请求说明
http请求方式:POST
https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN
请求示例
{
"button":[
{
"type":"click",
"name":"今日歌曲",
"key":"V1001_TODAY_MUSIC"
},
{
"type":"click",
"name":"歌手简介",
"key":"V1001_TODAY_SINGER"
},
{
"name":"菜单",
"sub_button":[
{
"type":"click",
"name":"hello word",
"key":"V1001_HELLO_WORLD"
},
{
"type":"click",
"name":"赞一下我们",
"key":"V1001_GOOD"
}]
}]
}
我的代码如下:
$xjson = ' { "button":[ { "type":"click", "name":"todaymusic", "key":"V1001_TODAY_MUSIC" }, { "type":"click", "name":"singer", "key":"V1001_TODAY_SINGER" }, { "name":"menu", "sub_button":[ { "type":"click", "name":"hello word", "key":"V1001_HELLO_WORLD" }, { "type":"click", "name":"best", "key":"V1001_GOOD" }] }] }';$url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=******";$context = json_decode($xjson,true);$data = http_build_query($context);$result = vpost($url,$data);var_dump($result);function vpost($url,$data){ // 模拟提交数据函数 $curl = curl_init(); // 启动一个CURL会话 curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); // 对认证证书来源的检查 curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE); // 从证书中检查SSL加密算法是否存在 curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)'); // 模拟用户使用的浏览器 // curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转 // curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer curl_setopt($curl, CURLOPT_POST, 1); // 发送一个常规的Post请求 curl_setopt($curl, CURLOPT_POSTFIELDS, $data); // Post提交的数据包 curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循环 curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回 $tmpInfo = curl_exec($curl); // 执行操作 if (curl_errno($curl)) { echo 'Errno'.curl_error($curl);//捕抓异常 } curl_close($curl); // 关闭CURL会话 return $tmpInfo; // 返回数据}
一直不成功,提示"{"errcode":40016,"errmsg":"invalid button size"}"
想问下,
1. 这个代码本身有问题吗?
2. 是不是本机的环境需要支持https?
回复讨论(解决方案)
你的程序环境没问题,问题在于POST的数据格式,没接触过,所以不能提供什么有用的信息,这个错误说明你的json中多了或少了按钮,建议你可以尝试增加或减少button元素看看
这个提示应该很明晰了
"{"errcode":40016,"errmsg":"invalid button size"}"
不合法的按钮个数
从提示看不像是curl的错误,像是api的返回,如果这样的话说明发过去了,只是数据格式不对
但这就有另一个疑问,https能直接发么?
请问楼主解决了么?我也报同样错误。菜单个数应该是没有问题的
这个好弄,我是北京程序员之家的技术,具体联系我qq吧:651732826
你好!我也遇到这个问题了,请问您解决了吗?能指点一下吗?谢谢!
唉,我也遇上这个问题了
我也是。。。
me too!!!

这段代码亲测可用。记得导入commons-httpclient-3.0.1.jar这个包哦
PHP代码找到了。

我开始是用php写的,可一直解决不了,后来换成linux下直接用curl可以解决,但是要注意中文编码。
我是这么做的: 把json string 写好,然后得到一个没有空格和回车的版本,然后在linux下用curl, 代码如下:
curl -d '{ "button":[ { "name":"健康查询", "sub_button":[ { ".....' https://api.weixin.qq.com/cgi-bin/menu/create?access_token=xxxx
注意-d后面的是单引号,否则就是invlide button size 40016.
hoping this can help.
我已经解决:

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
