# 创建并行步骤
|
||
|
||
让我们创建三个可以同时运行的分析步骤来分析内容的不同方面。
|
||
|
||
## 创建分析步骤
|
||
|
||
将这三种步骤添加到您的工作流文件中：
|
||
|
||
```typescript
|
||
// SEO Analysis
|
||
const seoAnalysisStep = createStep({
|
||
id: "seo-analysis",
|
||
description: "SEO optimization analysis",
|
||
inputSchema: z.object({
|
||
content: z.string(),
|
||
type: z.enum(["article", "blog", "social"]).default("article"),
|
||
}),
|
||
outputSchema: z.object({
|
||
seoScore: z.number(),
|
||
keywords: z.array(z.string()),
|
||
}),
|
||
execute: async ({ inputData }) => {
|
||
console.log("🔍 Running SEO analysis...");
|
||
await new Promise((resolve) => setTimeout(resolve, 800));
|
||
|
||
const words = inputData.content.toLowerCase().split(/\s+/);
|
||
const keywords = words.filter((word) => word.length > 4).slice(0, 3);
|
||
|
||
return {
|
||
seoScore: Math.floor(Math.random() * 40) + 60,
|
||
keywords,
|
||
};
|
||
},
|
||
});
|
||
|
||
// Readability Analysis
|
||
const readabilityStep = createStep({
|
||
id: "readability-analysis",
|
||
description: "Content readability analysis",
|
||
inputSchema: z.object({
|
||
content: z.string(),
|
||
type: z.enum(["article", "blog", "social"]).default("article"),
|
||
}),
|
||
outputSchema: z.object({
|
||
readabilityScore: z.number(),
|
||
gradeLevel: z.string(),
|
||
}),
|
||
execute: async ({ inputData }) => {
|
||
console.log("📖 Running readability analysis...");
|
||
await new Promise((resolve) => setTimeout(resolve, 600));
|
||
|
||
const sentences = inputData.content.split(/[.!?]+/).length;
|
||
const words = inputData.content.split(/\s+/).length;
|
||
const avgWordsPerSentence = words / sentences;
|
||
|
||
const score = Math.max(0, 100 - avgWordsPerSentence * 3);
|
||
const gradeLevel = score > 80 ? "Easy" : score > 60 ? "Medium" : "Hard";
|
||
|
||
return {
|
||
readabilityScore: Math.floor(score),
|
||
gradeLevel,
|
||
};
|
||
},
|
||
});
|
||
|
||
// Sentiment Analysis
|
||
const sentimentStep = createStep({
|
||
id: "sentiment-analysis",
|
||
description: "Content sentiment analysis",
|
||
inputSchema: z.object({
|
||
content: z.string(),
|
||
type: z.enum(["article", "blog", "social"]).default("article"),
|
||
}),
|
||
outputSchema: z.object({
|
||
sentiment: z.enum(["positive", "neutral", "negative"]),
|
||
confidence: z.number(),
|
||
}),
|
||
execute: async ({ inputData }) => {
|
||
console.log("😊 Running sentiment analysis...");
|
||
await new Promise((resolve) => setTimeout(resolve, 700));
|
||
|
||
const content = inputData.content.toLowerCase();
|
||
const positiveWords = ["good", "great", "excellent", "amazing"];
|
||
const negativeWords = ["bad", "terrible", "awful", "horrible"];
|
||
|
||
const positive = positiveWords.filter((word) =>
|
||
content.includes(word),
|
||
).length;
|
||
const negative = negativeWords.filter((word) =>
|
||
content.includes(word),
|
||
).length;
|
||
|
||
let sentiment: "positive" | "neutral" | "negative" = "neutral";
|
||
if (positive > negative) sentiment = "positive";
|
||
if (negative > positive) sentiment = "negative";
|
||
|
||
return {
|
||
sentiment,
|
||
confidence: Math.random() * 0.3 + 0.7, // 0.7-1.0
|
||
};
|
||
},
|
||
});
|
||
```
|
||
|
||
## 注意时间
|
||
|
||
每个步骤都有不同的模拟处理时间：
|
||
|
||
- SEO：800毫秒
|
||
- 可读性：600毫秒
|
||
- 情感：700毫秒
|
||
|
||
当顺序运行时，总时间约为2.2秒。当并行运行时，总时间约为800毫秒（最长步骤）！
|
||
|
||
接下来，您将学习如何使用 `.parallel()` 方法并行运行这些步骤。
