微信小程序wx.uploadfile, 利用PHP接口把本地圖片轉化為base64位。
網上到處都是粘貼復制的wx.uploadfile的解決方案, 但目前還沒有具體的代碼:
特意呈現出來給需要的伙伴們:
代碼:
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('文件類型不合法'); <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'].'文件類型不合法'); <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("解析失敗"); break; js代碼:
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; } } }) 總結
