微信小程序wx.uploadfile 本地文件转base64的实现代码


            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: 'http://' + 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; 

  } 

 } 

})
