微信开发–php curl上传素材文件到微信服务器

内容纲要

最近在研究微信公众平台开发,感觉还是蛮有意思的,今天项目中需要上传语音文件到微信服务器,然后再发送给用户的功能.网上有很多这方面的代码,用了很多个版本都不能实现上传.下面是网上的版本:

$type = "voice";
$filepath = dirname(__FILE__)."\amr\sdya.amr";
$filedata = array("media"  => "@".$filepath);
$access_token = 'aaaaaaa';
$url = "http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token=$access_token&type=$type";
$result = wx_upload_media($url, $filedata);
var_dump($result);

function wx_upload_media($url, $data = null){
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    if (!empty($data)){
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    }
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($curl);
    curl_close($curl);
    return $output;
}

$type = "voice";

$filepath = dirname(__FILE__)."\amr\sdya.amr";

$filedata = array("media" => "@".$filepath);

$access_token = 'aaaaaaa';

$url = "http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token=$access_token&type=$type";

$result = wx_upload_media($url, $filedata);

var_dump($result);

function wx_upload_media($url, $data = null){

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, $url);

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);

curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);

if (!empty($data)){

curl_setopt($curl, CURLOPT_POST, 1);

curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

}

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

$output = curl_exec($curl);

curl_close($curl);

return $output;

}

经过种种尝试各种折腾发现然并卵!!!!!

后面一查手册,小伙伴们都惊呆了!!!

PHP 5.5另外引入了CURL_SAFE_UPLOAD选项，可以强制PHP的cURL模块拒绝旧的@语法，仅接受CURLFile式的文件。5.5的默认值为false，5.6的默认值为true。

于是乎,加上这个参数试了一下,very good,代码如下

$type = "voice";
$filepath = dirname(__FILE__)."\amr\sdya.amr";
$filedata = array("media"  => "@".$filepath);
$access_token = 'aaaa';
$url = "http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token=$access_token&type=$type";
$result = wx_upload_media($url, $filedata);
var_dump($result);

function wx_upload_media($url, $data = null){
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($curl, CURLOPT_SAFE_UPLOAD, FALSE);
    if (!empty($data)){
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    }
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($curl);
    curl_close($curl);
    return $output;
}
