🤖 AI解决方案
1. 错误翻译
原文：Your input exceeds the context window of this model. Please adjust your input and try again.
译文：你的输入超出了该模型的上下文窗口限制。请调整输入后重试。
2.原因分析
postToApi函数向API发送请求时，input参数长度超标（堆栈跟踪中async postToApi环节触发错误）。 3. 解决方案
以下为JavaScript分块/截断输入的修复示例（适配前端/Node.js场景）：
javascript
// 需替换为模型实际最大上下文（如GPT-3.5为4096、GPT-4为8192）
const MAX_CONTEXT = 4096; /
* 处理超长输入：截断或分块
* @param {string} input - 原始输入
* @returns {string|Array} 处理后结果（单段/分块数组）
*/
function handleLongInput(input) {
if (input.length <= MAX_CONTEXT) return input;
// 方案1：直接截断（保留前MAX_CONTEXT字符）
// return input.slice(0, MAX_CONTEXT);
// 方案2：分块处理（返回数组，后续分批调用API）
const chunks = [];
for (let i = 0; i < input.length; i += MAX_CONTEXT) {
chunks.push(input.slice(i, i + MAX_CONTEXT));
}
return chunks;
}
// 使用示例
const originalInput = "你的超长输入内容...";
const processed = handleLongInput(originalInput);
// 分块调用API（若返回数组）
if (Array.isArray(processed)) {
processed.forEach(chunk => {
// 调用API的逻辑（如postToApi(chunk)）
});
} else {
// 直接调用API（单段）
// postToApi(processed);
}
4. 预防措施
input.length > MAX_CONTEXT），提前拦截超长输入。 node-summary或OpenAI摘要API），减少冗余内容。 lodash.truncate（截断）、compromise（文本摘要）。
