错误翻译

原文：Error fetching from https://generativelanguage.googleapis.com/v1beta/models/gemini-2.5-pro:streamGenerateContent?alt=sse: fetch failed
译文：从Google生成式AI API端点获取数据时发生fetch失败错误

原因分析

网络请求失败 - 客户端无法连接到Google Generative AI API服务器，主要原因可能包括：

解决方案

``javascript
// 方案1：添加网络错误处理和重试机制
async function callGoogleAIWithRetry(prompt, maxRetries = 3) {
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
const response = await fetch('https://generativelanguage.googleapis.com/v1beta/models/gemini-pro:generateContent', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': Bearer ${process.env.GOOGLE_API_KEY}
},
body: JSON.stringify({ contents: [{ parts: [{ text: prompt }] }] })
});

if (!response.ok) throw new Error(HTTP error! status: ${response.status});
return await response.json();

} catch (error) {
console.warn(Attempt ${attempt} failed:, error.message);
if (attempt === maxRetries) throw error;
await new Promise(resolve => setTimeout(resolve, 1000 * attempt)); // 指数退避
}
}
}

// 方案2：检查并修正API端点（注意：gemini-2.5-pro可能不存在）
const correctEndpoint = 'https://generativelanguage.googleapis.com/v1beta/models/gemini-pro:generateContent';
