在 node.js 中发送带有 XML 数据的 POST 请求：错误 400，"The request sent by the client was syntactically incorrect"

Question

我正在尝试使用 node.js 重现 this Python POST 请求（已验证有效）。这是一个相当简单的 POST 请求发送和接收 XML 数据。

但是，尽管我的 XML 有效（已验证）并直接取自 Python 示例，但我收到 The request sent by the client was syntactically incorrect 错误。我做错了什么？

我的代码（可重现）：

// DOC:
// https://wiki.solargis.com/display/public/WS+API+technical+documentation#WSAPItechnicaldocumentation-DatadeliveryWebservice(APIforgettingtimeseriesdata)
// https://nodejs.org/api/http.html#http_http_request_options_callback
// https://nodejs.org/api/http.html#http_request_write_chunk_encoding_callback
// https://nodejs.org/api/https.html

let https = require('https');

const api_key = 'demo';

var request = '<?xml version="1.0" encoding="UTF-8"?>' +
'<ws:dataDeliveryRequest dateFrom="2014-04-28" dateTo="2014-04-28" ' +
    'xmlns="http://geomodel.eu/schema/data/request" ' +
    'xmlns:ws="http://geomodel.eu/schema/ws/data" ' +
    'xmlns:geo="http://geomodel.eu/schema/common/geo" ' +
    'xmlns:pv="http://geomodel.eu/schema/common/pv" ' +
    'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">' +
        '<site id="demo_site" name="Demo site" lat="48.61259" lng="20.827079"></site>' +
        '<processing key="GHI" summarization="HOURLY" terrainShading="true"></processing>' +
'</ws:dataDeliveryRequest>';

var request_utf8 = Buffer.from(request, 'utf-8');

let options = {
  host: 'solargis.info',
  path: `/ws/rest/pvplanner/calculate?key=${api_key}`,
  headers: {
      'Content-Type': 'application/xml',
    //   'Content-Length': Buffer.byteLength(request),
    //   'Transfer-Encoding': 'chunked', //See https://nodejs.org/api/http.html#http_request_write_chunk_encoding_callback
    },
  method: 'POST',
};

const req = https.request(options, (res) => {
    console.log(`STATUS: ${res.statusCode}`);
    console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
    res.setEncoding('utf8');
    res.on('data', (chunk) => {
        console.log(`BODY: ${chunk}`);
    });
    res.on('end', () => {
        console.log('No more data in response.');
    });
});

req.on('error', (e) => {
    console.error(`problem with request: ${e.message}`);
});

// Write data to request body
req.write(request_utf8);
req.end();

输出：

No more data in response.

发现问题。我从错误的示例中将请求发布到 URL！正确的 path 行是 path: `/ws/rest/datadelivery/request?key=${api_key}`,.
