问题描述
我能够从我的适配器中的SOAP服务获得响应，但是从客户端我无法将参数传递给适配器。我可以使用 alert 显示值，但我无法将它们传递给 params 变量。任何人都可以帮忙吗？
I am able to get a response from a SOAP service in my adapter but from the client side I am having trouble passing the parameters to the adapter. I'm able to display the values using alert but I can't pass them to the params variable. Can anyone help?

// This is a SOAP adapter that was auto-generated by Worklight for invocation of specific SOAP-based services. //
// The adapter may invoke more than one service as long as they are all from the same enpdpoint (server host). //
// Each adapter procedure matches a single operation for the same endpoint server and accepts: //
// params - Serialized JSON representation of the XML-based SOAP body to be sent to the service //
// headers - Custom HTTP headers to be specified when invoking the remote service. It is a JSON object with //
// the headers names and values. E.g. { 'name1' : 'value1', 'name2' : 'value2' } //
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////

// The following mappings object was autogenerated from the XML schema of the input message to the service.
// It is being used to support a params JSON when invoking this procedure that don't specify the namespace
// prefix nor specifying whether a property is attribute or not.
//
// The 'roots' object has the list of message parts within the invocation SOAP message. Each entry has a
// mapping between the root element name and its namespace prefix and type.
// Each root object may define 'nsPrefix' and 'type'. Both are optional - If there is no need for a NS prefix
// then the 'nsPrefix' should not be specified. If the element is a simple type then the 'type' should not be
// specified.
//
// The 'types' object has a list of types each defining the children of the type and the definition of each
// child. If the child is a complext type, the 'type' property has a reference to the child type definition.
// Each child object may define:
// 'nsPrefix' (optional) - Holds the namespace prefix to be attached to the element. If there is no need for
// a NS prefix then the 'nsPrefix' should not be specified.
// 'type' (optional) - If the element is a simple type then the 'type' should not be specified. If it is an
// attribute then 'type' should have the value of '@'. Otherwise the value of 'type' is a reference to the
// type definition within the 'types' object.

推荐答案
问题在于您将字段值传递给 params 对象的方式。如果用引号括起javascript表达式，那么它不再是表达式，而是字符串。
The problem lies in the way you are passing the field values to the the params object. If you wrap a javascript expression in quotes then it's not longer an expression, it's a string.
您应该更改验证函数，如下所示：
You should change your validate function as follow:
function validate(){
var username = $('#username').val();
var password = $('#userpwd').val();
busyIndicator.show();
var params = {
"process": {
"username": username,
"userpwd": password
}
};
var invocationData = {
adapter : 'SoapAdapter1',
procedure : 'userlogin_ep_process',
parameters : [params]
};
WL.Client.invokeProcedure(invocationData,{
onSuccess : loadFeedsSuccess,
onFailure : loadFeedsFailure
});
}
PS：我同意@Idan你应该只保留一个问题因为另一个问题是针对同一问题的。
PS: I agree with @Idan you should keep only one question because the other questions is for same issue.
