Specially presented to partners who need it:

Code:

case 'imgBufferToBase64': 
<span style="white-space: pre;"> </span>$data=&#39;&#39;; 
<span style="white-space: pre;"> </span>file_put_contents("1.txt",var_export($_FILES,true)."\r\n",FILE_APPEND);

<span style="white-space: pre;">  </span>IO::Debug(&#39;解析成功&#39;,true,$data); 
<span style="white-space: pre;"> </span>} 
<span style="white-space: pre;"> </span>IO::Debug("解析失败"); 
break;

js code:

wx.uploadFile({

 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;
