Question

我正在尝试开发一个wirecloud运算符，但我不知道如何在config.xml上包含一个javascript库（即jquery），除了main.js文件。我尝试在config.xml中包含jquery库，就像main.js一样，使用不同的wire：index，但它不起作用。

有没有办法包含第二个JS库？

Answer 1

是的，您可以在运营商中拥有多个javascript文件。我认为您的问题与RDF语法有关，这有点奇怪。无论如何，以下代码片段是如何使用RDF / XML包含jquery和main.js文件的示例：

<usdl:utilizedResource>
  <usdl:Resource rdf:about="js/jquery.min.js">
    <wire:index>0</wire:index>
  </usdl:Resource>
</usdl:utilizedResource>
<usdl:utilizedResource>
  <usdl:Resource rdf:about="js/main.js">
    <wire:index>1</wire:index>
  </usdl:Resource>
</usdl:utilizedResource>

或者，如果您在FIWARE Lab使用Mashup门户，则可以使用将在WireCloud 0.7.0上可用的新XML格式（目前Mashup门户正在运行该版本的候选版本）。这是新格式的一个示例：

<?xml version='1.0' encoding='UTF-8'?>
<operator xmlns="http://wirecloud.conwet.fi.upm.es/ns/macdescription/1" vendor="CoNWeT" name="ngsi-source" version="3.0">
    <details>

    </requirements>
    <preferences>
        <preference name="ngsi_server" type="text" label="NGSI server URL" description="URL of the Orion Context Broker to use for retrieving entity information" default="http://orion.lab.fi-ware.org:10026/"/>

        <preference name="ngsi_entities" type="text" label="NGSI entity types" description="A comma separated list of entity types to use for filtering entities from the Orion Context broker. Thies field cannot be empty." default="Node, AMMS, Regulator"/>
        <preference name="ngsi_id_filter" type="text" label="Id pattern" description="Id pattern for filtering entities. This preference can be empty, in that case, entities won't be filtered by id." default=""/>
        <preference name="ngsi_update_attributes" type="text" label="Monitored NGSI Attributes" description="Attributes to monitor for updates. Currently, the Orion Context Broker requires a list of attributes to monitor for changes, so this field cannot be empty." default="Latitud, Longitud, presence, batteryCharge, illuminance, ActivePower, ReactivePower, electricPotential, electricalCurrent"/>
    </preferences>
    <wiring>
        <outputendpoint name="entityOutput" type="text" label="Provide entity" description="Every change over each entity fires an event" friendcode="entity"/>
    </wiring>
    <scripts>
        <script src="js/other.dependency.js"/>
        <script src="js/main.js"/>
    </scripts>

</operator>

最后，我在wirecloud运算符上使用RDF / XML包含其他JS文件。首先，我在config.xml文件中使用以下代码：

<usdl-core:utilizedResource rdf:about="js/jquery-1.10.2.min.js">
    <wire:index>0</wire:index>
</usdl-core:utilizedResource>

<usdl-core:utilizedResource rdf:about="js/main.js">
    <wire:index>1</wire:index>
</usdl-core:utilizedResource>

此外，包含的JS文件必须声明如下：

<wire:Operator rdf:about="http://wirecloud.conwet.fi.upm.es/ns/widget#Operator">
    ...
    <usdl-core:utilizedResource rdf:resource="js/jquery-1.10.2.min.js"/>
    <usdl-core:utilizedResource rdf:resource="js/main.js"/>
    ....
</wire:Operator>
