uni.chooseImage 相机相册选择图片弹框国际化

自己封装的一个实现选择图片弹框国际化的方法，返回的格式与 uni.chooseImage 相同，因此可以把 uni.chooseImage 替换掉，在main.js挂到了Vue原型上：

/** 封装国际化选择图片  
 * @param {Object} self 组件中的 this  
 * @param {Object} params 配置参数  
 */  
Vue.prototype.selectImage = (self, params = {}) => {  
    let count = params.count || 9;                                  // 数量  
    let sizeType = params.sizeType || ['original', 'compressed'];   // 原图和压缩图  
    let sourceType = params.sourceType || ['camera', 'album'];      // 相册和相机  
    let success = params.success || function success(){};           // 成功回调  
    let fail = params.fail || function fail(){};                    // 失败回调  
    let option = {  
        cancel: self.$t('prompt.btn2'),          // i18n取消文字  
        buttons: [{  
                title: self.$t('prompt.imgBtn1') // i18n相机文字    
            },  
            {  
                title: self.$t('prompt.imgBtn2') // i18n相册文字    
            }  
        ]  
    };
