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; 
  } 
 } 
})
