在Worklight适配器中更改HTTP URL [英] Change HTTP URL in Worklight adapter

问题描述

我需要为worklight创建一个HTTP适配器，但必须通过参数以编程方式提供url。

I need to create an HTTP adapter for worklight but the url must be programmatically provided via a parameter.

1）我能够传递用户/密码但是不是网址。有没有办法做到这一点？

1) I was able to pass the user/password but not the url. Is there a way to do that?

我也尝试创建自己的java适配器来调用REST API，它在我测试适配器时有效，但似乎是我的响应不是工作灯的预期格式。我收到此错误：

I also try to create my own java adapter to call the REST API, It works when I test the adapter but it seems my response is not in the expected format for worklight. I got this error:

2）BAD_PARAMETER_EXPECTED_DOCUMENT_OR_ARRAY_OF_DOCUMENT。

2) BAD_PARAMETER_EXPECTED_DOCUMENT_OR_ARRAY_OF_DOCUMENT.

我的Java适配器返回JSONArtifact（JSONObject）但它似乎worklight希望将它嵌入到另一个JSONObject中，例如{array：{...}}。
有没有办法将JSONObject转换为worklight所期望的格式。

my Java adapter returns a JSONArtifact (JSONObject) but it seems that worklight want this to be embedded in another JSONObject such as { "array":{...}}. Is there a way to convert a JSONObject to the format expected by worklight.

    import org.apache.wink.json4j.JSON;
    import org.apache.wink.json4j.JSONArtifact;
    import org.apache.wink.json4j.JSONException;

private Header headerUserAgent = new Header("User-Agent", "Mozilla");
private Header headerAccept = new Header("Accept", "application/json");

private String hostName;
private String baseURL;

protected MyHttpClient(String userName, String userPassword, String hostName, String baseURL ) {
    super();
    Credentials defaultcreds = new UsernamePasswordCredentials(userName,
            userPassword);
    this.getState().setCredentials(AuthScope.ANY, defaultcreds);
    this.hostName = hostName;
    this.baseURL = baseURL;
}


private GetMethod getGetMethod(String url) throws URIException {
    GetMethod httpMethod = new GetMethod(new HttpsURL("https://"+hostName+baseURL+url).getEscapedURI());
    addCommonHeaders(httpMethod);
    return httpMethod;
}
private JSONArtifact getResponseAsJSONObject(InputStream inputStream) throws IOException {
    InputStreamReader reader = new InputStreamReader(inputStream);
    try {
        JSONArtifact json = JSON.parse(reader);
        return json;
    } catch (NullPointerException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return null;
         }

适配器：

    function getResponse(user,password) {
        var client = new com.itdove.mypackage.MyHttpClient(user,password,"myurl","mybaseurl");
        return {
            array : client.executeGet("mypath")
        };
    }

它适用于此但此解决方案不提供服务URL作为参数：

it works with this but this solution doesn't provide the service url as parameter:

    function getResponseAdapters(path, username, password) {

        var input = {
            method : 'get',
            returnedContentType : 'json',
            headers: {
                'User-Agent':'Mozilla',
                'Authorization': 'Basic '+Base64.encode(username+':'+password),
            }  , 
            path : '/resources/' + path
        };

        return WL.Server.invokeHttp(input);
    }

    function getResponse(username, password) {
        return getMySCAWSAdapters(path, username, password);
    }

收藏

                vAPPArrayAdapterOptions = {
                    name: 'myResponseAdapter',
                    replace: '',
                    remove: '',
                    add: '',
                    load: {
                        procedure: 'getResponse',
                        params: ["user","password"],
                        key: 'array'
                    },
                    accept: function (data) {
                        return (data.status === 200);
                    }
                },

    ...
                    vAPPArray = wlJsonStore.initCollection(
                            "vAPPArray",
                            vAPPArraySearchFields,
                            {adapter: vAPPArrayAdapterOptions, 
                            onSuccess: initCollectionSuccessCallback, 
                            onFailure: initCollectionFailureCallback, 
                            load:true});

非常感谢

Many Thanks Dominique

推荐答案

找到解决方案：

首先，我使用的是apache wink JSONArtifact而不是com.ibm.json.java.JSONArtifact！

First, I was using apache wink JSONArtifact instead of the com.ibm.json.java.JSONArtifact!

其次我修改了我的收集器实现方法，如下所示添加状态（不确定是否需要）

Secondly I modified my collector implement method as follow to add the status (not sure if it is needed or not)

function getResponse(user,password,hostname) {
    var client = new com.itdove.mypackage.IWDHttpClient(user,password,hostname,"mypath");
    return {
        array :client.executeGet("mymethod"),
        statusCode: client.getStatusCode(),
        statusReason: client.getStatusReason()
    };
}

myCollector.js中的

我在调用initCollection之前设置了用户，密码和主机名。

in myCollector.js I set the user, password, hostname as follow before calling my initCollection.

        params = [ settings.json.user, settings.json.password, settings.json.hostname ];
        myAdapterOptions.load["params"] = params;
