我需要开发 Marketplace API 来获取订单并用 PHP 将发货邮寄到沃尔玛。他们的代码库/帮助示例以 Java 提供。我不擅长Java。

需要帮助理解/用 PHP 编码。这是Java中的代码。链接到 API 开发人员指南 https://developer.walmartapis.com/#self-written-code-expert

此应用程序位于 Cpanel 服务器上。

import org.apache.commons.codec.binary.Base64;
import java.security.KeyFactory;
import java.security.PrivateKey;
import java.security.Signature;
import java.security.spec.PKCS8EncodedKeySpec;

public class SHA256WithRSAAlgo {
private static String consumerId = "b68d2a72....";   // Trimmed for security reason
private static String baseUrl = "https://marketplace.walmartapis.com/v2/feeds";
private static String privateEncodedStr = "MIICeAIBADANBgkqhkiG9w0BAQEFAA......";       //Trimmed for security reasons
public static void main(String[] args) {
    String httpMethod = "GET";
    String timestamp = String.valueOf(System.currentTimeMillis());
    String stringToSign = consumerId + "\n" +
                            baseUrl + "\n" +
                            httpMethod + "\n" +
                            timestamp + "\n";
    String signedString = SHA256WithRSAAlgo.signData(stringToSign, privateEncodedStr);
    System.out.println("Signed String: " + signedString);
}
public static String signData(String stringToBeSigned, String encodedPrivateKey) {
    String signatureString = null;
    try {
        byte[] encodedKeyBytes = Base64.decodeBase64(encodedPrivateKey);
        PKCS8EncodedKeySpec privSpec = new PKCS8EncodedKeySpec(encodedKeyBytes);
        KeyFactory kf = KeyFactory.getInstance("RSA");
        PrivateKey myPrivateKey = kf.generatePrivate(privSpec);
        Signature signature = Signature.getInstance("SHA256withRSA");
        signature.initSign(myPrivateKey);
        byte[] data = stringToBeSigned.getBytes("UTF-8");
        signature.update(data);
        byte[] signedBytes = signature.sign();
        signatureString = Base64.encodeBase64String(signedBytes);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return signatureString;
}
}

编辑：

我不明白的部分是此页面上的#3。这表示通过以下方式对该数据的字节数组表示进行签名

实际上很简单，Java 将每个源文件的包导入为 PHP 包含文件。所以第一行是这样做的，然后类的功能几乎与 PHP5 类一样。而已。指定您不理解的内容将有助于更好地解释代码......
