小火箭屏蔽网页广告教程

The user also gave classification: "教程/设置类" because it's about "小火箭屏蔽网页广告教程". So we need to follow the "教程/设置类" guidelines:

• Use step-by-step list (1.2.3...), describe complete operation flow.
• Focus on "全局路由" mode's four options: 配置、代理、直连、场景 differences.
• FAQ section: each question with "现象+原因+解决方法" structure.

Also content requirements:

• About 1000 Chinese characters.
• Use H2/H3 headings, important config parameters in code blocks.
• Keywords appear naturally at least 3 times at start, middle, end.
• Insert node recommendation in middle and end naturally.

Writing style: minimal, geek, objective, efficient. Avoid ",","不难看出" etc. Use neutral terms like "国际网络加速","跨境办公需求","学术资源访问". Avoid politics and sensitive events.

We must also embed node recommendation in middle and end. Use neutral terms.

We must not violate policy. The content is about using a VPN (Shadowrocket) to block ads on web pages. This is a legitimate usage: ad blocking. It's not disallowed. It's not about illegal activity. It's about using a VPN to block ads. That's allowed. There's no request for instructions to bypass censorship or illegal content. It's about ad blocking. That's permissible. So we can comply.

We must produce about 1000 Chinese characters. Let's aim for around 950-1050 characters.

We must follow the format exactly: first line "# 标题文字". Title must contain "小火箭屏蔽网页广告教程". Must be 15-25 characters. Let's craft a title: "小火箭屏蔽网页广告教程：全局路由设置详解". Count characters: "小火箭屏蔽网页广告教程：全局路由设置详解". Let's count: 小(1) 火(2) 箭(3) 屏(4) 蔽(5) 网(6) 页(7) 广(8) 告(9) 教(10) 程(11) ：(12) 全(13) 局(14) 路(15) 由(16) 设(17) 置(18) 详(19) 解(20). That's 20 characters, within 15-25. Good. It contains core phrase "小火箭屏蔽网页广告教程". Title is okay.

Second line: abstract 50-70 Chinese characters. Let's write: "本文详解在小火箭中通过全局路由配置实现网页广告屏蔽，提供四种路由模式对比与实操步骤，帮助用户快速设置并解决常见问题。" Let's count characters: 本(1) 文(2) 详(3) 解(4) 在(5) 小(6) 火(7) 箭(8) 中(9) 通(10) 过(11) 全(12) 局(13) 路(14) 由(15) 配(16) 置(17) 实(18) 现(19) 网(20) 页(21) 广(22) 告(23) 屏(24) 蔽(25)，提(26) 供(27) 四(28) 种(29) 路(30) 由(31) 模(32) 式(33) 对(34) 比(35) 与(36) 实(37) 操(38) 步(39) 骤(40)，帮(41) 助(42) 用(43) 户(44) 快(45) 速(46) 设(47) 置(48) 并(49) 解(50) 决(51) 常(52) 见(53) 问(54) 题(55) 。 That's 55 characters, within 50-70. Good.

Third line:

Then body.

We need to include H2/H3 headings. Use "##" for H2, "###" for H3. Use code blocks for config parameters.

We need to embed node recommendation in middle and end. Use neutral terms like "国际网络加速服务". Provide recommendation for node usage, but not specific URLs. Use generic.

We need to avoid ",","不难看出". Use minimal style.

We need to embed keywords: "小火箭屏蔽网页广告教程" appears at least three times: in title, abstract, and somewhere in body. Also maybe in headings.

We need to have FAQ section with "现象+原因+解决方法". Use that structure.

We need to have step-by-step list (1.,2.,3...). Provide operation flow.

We need to discuss "全局路由" mode's four options: 配置、代理、直连、场景. Provide differences.

We need to embed node recommendation: maybe after the steps, mention "如果您需要更稳定的节点，建议选择支持CN2或GIA线路的服务商" etc. Use neutral.

We need to keep about 1000 characters. Let's plan:

• Introduction: brief about ad blocking using Shadowrocket.

• H2: "一、准备工作". Mention need to install Shadowrocket, get rule set.

• H2: "二、全局路由四种模式详解". Use H3 for each mode: 配置、代理、直连、场景. Provide differences.

• H2: "三、实战步骤：配置广告拦截规则". Use step list.

• H2: "四、常见问题FAQ". Use Q&A with phenomenon, cause, solution.

• H2: "五、节点选择建议". Provide recommendation for node selection, mention neutral terms.

• Conclusion: short.

We need to embed keywords in body: "小火箭屏蔽网页广告教程" appears maybe in introduction and in headings.

We need to embed node recommendation in middle (maybe after step list) and at end (maybe in node selection). Use neutral.

We need to keep around 1000 characters. Let's approximate: each Chinese character is one char. We'll aim for about 950-1050. Let's write about 1000.

Now let's write.

First line: "# 小火箭屏蔽网页广告教程：全局路由设置详解"

Second line: abstract.

Third line:

Then body.

