反映本机图像URI不显示

Question

在ListView中渲染一组行组件时，我的uri图像似乎根本没有显示出来。我在反应模块中包含了Image。我的自定义组件如下：

var url = rowData.mediaGroups[0].contents[0].url; 
            if (url.indexOf('w=150') > -1)
            {
                url.replace("w=150", "w=500");
            }
            return <ArticlePreview
                category={rowData.categories[0]}
                key={sectionID}
                heartText={'2.9k'}
                categoryPress={this.onCategoryDetailsPress}
                selected={false}
                source={{ uri: url }}
                text={rowData.title.toLowerCase().replace('&nbsp;','')}
                onPress={this.onArticleDetailsPress} />

该组件具有多个属性，并在我的应用程序中使用（并在其中使用链接图像）。但由于某种原因，该组件刚刚停止在应用程序中工作uri图像。不知道该怎么办。以下是组件本身的代码：

//component for article preview touchable image
/* will require the following
- rss feed and api
- user's keyword interests from parse In home.js
- parse db needs to be augmented to include what they heart
- parse db needs to be augmented to include what they press on (like google news)
*/
var React = require('react-native');
var {
  View, 
  StyleSheet, 
  Text, 
  Image, 
  TouchableHighlight, 
} = React;

//dimensions
var Dimensions = require('Dimensions');
var window = Dimensions.get('window');
var ImageButton = require('../../common/imageButton');
var KeywordBox = require('../../authentication/onboarding/keyword-box');

//additional libraries

module.exports = React.createClass({
  //onPress function that triggers when button pressed
  //this.props.text is property that can be dynamically filled within button 
  /* following props:
    - source={this.props.source}
    - onPress={this.props.onPress}
    - {this.props.text}
    - {this.props.heartText}
    - key={this.props.key} 
    - text={this.props.category} 
    - this.props.selected
  */
  render: function() {
    return (
      <TouchableHighlight 
        underlayColor={'transparent'}
        onPress={this.props.onPress} >
          <Image source={this.props.source} style={[styles.articlePreview, this.border('red')]}>

    //will move this function to a general module

      }
