百度ueditor编辑器虽然强大,可是也有不足的地方。若是对ueditor流程不是很熟悉能够说走的弯路比较多,费力不讨好。下面呢,就是要解决ueditor遇到的问题。javascript
用ueditor上传图片遇到的问题是服务器错误php
虽然上传成功可是服务器返回出错,对于没有经验或者是初学者都回去百度搜,结果不是很理想。并且越走越偏。html
第一步:修改路径文件config.jsonjava
/* 先后端通讯相关的配置,注释只容许使用多行方式 */ { /* 上传图片配置项 */ "imageActionName": "uploadimage", /* 执行上传图片的action名称 */ "imageFieldName": "upfile", /* 提交的图片表单名称 */ "imageMaxSize": 4096000, /* 上传大小限制,单位B */ "imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"], /* 上传图片格式显示 */ "imageCompressEnable": true, /* 是否压缩图片,默认是true */ "imageCompressBorder": 1600, /* 图片压缩最长边限制 */ "imageInsertAlign": "none", /* 插入的图片浮动方式 */ "imageUrlPrefix": "", /* 图片访问路径前缀 */ "imagePathFormat": "/public/ueditor/php/image/{yyyy}{mm}{dd}/{time}{rand:6}", /* 上传保存路径,能够自定义保存路径和文件名格式 */ /* {filename} 会替换成原文件名,配置这项须要注意中文乱码问题 */ /* {rand:6} 会替换成随机数,后面的数字是随机数的位数 */ /* {time} 会替换成时间戳 */ /* {yyyy} 会替换成四位年份 */ /* {yy} 会替换成两位年份 */ /* {mm} 会替换成两位月份 */ /* {dd} 会替换成两位日期 */ /* {hh} 会替换成两位小时 */ /* {ii} 会替换成两位分钟 */ /* {ss} 会替换成两位秒 */ /* 非法字符 \ : * ?

咱们发现虽然改了随意路径(/public/ueditor/php/image/)上传大小能够根据本身的需求修改。可是还会服务器返回出错,并且this request has no preview available(没有任何请求)。linux
第二步:打开controller.php文件web
1 <?php
2 //header('Access-Control-Allow-Origin: http://www.baidu.com'); //设置http://www.baidu.com容许跨域访问
3 //header('Access-Control-Allow-Headers: X-Requested-With,X_Requested_With'); //设置容许的跨域header
4 date_default_timezone_set("PRC"); 5 error_reporting(E_ERROR); 6 header("Content-Type: text/html; charset=utf-8"); 7 $CONFIG = json_decode(preg_replace("/\/\*[\s\S]+?\*\//", "", file_get_contents("config.json")), true); 8 $action = $_GET['action']; 9 switch ($action) { 10 case 'config': 11 $result = json_encode($CONFIG); 12 break; 13 14 /* 上传图片 */ 15 case 'uploadimage': 16 /* 上传涂鸦 */ 17 case 'uploadscrawl': 18 /* 上传视频 */ 19 case 'uploadvideo': 20 /* 上传文件 */ 21 case 'uploadfile': 22 $result = include("action_upload.php"); 23 break; 24 25 /* 列出图片 */ 26 case 'listimage': 27 $result = include("action_list.php"); 28 break; 29 /* 列出文件 */ 30 case 'listfile': 31 $result = include("action_list.php"); 32 break; 33 34 /* 抓取远程文件 */ 35 case 'catchimage': 36 $result = include("action_crawler.php"); 37 break; 38 39 default: 40 $result = json_encode(array( 41 'state'=> '请求地址出错' 42 )); 43 break; 44 } 45 46 /* 输出结果 */ 47 if (isset($_GET["callback"])) { 48 if (preg_match("/^[\w_]+$/", $_GET["callback"])) { 49 echo htmlspecialchars($_GET["callback"]) . '(' . $result . ')'; 50 } else { 51 echo json_encode(array( 52 'state'=> 'callback参数不合法' 53 )); 54 } 55 } else { 56 echo $result; 57 }菜鸟在调试controller.php常常忽略date_default_timezone_set("PRC");禁止显示错误。
咱们发现error_reporting(E_ERROR);,关于ueditor资料遇到上传不成功都会说路径,而不会说controller.php文件下:error_reporting(E_ERROR)。能够修改为error_reporting(E_ALL)能够看到
报错位置是Uploader.class.php on line 248。
第三步:打开Uploader.class.php

发现248行因为误删,致使报错。那咱们就修改248行代码。修改完成后再次刷新/ueditor/php/controller.php?action=uploadimage&encode=utf-8页面。json
刷新页面完成又报/ueditor/php/Uploader.class.php on line 66 无论它。咱们再次开启error_reporting(E_ERROR);后端
咱们试一次看看是否成功跨域
成功了(备注:在linux系统下修改路径要注意权限)。服务器
