如何自定义首页中的文章摘要?

[brtang181]

首页中会自动生成文章摘要, 但因为没有分行, 有时观感不是很好, 请问能否自定义摘要?

[XPoet]

Hexo 自带自定义截取文章摘要的功能。

使用截取符 <!-- more --> 截取的摘要，会以 Markdown 格式显示。

例如这篇文章的摘要：

---
title: Keep 主题使用指南
date: 2020-04-07 21:55:14
tags: [Hexo, Keep]
categories: [Keep]
sticky: 9999
---

如你所见，Keep 主题界面设计十分简洁、大气，同时也功能齐全、不失优雅，这正是 Keep 主题的开发理念。也曾尝试过花里胡哨，发现不仅配置繁琐、容易审美疲劳，而且背驰了写博客的初衷，记录生活、展示文字，应该才是搭建博客网站的最终追求，为此 Keep 主题应运而生。简约轻快、化繁为简、配置简单、突出内容、长期维护，如果你也喜欢或认可这些特点，一起来探索吧~

## 文档 | Documents

在使用 Keep 主题过程中，请仔细阅读[官方使用文档](https://keep-docs.xpoet.cn/)，绝大部分问题，都能在文档里找到参考。

首页摘要效果

[XPoet]

如果在文章中未添加 <!-- more --> 截取符，那么就会自动截取无格式的摘要，文章前180个字符

[NeeoMacLynch]

您好，我再文章中添加了截取符，但是在首页上仍是“自动截取无格式的摘要，文章前180个字符”

[XPoet]

@NeeoMacLynch

1、文章截取符的位置截图我看看 2、清空下浏览器缓存再刷新看看

[NeeoMacLynch]

@XPoet

清除缓存后仍然不行，另外使用反引号块实现代码高亮也不行，markdown 预览上有高亮效果，但是到 blog 上就没有显示了

[XPoet]

Keep 主题这些功能 都是正常可用的。是你配置问题： 你的 Hexo 配置文件发一下 文章的 md 文件也发一下

多亏了伟大的防火墙，Git push 一直都不太稳定，如果出现 `Failed to connect to github.com port 443: Timed out` 超时报错，一般通过设置代理或者取消代理并再次 push 以尝试是否能绕过长城，具体操作如下：

<!--more-->

### 查看当前代理

```Bash
git config --global http.proxy
git config --global https.proxy

@NeeoMacLynch

我用你的配置文件来测试，可以截取文章摘要呀

你重新初始一个 Hexo项目，再看看

[NeeoMacLynch]

@XPoet 重新创建后解决啦，感谢

[lamkuan]

一定要重新創建一個項目嗎。。。我也有一樣的問題。
