linkedin voyager api:从代码调用 API 时响应无效

linkedin voyager api : Invalid response when calling API from code

我正在使用这个 linkedin-private-api 连接到 linkedin voyager 的库 api.

当我 运行 此代码时,我得到一个无效的 json 响应,类似于这样的内容:�/J�>�2:��������i ��f{��|tV4����>X��+��0

但是当我使用 Postman 时,我得到了有效的 json 响应


    "data": {
        "metadata": {
            "type": "TypeaheadFindByType",
            "id": "ff39d918-5e52-4a14-9aa3-6c37c72cb81b",
            "$type": "com.linkedin.voyager.typeahead.TypeaheadMetadata"
        },
        "entityUrn": "urn:li:collectionResponse:IFrGi77656cS3A4SqIFwTMfpqxVjguPOPn6DHgNnpiQ=",
        "elements": [
            {
                "targetUrn": "urn:li:fs_geo:103688978",
                "text": {
                    "text": "Sousse Governorate, Tunisia",
                    "$type": "com.linkedin.pemberly.text.AttributedText"
                },
                "dashTargetUrn": "urn:li:fsd_geo:103688978",
                "type": "GEO",
                "trackingId": "JLoPDNEmRo2BEEQr26vinw==",
                "$type": "com.linkedin.voyager.typeahead.TypeaheadHitV2"
            }
        }

这是完整的 nodejs 测试代码:

const {Client} = require('linkedin-private-api');
const https = require('https')

test();

async function test() {

const client = new Client();

await client.login.userPass({
    username: "username",
    password: "password"
});

var _headers = client.request.request.defaults.headers

const options = {
  hostname: 'www.linkedin.com',
  path: '/voyager/api/typeahead/hitsV2?keywords=USA&origin=OTHER&q=type&queryContext=List(geoVersion-%3E3,bingGeoSubTypeFilters-%3EMARKET_AREA%7CCOUNTRY_REGION%7CADMIN_DIVISION_1%7CCITY)&type=GEO',
  method: 'GET',
  headers: _headers
}


https.get(options, function (res) {
    var json = '';
    res.on('data', function (chunk) {
        json += chunk;
    });
    res.on('end', function () {
        if (res.statusCode === 200) {
            try {
                // data is available here:
                console.log(json);
            } catch (e) {
                console.log('Error parsing JSON!');
            }
        } else {
            console.log('Status:', res.statusCode);
        }
    });
}).on('error', function (err) {
      console.log('Error:', err);
});

}

另一个端点使用了 gzip 加密。但是这个端点没有。所以我只是将 accept-encoding 设置为空 _headers["accept-encoding"] = ""。令人困惑的是,即使编码错误,邮递员也会显示正确的响应。
