node.js - 使用 Node.js 数据创建 POST http.request 的问题在 FormValue 而不是 Body 中传递

Question

我尝试执行一个 http.request POST，我的数据被传递给 FormValue 而不是 Body。这是我在 Node.js http 调用中的第一个实验，所以如果问题微不足道，我深表歉意。我将调用传递给服务器，并在代码末尾获得了数据。

function doHttpApiCall(session,callback) {
    var http = require('http');   
    var isEndedOk;
    var outValue = '';
    var postData = JSON.stringify({
            grant_type: 'client_credentials',
            scope: 'OOB',
            my_id: 'my_id_value'
        });



    var postOptions = {
                host: 'dummyapisite.com',
                path: '/t/litf9-1571295453/post',
                method: 'POST',
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded',
                    'Content-Length': postData.length
                }
    };

   // Set up the request
   var post_req = http.request(postOptions, function(res) {
      var statusCode = res.statusCode;
      let error;
      if (statusCode !== 200) {
        error = new Error('Request Failed.\n' +
                          `Status Code: ${statusCode}`);
      }
      res.setEncoding('utf8');
      let rawData = '';
      res.on('data', (chunk) => { rawData += chunk; });
      res.on('end', () => {
        try {
          const  parsedData = rawData;
          if (error) {
                isEndedOk = false;
                console.error(error.message);
                console.error('Response Content=' + String(parsedData));
                res.resume();
          } else {
                isEndedOk = true;
                console.log('Response Content=' + String(parsedData));
          }         
          callback(session.attributes,
                callBack_doHttpApiCall(outValue, statusCode, session, callback, isEndedOk));
        } catch (e) {
          console.error(e.message);
        }
      });
    }).on('error', (e) => {
      console.error(`Got error: ${e.message}`);
    });
    post_req.write(postData);
    post_req.end();
}

这是服务器得到的结果，数据不在正确的地方。

问题是您发送的是 JSON 正文，但是您发送的 Content-Type 是:application/x-www-form -urlencoded，所以改成application/json

您要发布到的服务器将值放入 FormValues 因为您告诉他们您正在发送表单 (x-www-form-urlencoded)

var postOptions = {
    host: 'dummyapisite.com',
    path: '/t/litf9-1571295453/post',
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
        'Content-Length': postData.length
    }
};
