With the popularity of WeChat mini programs, more and more companies have begun to pay attention to the development and promotion of WeChat mini programs. Among them, the live broadcast function is a very popular function. This article will focus on how to use PHP to develop the live broadcast function of the WeChat applet and provide specific code examples.
1. Preparation work
Before developing the live broadcast function of the WeChat applet, some preparation work needs to be done first.
Configure the following in the WeChat Mini Program background:
(1) Activate the WeChat Mini Program live broadcast function
In "Settings"->"Development Settings"->"Live Broadcast", turn on the WeChat mini program live broadcast function and perform offline subject authentication.
(2) Obtain the mini program ID and key
Obtain the mini program ID and key in the mini program background, enable the WeChat payment function, and obtain the merchant number and key.
Before proceeding with PHP development, you need to set up a PHP development environment. The specific steps are as follows:
(1) Install the Apache server and PHP parser
Download the Apache server and PHP parser from the Internet and install it according to the prompts.
(2) Configure PHP in the Apache server
In the Apache server configuration file httpd.conf file, add the following code:
LoadModule php5_module "c:/php/ php5apache2_4.dll"
AddHandler application/x-httpd-php .php
PHPIniDir "C:/php"
Among them, php5_module is the module name of the PHP parser, and php5apache2_4.dll is the PHP parser The DLL file name of the parser, PHPIniDir is the configuration file path of the PHP parser.
(3) Test whether the PHP development environment is normal
Create a PHP file in the root directory of the Apache server with the content:
phpinfo( );
?>
Name the file phpinfo.php and access the file in the browser. If the PHP version information can be displayed, the PHP development environment is configured successfully.
2. Develop WeChat mini program live broadcast function
Before calling the WeChat mini program live broadcast interface, you need to obtain the access_token first. The specific code is as follows:
To create a live broadcast room in the WeChat applet, you need to call the createLiveRoom interface. The specific code is as follows:
'直播间名称', 'cover_img' => '直播间封面图URL', 'startTime' => '开始时间', 'endTime' => '结束时间', 'anchorName' => '主播姓名', 'anchorWechat' => '主播微信号', 'shareImg' => '分享图URL', 'type' => 1, 'closeLike' => 0, 'closeGoods' => 0, 'closeComment' => 0, 'sendRecordStatus' => 0, ); $data = json_encode($data); $res = json_decode(http_request($url, $data), true); function http_request($url, $data){ $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); $res = curl_exec($curl); curl_close($curl); return $res; } ?>
Among them, name is the name of the live broadcast room, cover_img is the URL of the cover image of the live broadcast room, startTime and endTime are the start time and end time of the live broadcast room, anchorName is the name of the anchor, and anchorWechat is the anchor's WeChat ID. shareImg is the sharing image URL, type is 1 indicating live broadcast, closeLike, closeGoods, closeComment, and sendRecordStatus are parameters for whether to turn off likes, goods, comments, and playback respectively.
Updating the live room in the WeChat applet requires calling the modifyLiveRoom interface. The specific code is as follows:
'直播间ID', 'name' => '直播间名称', 'cover_img' => '直播间封面图URL', 'anchorName' => '主播姓名', 'anchorWechat' => '主播微信号', 'shareImg' => '分享图URL', ); $data = json_encode($data); $res = json_decode(http_request($url, $data), true); function http_request($url, $data){ $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); $res = curl_exec($curl); curl_close($curl); return $res; } ?>
Among them, id is the live broadcast room ID, name, cover_img, anchorName, anchorWechat, shareImg are the same as the interface for creating the live broadcast room.
To start live broadcast in the WeChat applet, you need to call the startLive interface. The specific code is as follows:
'直播间ID', 'name' => '直播间名称', 'coverImg' => '直播间封面图URL', 'startTime' => '开始时间', 'endTime' => '结束时间', 'anchorName' => '主播姓名', 'anchorWechat' => '主播微信号', 'shareImg' => '分享图URL', ); $data = json_encode($data); $res = json_decode(http_request($url, $data), true); function http_request($url, $data){ $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); $res = curl_exec($curl); curl_close($curl); return $res; } ?>
Among them, roomId is the live broadcast room ID, and name, coverImg, anchorName, anchorWechat, and shareImg are the same as the interface for creating a live broadcast room.
To end the live broadcast in the WeChat applet, you need to call the finishLive interface. The specific code is as follows:
'直播间ID', ); $data = json_encode($data); $res = json_decode(http_request($url, $data), true); function http_request($url, $data){ $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); $res = curl_exec($curl); curl_close($curl); return $res; } ?>
Among them, roomId is the live broadcast room ID.
3. Summary
The above is the full content and specific code examples of using PHP to develop the live broadcast function of WeChat mini program. When developing, you need to pay attention to the configuration of the mini program backend and the establishment of the PHP development environment. At the same time, when using the live broadcast interface, you need to pass in the correct parameters and data format.
The live broadcast function is a very important and practical function in the WeChat mini program, which can help enterprises achieve online live broadcast, marketing and promotion and other purposes. I hope this article can help developers who are developing the live broadcast function of WeChat mini programs.
