在调用http适配器程序时,会弹出一个带有ProcedureName,Signature和Paramaters的对话框,当我输入两个字符串类型参数后点击Run按钮时,我得到" Class Cast:java.lang.String不能施放到org.mozilla.javascript.Scriptable"错误。
仅供参考,我使用worklight应用程序框架数据对象编辑器创建了一个worklight适配器(自动生成.xml和impl.js文件)
impl.js文件
function CurrencyConvertor_ConversionRate(params, headers){
var soapEnvNS;
soapEnvNS = 'http://schemas.xmlsoap.org/soap/envelope/';
var request = buildBody(params, 'xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://www.webserviceX.NET/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" ', soapEnvNS);
return invokeWebService(request, headers);
}
function buildBody(params, namespaces, soapEnvNS){
var body =
'<soap:Envelope xmlns:soap="' + soapEnvNS + '">\n' +
'<soap:Body>\n';
body = jsonToXml(params, body, namespaces);
body +=
'</soap:Body>\n' +
'</soap:Envelope>\n';
return body;
}
function getAttributes(jsonObj) {
var attrStr = '';
for(var attr in jsonObj) {
var val = jsonObj[attr];
if (attr.charAt(0) == '@') {
attrStr += ' ' + attr.substring(1);
attrStr += '="' + val + '"';
}
}
return attrStr;
}
function jsonToXml(jsonObj, xmlStr, namespaces) {
var toAppend = '';
for(var attr in jsonObj) {
var val = jsonObj[attr];
if (attr.charAt(0) != '@') {
toAppend += "<" + attr;
if (typeof val === 'object') {
toAppend += getAttributes(val);
if (namespaces != null)
toAppend += ' ' + namespaces;
toAppend += ">\n";
toAppend = jsonToXml(val, toAppend);
}
else {
toAppend += ">" + val;
}
toAppend += "</" + attr + ">\n";
}
}
return xmlStr += toAppend;
}
function invokeWebService(body, headers){
var input = {
method : 'post',
returnedContentType : 'xml',
path : '/CurrencyConvertor.asmx',
body: {
content : body.toString(),
contentType : 'text/xml; charset=utf-8'
}
};
//Adding custom HTTP headers if they were provided as parameter to the procedure call
headers && (input['headers'] = headers);
return WL.Server.invokeHttp(input);
}
答案 0 :(得分:1)
该错误表示代码中某处存在无效的JSON对象。
使用body.toString()
将主体转换为String时,很可能会出现此错误
因为toString
将返回[object Object]
,这是无效的JSON对象值(既不是有效的字符串也不是有效的数组)
使用json.stringify(body)
代替它,它应该做你想做的事。
此外,尝试添加一些日志行以便于跟踪错误
