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