微信接口开发1--向微信发送请求--获取access_token

//随便放置一个php文件在服务器上.执行该方法--调用模拟get提交---到微信-->获得微信返回的access_token

不建议自己编写模拟get提交方法.

建议直接导入微信框架LaneWeChat 中的curl.lib.php文件

01====================直接使用lanewechat框架中的模拟get提交

getaccess_tokyn.php文件

<?php

02====================单个编写模拟get提交

<?php
define("WECHAT_APPID", 'xxxxxx');
define("WECHAT_APPSECRET", 'xxxxxxxxxxxxxxxxxxxxx');文章来源地址https://www.yii666.com/article/754275.html

//把填写入库的的appid.定义为常量.给url做参数使用

//定义模拟get请求

//开发者工具--文档--进入-->( 开始开发--> 获取接口凭据)--http的请求方式-->get

function http_get($url){网址:yii666.com<

$curl = curl_init(); //启动一个curl回话
curl_setopt($curl,CURLOPT_URL,$url );//,设置当前curl对象的属性,要访问的地址

curl_setopt($curl,CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']);//模拟用户使用的浏览器
curl_setopt($curl,CURLOPT_AUTOREFERER,1);//自动设置referer
curl_setopt($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);//获取的信息以文件的形式返回

$tmpinfo = curl_exec($curl);

if(curl_errno($curl)){
return curl_error($curl);
return FALSE;
}

curl_close($curl);

return $tmpinfo;

}

$_url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.WECHAT_APPID.'&secret='.WECHAT_APPSECRET;

$access_token = http_get($_url);

var_dump($access_token);

01在服务器上--模拟get请求---运行php文件-->向微信发送get请求-->获取微信返回的access_token.时.-->传递appid,appsecret--设置在公众号后台的-->已近存入微信数据库

02微信接收到--从服务器端发送的get请求-->检查库中是否存在给appid和密码--存在就随机生成一个加密 access_token

03 服务器接收到返回access_token-->缓存如文件中(不用不停的请求access_token)--失效后再请求就可以

04 获得access_token后---就可以使用微信接口了--请求微信接口时.带上access_token--微信检查access_token有效--运行请求

模拟post提交 数据

<?php

function imitate_post($url,$data){

$ch = curl_init ();
// print_r($ch); //资源类型

curl_setopt ( $ch, CURLOPT_URL, $url );
curl_setopt ( $ch, CURLOPT_POST, 1 );//正规的HTTP POST
curl_setopt ( $ch, CURLOPT_HEADER, 0 );//设置header头,是否包含header头,(一般不用)
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 ); //returntransfer 返回转换,要求结果为json字符串(或者false)
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );

$return = curl_exec( $ch );
curl_close ( $ch );

//print_r($return);

return $return;文章地址https://www.yii666.com/article/754275.html

}

////////////////////////////////

$url = "http://www.cms.com/post.php";//这里换成你服务器的地址网址:yii666.com

$info = array (
'name' => 'hao' ,
'password' => '123'
);

$json = imitate_post($url ,$info);

//返回的json数据 {"access_token":"asdfaxcd132","expire":7200}
//转换成数组

$arr = json_decode($json,true);
//var_dump($arr);
echo 1;

//模拟post提交数据给微信
//就是curl 1初始化,2设置选项,3执行,4关闭.

===============本地接收测试

<?php
function mylog111($str){
file_put_contents('./mylog.txt',$str); 
}

$data = json_encode($_POST); //获取全部post数据,转化成json,写入txt文件中,很多内容.content加上s

//$data = file_get_contents("php://input");
mylog111($data);
$arr = array('access_token'=>'asdfaxcd132','expire'=>7200);
echo json_encode($arr);

======================模拟get提交.就是 file_get_contents

<?php

function imitate_get($url){

$data = file_get_contents($url);
var_dump($data);

}

$url = 'http://www.cms.com/get.php';

imitate_get($url);

==========get.php
