * time:17:51*/namespace common\service; useyii; usesohucs\scs\scsclient; useYii\base\Exception; useyii\web\uploadedfile;classimgupdate{Constscs_access_key= ' xxxxxxx '; Constscs_secret_key= ' xxxxxxx '; ConstHost= ' xxxxxx '; public Static $type=Array( ' Image/jpeg ', ' image/png ', ' image/jpg ' ); public Static $ext=Array( ' JPEG ', ' png ', ' jpg ' ); /** * @param $file * @return String returns a JSON response*/ public Static functionUploadtoscs ($file,$bucket= ' focus-img ') { Try{ $filename=$file[' file '] [' name ']; $tmp _name=$file[' file '] [' Tmp_name ']; //Check file legitimacySelf::checkimgext ($filename,$tmp _name); if($file[' file ']){ $ext=self::getextension ($filename); $client= Scsclient::factory (Array( ' Key ' = self::scs_access_key, ' secret ' + self::scs_secret_key, ' region ' =&gt ; "bjcnc" )); //determine if a bucket exists if(!$client->doesbucketexist ($bucket)){ $result=$client->createbucket (Array( ' Buckets ' =$bucket, ' locationconstraint ' = self::HOST)); $client->waituntilbucketexists (Array(' Buckets ' =$bucket)); } $randName=uniqid().‘.‘.$ext; $filename= "dianping/photos/".Date(' Ym ', time())." /".$randName;//the file name after uploading $pathToFile=$tmp _name;//temporary file name generated by PHP after image upload $result=$client->putobject (Array( ' Buckets ' =$bucket, ' Key ' =$filename, ' Body ' =fopen($pathToFile, ' r+ '), )); returnJson_encode (Array( ' Status ' = ' success ', ' msg ' =>self::host.

Yii inherits the rules () method for the subclass inheriting the model, and the rules () method can also judge the file type, and the underlying of Yii is verified by Finfo_open Way.yii2.0, the single image uploaded to the Sohu ptz and the picture uploaded to the Computer.
