node soap模块

官方文档：https://www.npmjs.com/package/soap

Install

npm install soap

方法

• soap.createClient(url[, options], callback)

  var soap = require('soap');
  var url = 'http://example.com/wsdl?wsdl';
  var args = {name: 'value'};
  soap.createClient(url, function(err, client) {
      client.***(args, function(err, result) {
          console.log(result);
      });
  });

• soap.createClientAsync(url[, options])

  var soap = require('soap');
  var url = 'http://example.com/wsdl?wsdl';
  var args = {name: 'value'};
  soap.createClientAsync(url).then((client) => {
    return client.['***' + 'Async'](args);
  }).then((result) => {
    console.log(result);
  });

options参数（有以下几个）：

• endpoint: to override the SOAP service's host specified in the .wsdl file.（不懂）
• envelopeKey: to set specific key instead of
  .（不懂）
• preserveWhitespace: 保留text and cdata前后的空格
• escapeXML: 将SOAP信息中特殊的XML符号escape编码处理，例如&, >, <等，属性值默认为true
• suppressStack: suppress the full stack trace for error messages.
• returnFault: 对于错误请求，返回一个无效的XMLSOAP，默认为false
• forceSoap12Headers: 将消息头强制设置成SOAP1.2
• httpClient: to provide your own http client that implements request(rurl, data, callback, exheaders, exoptions).（提供你自己的http请求。。。不懂）
• request: 重写request模块.
• wsdl_headers: 在WSDL请求中自定义发送的HTTP头.
• wsdl_options: 在WSDL请求中为request模块自定义选项.
• disableCache: 不缓存WSDL文件，每次都重新请求.
• overridePromiseSuffix: 如果你的WSDL操作包含Async后缀，你需要去重写一个特定的后缀，选项默认为Async
• normalizeNames: if your wsdl operations contains names with non identifier characters ([^a-z$_0-9]), replace them with _. Note: if using this option, clients using wsdls with two operations like soap:method and soap-method will be overwritten. Then, use bracket notation instead (client['soap:method']()).（不懂）
• namespaceArrayElements: provides support for nonstandard array semantics. If true, JSON arrays of the form {list: [{elem: 1}, {elem: 2}]} are marshalled into xml as 1 2. If false, marshalls into 1 2 . Default: true.（不懂）
  !!!0.10.X以上版本的node，要增加这个参数{connection: 'keep-alive'}避免截断了过长的请求