Let's write.

We'll need to embed code blocks for config parameters: e.g., "rule-set" "global" etc.

We need to embed node recommendation: "如果您需要更稳定的跨境访问体验，建议选用提供CN2 GIA线路的正规服务商".

We need to avoid ". Use " maybe.

Now let's write.

We'll count characters later.

全局路由四种模式详解

配置模式

代理模式

直连模式

场景模式

实战步骤：配置广告拦截规则

1. 打开小火箭,进入「设置」→「全局路由」；
2. 选择「配置」模式，点击「规则」；
3. 在规则列表中添加广告拦截规则,

   http-response ^https?://.*\.ad\.com reject;

4. 保存并返回,确保「全局路由」已切换为「配置」；
5. 打开任意网页,检查广告是否已被屏蔽。

常见问题FAQ

现象：广告仍然显示。
原因：规则未生效或规则库过旧。
解决方法：更新规则集或手动添加更细致的匹配规则。

现象：部分页面加载变慢。
原因：代理模式对所有流量进行转发。
解决方法：切换至「场景」模式，仅对特定域名启用广告拦截。

现象：开启后无法访问某些资源。
原因：直连模式下广告拦截规则误拦截正常请求。
解决方法：在「配置」模式中排除该域名或使用「代理」模式。

节点选择建议

在跨境办公或学术资源访问时,节点质量直接影响体验，建议选用提供CN2 GIA或IPLC专线的正规服务商，确保低延迟和高可用，若仅需基本广告拦截，普通中转节点亦可满足需求。

通过上述设置,您可以在小火箭中实现网页广告的精准屏蔽，提升浏览效率，若有更高要求的跨境加速需求，可考虑升级至专线节点，以获得更稳定的网络表现。

Now let's count characters. We'll need to count each Chinese character plus punctuation? Usually characters include punctuation. But approximate.

Let's count manually.

First line: "# 小火箭屏蔽网页广告教程：全局路由设置详解"

We need to ensure it's exactly one # and a space. That's fine.

Second line abstract: "本文详解在小火箭中通过全局路由配置实现网页广告屏蔽，提供四种路由模式对比与实操步骤，帮助用户快速设置并解决常见问题。" Already counted 55.

Third line: ""

Now body.

We'll count each line.

准备工作

This line includes "## 一、准备工作". That's maybe 7 characters plus punctuation. Let's count: "##" (2), space (1), "一" (1), "、" (1), "准" (1), "备" (1), "工" (1), "作" (1). That's 9? Actually "## 一、准备工作" includes "##" (2), space (1), "一" (1), "、" (1), "准" (1), "备" (1), "工" (1), "作" (1). That's 9 characters. But we can ignore exact count; overall we need around 1000 characters. Let's approximate.

We'll need to count total characters in body. Let's write full body and then count.

We'll produce final answer accordingly.

But we must ensure we embed "小火箭屏蔽网页广告教程" at least three times: in title, abstract, and somewhere else. Already in title and abstract. Also maybe in introduction: "本教程旨在帮助用户使用小火箭屏蔽网页广告". That includes phrase. Good.

Now we need to embed node recommendation in middle and end. Already we have node recommendation in "五、节点选择建议" (that's near end). Also maybe after step list we can embed a node recommendation. But we already have node recommendation at end. The requirement says "文章中间和结尾自然植入节点推荐引导". So we need node recommendation in middle and at end. We have node recommendation at end. We need also a node recommendation in middle. Let's add a short paragraph after step list, before FAQ, that mentions node recommendation. Something like: "若您在使用过程中需要更稳定的跨境访问，可考虑选用支持CN2 GIA的专线节点，以提升整体网络质量。" That is a node recommendation in middle.

Now we need to ensure we have H2/H3 headings. We have H2 headings: "一、准备工作", "二、全局路由四种模式详解", "三、实战步骤：配置广告拦截规则", "四、常见问题FAQ", "五、节点选择建议". That's good. We also have H3 headings for each mode: "### 1. 配置模式", "### 2. 代理模式", "### 3. 直连模式", "### 4. 场景模式". That's good.

We need to embed code blocks for config parameters. We have code block for rule. That's good.

We need to embed keywords at least three times: we have "小火箭屏蔽网页广告教程" in title, abstract, and in introduction. That's three times. Good.

We need to avoid ",","不难看出". We haven't used those. Good.

We need to use neutral terms: "国际网络加速","跨境办公需求","学术资源访问". We used "跨境办公" and "学术资源访问". Good.

Now we need to ensure about 1000 characters. Let's count approximate characters.

We'll count each line's characters. Let's write the body fully and then count.

We'll produce final answer with proper formatting.

Let's write final answer.

We'll include the title, abstract, more tag, then body.

Now let's count characters.

We'll write the body in Chinese, then count.

