node.js - 发送 RESTClient Firefox POST 并在 node.js 中尝试相同的操作

Question

我正在使用 FireFox Rest 客户端发送以下帖子:

POST /WSPublic.asmx HTTP/1.1
Content-Type: application/soap+xml; charset=utf-8
Content-Length: 462
Host: host
Connection: close

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><ContadoresTR xmlns="https://xxxxx"><Usuario>user</Usuario><Contrasena>password</Contrasena><NInstalacion>inst</NInstalacion><VersionFicheroEsperado>1</VersionFicheroEsperado></ContadoresTR></soap12:Body></soap12:Envelope>

它有效，我收到了服务器的响应。

查看 Wireshark 对话，我发现 RESTClient 首先发送以下流:

...........fe....0..S.... ..L0g....!...z.P. _....N.im3....8.q.'...6.9.....p>. .+./.
...........3.2.9./.5.
.......c........
ges.leako.com......
.................#..3t.....!...h2-14.spdy/3.1.spdy/3.http/1.1......... 

然后我尝试使用 node.js 执行相同的操作。 HTTP 客户端发送相同的帖子，但我没有收到服务器的响应。查看 Wireshark 对话，我发现第一个 HTTP 客户端流的格式与 Firefox 的 RESTClient 不同。

POST /WSPublic.asmx HTTP/1.1
Content-Type: application/soap+xml; charset=utf-8
Content-Length: 462
Host: host
Connection: close

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><ContadoresTR xmlns="https://xxxxxx"><Usuario>user</Usuario><Contrasena>password</Contrasena><NInstalacion>inst</NInstalacion><VersionFicheroEsperado>1</VersionFicheroEsperado></ContadoresTR></soap12:Body></soap12:Envelope>

这里是node.js脚本:

var http = require("http")

var body = '<?xml version="1.0" encoding="utf-8"?>'
            +'<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"' 
                     +'xmlns:xsd="http://www.w3.org/2001/XMLSchema"'
                     +'xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">'
                +'<soap12:Body>'
                    +'<ContadoresTR xmlns="https://ges.leako.com/WSPublic">'
                        +'<Usuario>xxx</Usuario>'
                        +'<Contrasena>xxx</Contrasena>'
                        +'<NInstalacion>xxx</NInstalacion>'
                        +'<VersionFicheroEsperado>x</VersionFicheroEsperado>'
                    +'</ContadoresTR>'
                +'</soap12:Body>'
            +'</soap12:Envelope>';

var postRequest = {
    host: "ges.leako.com",
    path: "/WSPublic.asmx",
    port: 443,
    method: "POST",
    headers: {
        'Content-Type': 'application/soap+xml; charset=utf-8',
        'Content-Length': Buffer.byteLength(body),
    'Connection': 'keep-alive'
    }
};

var buffer = "";

var req = http.request( postRequest, function( res )    {

   console.log( res.statusCode );
   var buffer = "";
   res.on( "data", function( data ) { buffer = buffer + data; } );
   res.on( "end", function( data ) { console.log( buffer ); } );

});

req.write( body );
req.end();

我做错了什么？为什么 Firefox 发送的 POST 格式与 Node.js HTTP 客户端不同，该格式是什么？

提前致谢。

除了“keep-alive”“Connection” header 和“Content-type” header 之外，一切似乎都很好，正如 @mithunsatheesh 在另一问题 how to post XML data in node.js http.request 中提到的那样。但我想您已经意识到了这一点，因为这两种情况下的代码都非常相似:)
