解析响应数据失败: ${err instanceof Error ? err.message : String(err)

Error message

解析响应数据失败: ${err instanceof Error ? err.message : String(err)}

What it means

If responseText is non-empty but JSON.parse throws (malformed JSON, HTML error page, truncated body), the inner catch logs the raw data and rethrows as '解析响应数据失败: <original message>' (project/aitoearn-electron/electron/plat/douyin/index.ts:2369). The outer catch may retry it; on the final attempt the message is additionally wrapped as '请求失败: 解析响应数据失败: ...'. It indicates Douyin (or an intermediary) returned a non-JSON body.

Solutions

1. Inspect the console.error output '导致错误的原始数据:' to see the raw body — if it is HTML, refresh the Douyin cookie or complete verification (captcha/QR login).
2. Refresh the Douyin session cookie and re-run the operation.
3. Check whether the request is going through a proxy/captive portal that injects HTML, and bypass it.
4. Retry with backoff for transient truncation; verify the endpoint URL is still current after Douyin API updates.

Example fix

// before
const res = await douyinService.somePostFormDataOp(cookie, data);
// after
try {
  const res = await douyinService.somePostFormDataOp(cookie, data);
} catch (e) {
  if (String(e.message).startsWith('解析响应数据失败')) {
    // raw body was logged; refresh cookie or handle HTML/captcha page
  }
  throw e;
}

function isJsonObject(text: string): boolean {
  try {
    const v = JSON.parse(text);
    return typeof v === 'object' && v !== null;
  } catch {
    return false;
  }
}

try {
  const result = await douyinService.someOp(cookie, data);
} catch (e) {
  const msg = String(e.message);
  if (msg.startsWith('解析响应数据失败') || msg.includes('解析响应数据失败')) {
    // raw body was logged via console.error; if HTML → refresh cookie / handle captcha
    await refreshDouyinCookie();
  } else throw e;
}

When it happens

Trigger: Any postFormData call where Douyin responds with HTML (e.g. a login/captcha/risk-control page), a truncated body, or garbled encoding instead of JSON — the parse throws SyntaxError which is rethrown with this prefix.

Common situations: Expired cookie causing Douyin to serve an HTML login/verification page instead of the JSON API response; a captive portal or proxy injecting HTML; CDN/server returning a compressed or corrupted body; endpoint URL changes after a Douyin API version bump.

Understand the failure class

Background: "Invalid JSON response" and "Failed to parse response" errors: when an API answers 200 but the body isn't the JSON your library expected — this error's family across 28 libraries.