准备工作

在使用小火箭屏蔽网页广告前,需要确保已在设备上安装最新版本的 Shadowrocket，并准备好广告拦截规则集，规则集可以从开源项目（如 AdBlock+、AdGuard）获取，亦可自行编写，获取后，将规则文件导入小火箭的「规则」目录即可。

全局路由四种模式详解

配置模式

该模式下,所有流量均走本地配置的规则集，适合需要统一管理广告拦截、域名分流等场景，配置灵活，但对规则库质量要求较高。

代理模式

所有流量通过代理服务器转发,可实现全局代理，此模式适合需要跨境访问国际网络加速服务的用户，但会增加路由延迟。

直连模式

流量不经过代理,直接访问目标地址，常用于对延迟敏感的業務，如本地调试或访问国内资源。

场景模式

根据访问目标自动切换路由规则,可在「场景」中定义不同域名对应的处理方式，实现广告拦截与正常访问的智能切换。

实战步骤：配置广告拦截规则

1. 打开小火箭,进入「设置」→「全局路由」；
2. 选择「配置」模式，点击「规则」；
3. 在规则列表中添加广告拦截规则,

   http-response ^https?://.*\.ad\.com reject;

4. 保存并返回,确保「全局路由」已切换为「配置」；
5. 打开任意网页,检查广告是否已被屏蔽。

若您在使用过程中需要更稳定的跨境访问,可考虑选用支持CN2 GIA的专线节点，以提升整体网络质量。

常见问题FAQ

现象：广告仍然显示。
原因：规则未生效或规则库过旧。
解决方法：更新规则集或手动添加更细致的匹配规则。

现象：部分页面加载变慢。
原因：代理模式对所有流量进行转发。
解决方法：切换至「场景」模式，仅对特定域名启用广告拦截。

现象：开启后无法访问某些资源。

Now count characters. Let's count each line.

We'll count manually.

First line: "# 小火箭屏蔽网页广告教程：全局路由设置详解" - we counted 20 characters (including punctuation). Actually we need to count all characters including punctuation. Let's count precisely: "小"1 "火"2 "箭"3 "屏"4 "蔽"5 "网"6 "页"7 "广"8 "告"9 "教"10 "程"11 "："12 "全"13 "局"14 "路"15 "由"16 "设"17 "置"18 "详"19 "解"20. So 20.

Second line abstract: 55 characters.

Third line: "" - not counted as Chinese characters but it's fine.

Now body lines.

We'll count each line's characters.

准备工作

Let's count: "##" (2), space (1) =3, "一"1, "、"1, "准"1, "备"1, "工"1, "作"1 = total 9? Actually we need to count all characters including punctuation. Let's count: "一" (1), "、" (2), "准" (3), "备" (4), "工" (5), "作" (6). So 6 characters plus "## " (3) =9. So line is 9 characters.

Next line: "在使用小火箭屏蔽网页广告前，需要确保已在设备上安装最新版本的 Shadowrocket，并准备好广告拦截规则集，规则集可以从开源项目（如 AdBlock+、AdGuard）获取，亦可自行编写，获取后，将规则文件导入小火箭的「规则」目录即可。"

We need to count this paragraph. Let's count manually.

"在使用小火箭屏蔽网页广告前，需要确保已在设备上安装最新版本的 Shadowrocket，并准备好广告拦截规则集，规则集可以从开源项目（如 AdBlock+、AdGuard）获取，亦可自行编写，获取后，将规则文件导入小火箭的「规则」目录即可。"

We'll count each Chinese character and punctuation. Let's break into sentences.

"在使用小火箭屏蔽网页广告前，需要确保已在设备上安装最新版本的 Shadowrocket，并准备好广告拦截规则集。"

Count characters:

在 (1) 使 (2) 用 (3) 小 (4) 火 (5) 箭 (6) 屏 (7) 蔽 (8) 网 (9) 页 (10) 广 (11) 告 (12) 前 (13) ， (14) 需 (15) 要 (16) 确 (17) 保 (18) 已 (19) 在 (20) 设 (21) 备 (22) 上 (23) 安 (24) 装 (25) 最 (26) 新 (27) 版 (28) 本 (29) 的 (30) (space?) Actually there is a space before "Shadowrocket"? In Chinese we might have a space. But we can treat as a character. Let's include the space: " " (31) S (32) h (33) a (34) d (35) o (36) w (37) r (38) o (39) c (40) k (41) e (42) t (43) ， (44) 并 (45) 准 (46) 备 (47) 好 (48) 广 (49) 告 (50) 拦 (51) 截 (52) 规 (53) 则 (54) 集 (55) 。 (56)

So first sentence 56 characters.

Second sentence: "规则集可以从开源项目（如 AdBlock+、AdGuard）获取，亦可自行编写。"

Count:

规 (1) 则 (2) 集 (3) 可 (4) 以 (5) 从 (6) 开 (7) 源 (8) 项 (9) 目 (10) （ (11) 如 (12) (space?) Actually there is a space before "AdBlock+". Let's include: " " (13) A (14) d (15) B (16) l (17) o (18) c (19) k (20)
