如何将参数传递给MobileFirst HTTP适配器

Question

我需要运行HTTP适配器来访问SOAP WSDL服务。它有2个字段userid和password。

我已经通过发现后端服务自动生成适配器。任何人都可以指导我如何从适配器初始传递值来访问服务？

要调用适配器，并通过你需要调用WL.Client.invokeProcedure你的具体情况的参数，你可以使用

var invocationData = { 
    adapter: 'YOUR_ADAPTER_NAME', 
    procedure: 'userlogin_ep_process', 
    parameters: { 
     process: { 
      username: 'YOUR_USERNAME', 
      userpwd: 'YOUR_PASSWORD' 
     } 
    } 
}; 
WL.Client.invokeProcedure(invocationData, { 
    onSuccess: yourSuccessFunction, 
    onFailure: yourFailureFunction 
});
