Base64加密方式认证方式下的basic auth。

注意 base64的basic auth 使用

httpclient自带的认证方式如下会认证失败:CredentialsProvider provider = new BasicCredentialsProvider();UsernamePasswordCredentials credentials

= new UsernamePasswordCredentials("username", "user1Pass");provider.setCredentials(AuthScope.ANY, credentials);HttpClient client = HttpClientBuilder.create() .setDefaultCredentialsProvider(provider) .build();

成功通过的例子:package com.biologic.api.service.impl;import java.io.IOException;import java.util.Base64;import java.util.Map;import org.apache.http.HttpEntity;import org.apache.http.HttpResponse;import org.apache.http.client.ClientProtocolException;import org.apache.http.client.methods.HttpPost;import org.apache.http.entity.ContentType;import org.apache.http.entity.mime.MultipartEntityBuilder;import org.apache.http.entity.mime.content.StringBody;import org.apache.http.impl.client.CloseableHttpClient;import org.apache.http.impl.client.HttpClientBuilder;import org.apache.http.util.EntityUtils;import org.springframework.stereotype.Service;import com.biologic.api.service.HttpService;@Service

public class HttpServiceImpl implements HttpService {

@Override

public int httpClientWithBasicAuth(String username, String password, String uri, Map paramMap) {

try {

// 创建HttpClientBuilder

HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();

CloseableHttpClient closeableHttpClient = httpClientBuilder.build();

HttpPost httpPost = new HttpPost(uri);

//添加http头信息

httpPost.addHeader("Authorization", "Basic " + Base64.getUrlEncoder().encodeToString((username + ":" + password).getBytes()));

MultipartEntityBuilder builder = MultipartEntityBuilder.create();

paramMap.forEach((k,v)->{

builder.addPart(k, new StringBody(v, ContentType.MULTIPART_FORM_DATA));

});

HttpEntity postEntity = builder.build();

httpPost.setEntity(postEntity);

String result = "";

HttpResponse httpResponse = null;

HttpEntity entity = null;

try {

httpResponse = closeableHttpClient.execute(httpPost);

entity = httpResponse.getEntity();

if( entity != null ){

result = EntityUtils.toString(entity);

}

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

// 关闭连接

closeableHttpClient.close();

System.out.println(result);

}catch (Exception e) {

System.out.println(e.getStackTrace());

}

return 0;

}

}
