Soap MobileFirst 6.3调用后端服务创建的适配器过程

我很难想出如何调用MobileFirst使用Discover后端服务功能为我创建的适配器

我创建了适配器，但没有使用以下代码尝试调用它：

function callService(){
    alert("Calling into Backend");
    var options = {
            onSuccess : loadSuccess,
            onFailure : loadFailure,
            invocationContext: {}
        };

    var params = {"itemRequiredReference":10};

    var invocationData = {
            adapter : 'SoapAdapter1',
            procedure : 'inquireSingleService_inquireSingle',
            parameters : [params]
        };

    WL.Client.invokeProcedure(invocationData, options);
}

但这似乎不起作用。我得到一个错误：

{"status":200,"invocationContext":{},"invocationResult":{"statusCode":500,"errors":[],"isSuccessful":true,"Envelope":{"SOAP-ENV":"http://schemas.xmlsoap.org/soap/envelope/","Body":{"Fault":{"":"","detail":{"CICSFault":{"CDATA":"DFHPI1010 02/02/2015 22:11:37 GENAPPA1 CPIH 00518 XML generation failed.

对于（变量i=0；i对于（var i=0；i我终于在这里找到了一个有用的文档页面：

解决方案是将变量参数设置为：

var params = {"inquireSingleRequest": {"itemRequiredReference": "10"}}

    var invocationData = {
            adapter : 'SoapAdapter1',
            procedure : 'inquireSingleService_inquireSingle',
            parameters : [params]
        };

这使它能够完美地工作。
