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;
  }
 }
})
