1. Introduction

The WeChat public platform service account and subscription account that successfully applied for internal beta qualification before have the function of customizing menus. Developers can use this function to add a custom menu to the bottom of the public account's conversation interface. Users can click on the options in the menu to bring up the corresponding reply information or web link. The customized menu interface will provide more possibilities for the information display space of public accounts. This article will do a simple development application for custom menus for readers’ reference.

2. Official description

After developers obtain the usage credentials, they can use the credentials to create, query, and delete the custom menu of the public account. The custom menu interface can implement the following types of buttons:

click (click event):

After the user clicks the click type button, the WeChat server will push the click event to the developer through the message interface (event type), and bring the key value filled in by the developer in the button. The developer can reply to the message through the customized key value.

view (visit web page):

After the user clicks the view type button, it will jump directly to the URL specified by the developer.

After creating a custom menu, it will take 24 hours for the WeChat client to display it due to cache on the WeChat client. It is recommended that when testing, you can try to unfollow the public account and follow it again, and you can see the effect after creation.

3. Obtain usage voucher

3.1 Get appid and appsecret

Find the appid and appsecret in WeChat Public Platform > Advanced Functions > Development Mode.

3.2 Use appid and appsecret to request access_token from the WeChat credential acquisition interface

Request address: https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET

Request parameter description:

grant_type: Get access_token and fill in client_credential

appid: unique credential for third-party users

secret: The unique credential key for third-party users, namely appsecret

Return instructions:

Correct Json return result:

{"access_token":"ACCESS_TOKEN","expires_in":7200}

Return parameter description:

access_token: Obtained certificate

expires_in: voucher validity time, unit: seconds

3.3 Specific implementation

a. Print out the format

<?php

$APPID="wxdxxxxxxxxxxxxxxx";
$APPSECRET="96xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

$TOKEN_URL="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$APPID."&secret=".$APPSECRET;

$json=file_get_contents($TOKEN_URL);
$result=json_decode($json,true);
print_r($result);

?>

The results are as follows:

b. Get access_token

<?php

$APPID="wxdxxxxxxxxxxxxxxx";
$APPSECRET="96xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

$TOKEN_URL="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$APPID."&secret=".$APPSECRET;

$json=file_get_contents($TOKEN_URL);
$result=json_decode($json,true);

$ACC_TOKEN=$result[&#39;access_token&#39;];

echo $ACC_TOKEN;

?>

Note: access_token corresponds to the public account and is a globally unique ticket. Repeated acquisition will cause the last access_token to become invalid.

4. Create menu

           "name":"天气查询",
           "key":"tianQi"
        },
        {
           "type":"click",
           "name":"公交查询",
           "key":"gongJiao"
        },
        {
