问题描述
我有一个本地json文件，并使用Bundle.main.path函数访问文件路径，但出现错误。
服务
class Service {
fileprivate var baseURL: String?
init(baseURL: String) {
self.baseURL = baseURL
}
func getAllData() {
AF.request(self.baseURL!,method: .get,parameters: nil,encoding: URLEncoding.default,headers: nil,interceptor: nil,requestModifier: .none).response { (responseData) in
guard let data = responseData.data else { return }
do {
let packages = try JSONDecoder().decode(Package.self,from: data)
print(packages)
} catch let error {
print(error.localizedDescription)
}
}
}
}
视图控制器
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
guard let url = Bundle.main.path(forResource: "packageList",ofType: "json") else { return }
let service = Service(baseURL: url)
service.getAllData()
}
解决方法
您正在传递路径（一个<?php
if ( !defined( '_PS_ADMIN_DIR_' ) ) {
define( '_PS_ADMIN_DIR_',getcwd() );
}
include( _PS_ADMIN_DIR_ . '/../config/config.inc.php' );
addProduct(
'1234567891234',// Product EAN13
'Stackoverflow',// Product reference
'Crezzur',// Product name
5,// Product quantity
'Code by Crezzur (https://crezzur.com)',// Product description
array( // Product features (array)
array( "name" => "Color","value" => "Red" ),array( "name" => "Height","value" => "200cm" ),),'999.95',// Product price
'https://i.imgur.com/yOp1xt3.jpg',// Product image
1,// Product default category
array(1,5) // All categorys for product (array)
);
function addProduct( $ean13,$ref,$name,$qty,$text,$features,$price,$imgUrl,$catDef,$catAll ) {
$product = new Product(); // Create new product in prestashop
$product->ean13 = $ean13;
$product->reference = $ref;
$product->name = createMultiLangField( $name );
$product->description = htmlspecialchars($text);
//$product->link_rewrite = createMultiLangField($linkrewrite);
$product->id_category_default = $catDef;
$product->redirect_type = '301';
$product->price = $price;
$product->quantity = $qty;
$product->minimal_quantity = 1;
$product->show_price = 1;
$product->on_sale = 0;
$product->online_only = 0;
$product->meta_description = '';
$product->add();
$product->addToCategories($catAll);
// Insert "feature name" and "feature value"
if ( is_array( $features ) ) {
foreach ( $features as $feature ) {
$attributeName = $feature[ 'name' ];
$attributeValue = $feature[ 'value' ];
// 1. Check if 'feature name' exist already in database
$FeatureNameId = Db::getInstance()->getValue( 'SELECT id_feature FROM ' . _DB_PREFIX_ . 'feature_lang WHERE name = "' . pSQL( $attributeName ) . '"' );
// If 'feature name' does not exist,insert new.
if ( empty( $getFeatureName ) ) {
Db::getInstance()->execute( 'INSERT INTO `' . _DB_PREFIX_ . 'feature` (`id_feature`,`position`) VALUES (0,0)' );
$FeatureNameId = Db::getInstance()->Insert_ID(); // Get id of "feature name" for insert in product
Db::getInstance()->execute( 'INSERT INTO `' . _DB_PREFIX_ . 'feature_shop` (`id_feature`,`id_shop`) VALUES (' . $FeatureNameId . ',1)' );
Db::getInstance()->execute( 'INSERT INTO `' . _DB_PREFIX_ . 'feature_lang` (`id_feature`,`id_lang`,`name`) VALUES (' . $FeatureNameId . ',' . Context::getContext()->language->id . ',"' . pSQL( $attributeName ) . '")' );
}
// 1. Check if 'feature value name' exist already in database
$FeatureValueId = Db::getInstance()->getValue( 'SELECT id_feature_value FROM webshop_feature_value WHERE id_feature_value IN (SELECT id_feature_value FROM webshop_feature_value_lang WHERE value = "' . pSQL( $attributeValue ) . '") AND id_feature = ' . $FeatureNameId );
// If 'feature value name' does not exist,insert new.
if ( empty( $FeatureValueId ) ) {
Db::getInstance()->execute( 'INSERT INTO `' . _DB_PREFIX_ . 'feature_value` (`id_feature_value`,`id_feature`,`custom`) VALUES (0,' . $FeatureNameId . ',0)' );
$FeatureValueId = Db::getInstance()->Insert_ID();

}
}
$shops = Shop::getShops( true,null,true );
$image = new Image();
$image->id_product = $product->id;
$image->position = Image::getHighestPosition( $product->id ) + 1;
$image->cover = true;
if ( ( $image->validateFields( false,true ) ) === true && ( $image->validateFieldsLang( false,true ) ) === true && $image->add() ) {
$image->associateTo( $shops );
if ( !uploadImage( $product->id,$image->id,$imgUrl ) ) {
$image->delete();
}
}
echo 'Product added successfully (ID: ' . $product->id . ')';
}
function uploadImage( $id_entity,$id_image = null,$imgUrl ) {
$tmpfile = tempnam( _PS_TMP_IMG_DIR_,'ps_import' );
$watermark_types = explode( ',',Configuration::get( 'WATERMARK_TYPES' ) );
$image_obj = new Image( $id_image );
$path = $image_obj->getPathForCreation();
$imgUrl = str_replace( ' ','%20',trim( $imgUrl ) );
// Evaluate the memory required to resize the image: if it's too much,you can't resize it.
if ( !ImageManager::checkImageMemoryLimit( $imgUrl ) )
return false;
if ( @copy( $imgUrl,$tmpfile ) ) {
ImageManager::resize( $tmpfile,$path . '.jpg' );
$images_types = ImageType::getImagesTypes( 'products' );
foreach ( $images_types as $image_type ) {
ImageManager::resize( $tmpfile,$path . '-' . stripslashes( $image_type[ 'name' ] ) . '.jpg',$image_type[ 'width' ],$image_type[ 'height' ] );
if ( in_array( $image_type[ 'id_image_type' ],$watermark_types ) ) {
Hook::exec( 'actionWatermark',array( 'id_image' => $id_image,'id_product' => $id_entity ) );
}
}
} else {
unlink( $tmpfile );
return false;
}
unlink( $tmpfile );
return true;
}
function createMultiLangField( $field ) {
$res = array();
foreach ( Language::getIDs( false ) as $id_lang ) {
$res[ $id_lang ] = $field;
}
return $res;
}
，因此String上的URLConvertible会调用一个String，这最终将是无效的，但要使其起作用，它需要改为调用URL(string: path)。
URL(fileURLWithPath: path)=>
guard let url = Bundle.main.path(forResource: "packageList",ofType: "json") else { return }
OR
guard let url = Bundle.main.url(forResource: "packageList",withExtension: "json") else { return }
但是我更喜欢第一个解决方案，让我们避免手动转换。
