以下代碼是 Postman 的摘錄，我在其中得到了回應。由于某種原因，NodeJS 版本似乎沒有運行并給出“Socket hang up”錯誤，而 python 版本運行良好。兩個代碼都粘貼在下面：
const obj = {
asset: [
{
age: "33",
existingDisease: false,
gender: "MALE",
id: "883a8cb5446f4d6780db2e59bdf4ee35",
proposerRelationShip: "SELF",
used: false,
},
],
cover: [],
pinCode: "122001",
quoteId: "7637d7ff982145569fbfa604e3b74485",
sumInsured: "700000",
term: { unit: "YEAR", value: "1" },
};
const strObj = JSON.stringify(obj);
var options = {
method: "POST",
url: "https://sa.navi.com/v3/premium?paymentMode=SUBSCRIPTION",
headers: {
appversion: "2.2.4",
appversioncode: "92",

},
body: strObj,
};
console.log("Going to trigger API");
console.log(options);
request(options, function (error, response) {
if (error) throw new Error(error);
console.log(response.body);
});
給出錯誤：
錯誤：錯誤：套接字掛起
雖然 Python 中的相同代碼有效：

uj5u.com熱心網友回復：
你content-length錯了（當你的有效載荷 JSON 的實際長度為 279 時，你傳遞了 419）。這可能意味著接收服務器仍在等待其余內容到達，它永遠不會到達，因此最終服務器超時并掛斷您（這就是您收到掛斷錯誤的原因）。
而且，你瞧，當我洗掉content-length標頭并讓請求庫自動計算它時，請求開始為我作業。
至于 python 實作，一個猜測是它覆寫了錯誤的內容長度并為您修復它。
僅供參考，該request()庫已被棄用，不建議人們使用它撰寫新代碼，因為將來它不會使用新功能進行改進。建議的替代方案串列（所有支持承諾）在這里。在該串列中我最喜歡的是got()它也支持與request()庫相同的大多數選項，但它是基于 Promise 的核心，并且有許多 API 改進，使其更易于使用（在我看來）。
而且，確實您的代碼與got()庫一起作業得很好（在洗掉不正確的content-length標頭之后）。
const got = require('got');
