这两周开始学习node，打算做一个天气采集程序，用soap调用接口的时候报错：请高人指点下迷津 TypeError: Cannot call method ‘setSOAPAction’ of undefined at C:\Documents and Settings\wuyfl\webService.js:5:11 at C:\Documents and Settings\wuyfl\node_modules\soap\lib\soap.js:49:5 at C:\Documents and Settings\wuyfl\node_modules\soap\lib\soap.js:33:16 at C:\Documents and Settings\wuyfl\node_modules\soap\lib\wsdl.js:1754:9 at Request._callback (C:\Documents and Settings\wuyfl\node_modules\soap\lib\http.js:49:7) at self.callback (C:\Documents and Settings\wuyfl\node_modules\soap\node_modules\request\request.js:373:22) at Request.emit (events.js:95:17) at Request.onRequestError (C:\Documents and Settings\wuyfl\node_modules\soap\node_modules\request\request.js:971:8) at ClientRequest.emit (events.js:95:17) at Socket.socketErrorListener (http.js:1551:9)

下面代码： var soap = require(‘soap’); var url = 'http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl’; var args = { byProvinceName: '北京’}; soap.createClient(url, function(err, client) { client.setSOAPAction(“http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupport”); client.getSupportCity(args, function(err, result) { if (err) { throw err; } console.log(result);

});

});
