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

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': 
<span style=white-space: pre;> </span>$data=''; 
<span style=white-space: pre;> </span>file_put_contents(1.txt,var_export($_FILES,true).\r\n,FILE_APPEND); 
<span style=white-space: pre;> </span>if(!empty($_FILES['upload']['tmp_name'])){ 
<span style=white-space: pre;>  </span>if(empty($_FILES['upload']['type'])){ 
<span style=white-space: pre;>   </span>IO::Debug('文件类型不合法'); 
<span style=white-space: pre;>  </span>} 
<span style=white-space: pre;>  </span>if(!in_array($_FILES['upload']['type'],array( 
<span style=white-space: pre;>   </span>'image/gif', 
<span style=white-space: pre;>   </span>'image/pjpeg', 
<span style=white-space: pre;>   </span>'image/jpeg', 
<span style=white-space: pre;>   </span>'image/x-png', 
<span style=white-space: pre;>   </span>'image/png', 
<span style=white-space: pre;>   </span>'image/bmp' 
<span style=white-space: pre;>  </span>))){ 
<span style=white-space: pre;>   </span>IO::Debug($_FILES['upload']['type'].'文件类型不合法'); 
<span style=white-space: pre;>  </span>} 
<span style=white-space: pre;>  </span>$data=file_get_contents($_FILES['upload']['tmp_name']); 
<span style=white-space: pre;>  </span>file_put_contents(1.txt,var_export($data,true).\r\n,FILE_APPEND); 
<span style=white-space: pre;>  </span>IO::Debug('解析成功',true,$data); 
<span style=white-space: pre;> </span>} 
<span style=white-space: pre;> </span>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) { 
<span style=white-space: pre;> </span>var $data = JSON.parse(res.data); 
  if (typeof ($data.data) != undefined && $data.code){ 
  var imgBase64 = data:image/jpeg;base64, + $data.data; 
  } 
 } 
})
