微信小程序wx.uploadfile, 利用PHP接口把本地图片转化为base64流.

网上到处都是粘贴复制的wx.uploadfile的解决方案, 但目前还没有具体的代码:

特意呈现出来给需要的伙伴们:

代码:

case 'imgBufferToBase64':
	$data='';

	file_put_contents("1.txt",var_export($_FILES,true)."\r\n",FILE_APPEND);
	if(!empty($_FILES['upload']['tmp_name'])){
		if(empty($_FILES['upload']['type'])){
			IO::Debug('文件类型不合法');
		}
		if(!in_array($_FILES['upload']['type'],array(
			'image/gif',
			'image/pjpeg',
			'image/jpeg',
			'image/x-png',
			'image/png',
			'image/bmp'
		))){
			IO::Debug($_FILES['upload']['type'].'文件类型不合法');
		}
		$data=file_get_contents($_FILES['upload']['tmp_name']);
		file_put_contents("1.txt",var_export($data,true)."\r\n",FILE_APPEND);
		IO::Debug('解析成功',true,$data);
	}
	IO::Debug("解析失败");
break;

js代码:

wx.uploadFile({
  url: 'https://' + app.globalData.host + '/api/?sign=' + sign, 
  filePath: tempFilePaths[0],
  name: 'upload',
  header: { 
	"content-type": "multipart/form-data",
	"content-type": "application/x-www-form-urlencoded"
  },
  formData: formData,
  success: function (res) {

	var $data = JSON.parse(res.data);

     if (typeof ($data.data) != "undefined" && $data.code){
        var imgBase64 = "data:image/jpeg;base64," + $data.data;
     }
  }
})
