求助：关于Popup Search脚本自定义翻译引擎无效的问题

Saltboar

Popup Search脚本是一款划词弹窗便捷搜索的脚本，由于作者已停更，脚本中的Deepl翻译引擎失效，所以我借助AI大模型，根据Deeplx的调用示例修改了相关内容，但实测依然无法连接，求大神解惑。

注：API地址在其他脚本中可用。

原代码节选

onTranslate = function (engine) {
  popData.bTrans = 1;
  $("#transPanel").empty().append(`<div style='padding:10px;'><img src='${popData.icons.pending}' /></div>`).show();
  $('#popupWrapper').hide();
  fixPos(document.defaultView.getSelection());
  return doRequest(engine, 0, 2000);
};

doRequest = function (engine, i, wait) {
  var ErrHandle, lang;
  ErrHandle = function () {
    return doRequest(engine, i + 1, wait + 2000);
  };
  if (i >= 2) {
    ErrHandle = ajaxError;
  }
  lang = navigator.language || navigator.userLanguage || "zh-CN";
  if (engine === 'google') {
    return GM_xmlhttpRequest({
      method: 'POST',
      url: `https://translate.google.com/translate_a/single?client=gtx&dj=1&q=${popData.text}&sl=auto&tl=${lang}&hl=${lang}&ie=UTF-8&oe=UTF-8&source=icon&dt=t&dt=bd`,
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        "Accept-Encoding": "gzip, deflate"
      },
      timeout: wait,
      onload: parseTranslationGoogle,
      onerror: ErrHandle,
      ontimeout: ErrHandle
    });
  } else if (engine === 'deepl') {
    return GM_xmlhttpRequest({
      method: 'POST',
      url: "https://api-free.deepl.com/v2/translate??auth_key=aa09f88d-ab75-3488-b8a3-18ad27a35870:fx",
      data: "auth_key=aa09f88d-ab75-3488-b8a3-18ad27a35870:fx&target_lang=ZH&text=" + popData.text,
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded'
      },
      timeout: wait,
      onload: parseTranslationDeepl,
      onerror: ErrHandle,
      ontimeout: ErrHandle
    });
      } else {
    return GM_xmlhttpRequest({
      method: 'POST',
      url: "http://api.interpreter.caiyunai.com/v1/translator",
      headers: {
        'Content-Type': 'application/json',
        "X-Authorization": "token " + "3975l6lr5pcbvidl6jl2"
      },
      data: JSON.stringify({
        "source": [popData.text],
        "trans_type": "auto2zh",
        "request_id": "demo",
        "detect": true
      }),
      timeout: wait,
      onload: parseTranslationCaiyun,
      onerror: ErrHandle,
      ontimeout: ErrHandle
    });
  }
};

parseTranslationDeepl = function (responseDetails) {
  var RTxt, Result;
  if (!popData.bTrans) {
    return;
  }
  try {
    RTxt = JSON.parse(responseDetails.responseText);
  } catch (error) {
    log(JSON.stringify(responseDetails));
    return ajaxError(responseDetails);
  }
  Result = `<div id=\"tranRst\" style=\"font-size:13px;overflow:auto;padding:5px 12px;\"> <div style=\"line-height:200%;font-size:13px;\"> ${RTxt.translations[0].text} </div> </div>`;
  $('#transPanel').empty().append(Result).show();
  fixPos(document.defaultView.getSelection());
};

Deeplx调用示例

var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");

var raw = JSON.stringify({
  "text": "Hello, world!",
  "source_lang": "auto",
  "target_lang": "ZH"
});

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: raw,
  redirect: 'follow'
};

fetch("https://api.deeplx.org/translate", requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

修改的代码

else if (engine === 'deeplx') {
    return GM_xmlhttpRequest({
      method: 'POST',
      url: "https://api.deeplx.org/translate",
      headers: {
        'Content-Type': 'application/json'
      },
      data: JSON.stringify({
        "text": [popData.text],
        "source_lang": "auto",
        "target_lang": "ZH"
      }),
      timeout: wait,
      onload: parseTranslationDeepl,
      onerror: ErrHandle,
      ontimeout: ErrHandle
    });
  }
