Hexo 加入图片无法显示--解决方案

测试实例:

插件安装与配置,

首先我们需要安装一个图片路径转换的插件，这个插件名字是 hexo-asset-image

​ sudo npm install https://github.com/CodeFalling/hexo-asset-image --save

核心部分,需要修改 index.js文件

'use strict';
var cheerio = require('cheerio');

// http://stackoverflow.com/questions/14480345/how-to-get-the-nth-occurrence-in-a-string
function getPosition(str, m, i) {
  return str.split(m, i).join(m).length;
}

var version = String(hexo.version).split('.');
hexo.extend.filter.register('after_post_render', function(data){
  var config = hexo.config;
  if(config.post_asset_folder){
    var link = data.permalink;
  if(version.length > 0 && Number(version[0]) == 3)
     var beginPos = getPosition(link, '/', 1) + 1;
  else
    var beginPos = getPosition(link, '/', 3) + 1;
    // In hexo 3.1.1, the permalink of "about" page is like ".../about/index.html".
      var endPos = link.lastIndexOf('/') + 1;

    link = link.substring(beginPos, endPos) ;
    var toprocess = ['excerpt', 'more', 'content'];
    for(var i = 0; i < toprocess.length; i++){
      var key = toprocess[i];

      var $ = cheerio.load(data[key], {
        ignoreWhitespace: false,
        xmlMode: false,
        lowerCaseTags: false,
        decodeEntities: false
      });

      $('img').each(function(){
        if ($(this).attr('src')){
          // For windows style path, we replace '\' to '/'.
          var src = $(this).attr('src').replace('\\', '/');
          if(!/http[s]*.*|\/\/.*/.test(src) && !/^\s*\//.test(src)) {
            // For "about" page, the first part of "src" can't be removed.
            // In addition, to support multi-level local directory.
            var linkArray = link.split('/').filter(function(elem){
              return elem != '';
            });
            var srcArray = src.split('/').filter(function(elem){
              return elem != '' && elem != '.';
            });
            if(srcArray.length > 1)
            srcArray.shift();
            src = srcArray.join('/');
            $(this).attr('src', config.root + link + src);
            console.info&&console.info("update link as:-->"+config.root + link + src);
          }
        }else{
          console.info&&console.info("no src attr, skipped...");
          console.info&&console.info($(this));
        }
      });
      data[key] = $.html();
    }
  }
});

打开_config.yml文件，修改下述内容

​ post_asset_folder: true
​ url: http://localhost:4000/修改为对应的地址
