Question

我正在构建一个java应用程序，以便使用amazon cloudsearch索引一些json文件。我认为我已经使用了正确的aws文档，但我无法使我的应用程序正常工作。

package com.myPackage;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.cloudsearchdomain.AmazonCloudSearchDomainClient;
import com.amazonaws.services.cloudsearchdomain.model.UploadDocumentsRequest;
import com.amazonaws.services.cloudsearchdomain.model.UploadDocumentsResult;

public class App 
{
    public static final String ACCESS_KEY = "myAccessKey";
    public static final String SECRET_KEY = "mySecretKey";
    public static final String ENDPOINT = "myDocumentEndpoint";

    public static void main( String[] args ) throws FileNotFoundException
    {
        AWSCredentials credentials = new BasicAWSCredentials(ACCESS_KEY, SECRET_KEY);
        AmazonCloudSearchDomainClient domain = new AmazonCloudSearchDomainClient(credentials);
        domain.setEndpoint(ENDPOINT);

        File file = new File("path to my file");
        InputStream docAsStream = new FileInputStream(file);
        UploadDocumentsRequest req = new UploadDocumentsRequest();
        req.setDocuments(docAsStream);
        System.out.print(file.length());
        UploadDocumentsResult result = domain.uploadDocuments(req);//here i get the exception

        System.out.println(result.toString());
//      
//      SearchRequest searchReq = new SearchRequest().withQuery("my Search request");
//      SearchResult s_res = domain.search(searchReq);
//      System.out.println(s_res);
    }
}

问题是我收到以下错误：

这是json文件：

{"a":123,"b":"4 5 6"}

Answer 1

您从CloudSearch收到403 Forbidden错误，这意味着您无权将文档上传到该域。

您是否确实使用“myAccessKey”作为访问密钥值，或者在发布此密码时是否对其进行了编辑？如果您从未设置过，那么您需要设置访问密钥;否则，请通过AWS Web控制台检查CloudSearch域上的访问策略，因为它可能配置为根据IP地址或其他一些条件接受/拒绝提交。

Answer 2

首先：请不要将您的凭据放在您的代码中。很容易意外地将凭证检查到版本控制中，或以其他方式发布它们。如果您的凭据位于默认位置，则可以执行以下操作：

AmazonCloudSearchDomainClient客户端=新的AmazonCloudSearchDomainClient（）;

SDK会找到它们。

403s的一个常见原因是端点错误。确保端点字符串末尾没有/ documents / batch。 SDK会添加它。

另一件要尝试的是设置内容长度：

    req.setContentLength(file.length());

我的代码有，并且有效，并且与您的代码相同。
