Wechat upload picture material interface

Official wechat documents , This interface's media The explanation is a bit confusing （ It doesn't work , This is to explain what is contained in the file information , No special treatment is required ）

Search for information , Write test code and keep trying , There are two main implementation methods ：

1. Method 1: direct use curl, It is mainly used to test how interface parameters are set , Whether the wechat interface can be adjusted ：

$pathName = realpath('./111.png');

		$url = "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=ACCESSTOKEN&type=image";
		$data = array(
			'media' => new CURLFile($pathName, 'image/png', '111.png')
		);
		$description = array(
			'title' => '111.png',
			'introduction' =>  '111.png',
		);
		$data['description'] = urldecode(json_encode($description));
		// $data = http_build_query($data);// Upload files using curlfile Out of commission http_build_query Handle 

		$ch = curl_init();
		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
		@curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
		curl_setopt($ch, CURLOPT_HEADER, 1);
		@curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
		curl_setopt($ch, CURLOPT_POST, 1);
		curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
		curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
		curl_setopt($ch, CURLOPT_SSLVERSION, 1);
		curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0.1) Gecko/20100101 Firefox/9.0.1');
		$data = curl_exec($ch);
		$status = curl_getinfo($ch);
		$errno = curl_errno($ch);
		curl_close($ch);
		var_dump($data);

  It should be noted that according to php Version select the way to upload files , Please refer to the official website （ The screenshot is as follows ）

 2. The second way is to use GuzzleHttp Upload ：

        $pathName = realpath('./111.png');
		$url = "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=ACCESSTOKEN&type=image";
		$description = array(
			'title' => '111.png',
			'introduction' =>  '111.png',
		);
		// $data['description'] = urldecode(json_encode($description));
        try{
            $client = new Client();
            $multipart = [
			        [
			            'name'     => 'media',
			            'contents' => fopen($pathName, 'r')
			        ],
			        [
			        	'name' => 'description',
			        	'contents' => urldecode(json_encode($description))
			        ]
			    ];
            $response = $client->request('POST', $url, [
            	'timeout' => 3,
                'multipart' => $multipart,
            ]);
            $response = json_decode($response->getBody(), true);
            var_dump($response);
        }catch(\Exception $e){
            echo $e->getMessage();
        }
