Question

我正在将我的应用程序从MFP V 7.1迁移到MFP V 8.0。我有以下场景，我正在构建一个数据对象，并使用以下代码从我的客户端向MFP适配器发送请求：

function SearchData(username,name,city){
    this.username = username;
    this.name = name;
    this.city = city;
}


searchData(){
    var searchData = new SearchData(getUserId(),name,city);
    var dataRequest = new WLResourceRequest('/adapters/MyAdapterName/searchEmployer', WLResourceRequest.GET);
    alert('there');
    dataRequest.send(searchData).then(
            function(response){
                console.log('response --> ' + response);
            },
            function(){
                console.log('error response --> ' );
            }
    );
}

以下是我的java脚本适配器中编写的代码：

function searchData(searchData){
    try{
        WL.Logger.info("Inside searchData() method.");
        var input = {
                method              : 'post',
                returnedContentType : 'json',
                path                : 'rest/search',
                body                : {
                    contentType : 'application/json;charset=utf-8',
                    content     : JSON.stringify(searchData)
                }

        };
        var response = MFP.Server.invokeHttp(input);
        return response;
    }catch(exception){
        WL.Logger.error("Inside searchData() method :: " + exception.message);
        throw exception;
    }
}

每当我调用此方法时，都会调用失败函数。我还尝试使用sendFormParameters方法发送请求，但它在错误后返回打印：

worklight.js:9342 Uncaught Error: Invalid invocation of method WLResourceRequest.sendFormParameters; Form value must be a simple type.

当您传递的对象包含嵌套对象或类型为函数时，会出现此问题。

在您的情况下，您有多个具有相同名称searchData，SearchData的变量/函数。我建议您将名称更改为更具描述性。

我尝试了以下内容并成功运行

function SearchData(username,name,city){
    this.username = username;
    this.name = name;
    this.city = city;
}


function search(){
    var data = new SearchData(getUserId(), name, city);
    var request = new WLResourceRequest('/adapters/MyAdapterName/searchEmployer', WLResourceRequest.GET);
    request.send(searchData).then(function(response){
      console.log('response --> ', response);
    }, function(error){
      console.log('error response --> ', error);
    });
}

如果您在运行上述代码后仍遇到问题，请与您的项目共享链接或添加更多代码段。

<强> UDPATE：

对于Javascript适配器，通过GET变量params接收参数，params是一个参数数组。

因此，您需要在客户端更新代码，如下所示：

function search(){
    var data = new SearchData(getUserId(), name, city);
    var request = new WLResourceRequest('/adapters/MyAdapterName/searchEmployer', WLResourceRequest.GET);
    request.setQueryParameter("params", [JSON.stringify(data)]);
    request.send().then(function(response){
      console.log('response --> ', response);
    }, function(error){
      console.log('error response --> ', error);
    });
}

由于传递给适配器的数据是一种刺痛，您需要更新适配器程序以反映该情况，即删除JSON.stringify

function searchData(payload){
    try{
        WL.Logger.info("Inside searchData() method.");
        var input = {
                method              : 'post',
                returnedContentType : 'json',
                path                : 'rest/search',
                body                : {
                    contentType : 'application/json;charset=utf-8',
                    content     : payload
                }

        };
        var response = MFP.Server.invokeHttp(input);
        return response;
    }catch(exception){
        WL.Logger.error("Inside searchData() method :: " + exception.message);
        throw exception;
    }
}
