HttpClient 请求 URL字符集转码问题

HttpClient 请求 URL字符集转码问题

问题是这样的，我用eclipse发送httpclient请求如下没有问题，但是在idea中就返回400，为毛呢？？？excuse me?

package com.vol.timingTasks;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.auth.AuthScope;

import org.apache.http.auth.UsernamePasswordCredentials;

import org.apache.http.client.CredentialsProvider;

import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.impl.client.BasicCredentialsProvider;

import org.apache.http.impl.client.CloseableHttpClient;

import org.apache.http.impl.client.DefaultHttpClient;

import org.apache.http.impl.client.HttpClientBuilder;

import org.apache.http.util.EntityUtils;

import java.io.IOException;

/**

* 数据抽取测试类

*

* @author xbx

*

*/

public class XBXmain {

private final static StrinSfzRRCTHJg ENCODE = "utf-8";

public static void main(String[] args) throws Exception {

getDahttp://taA();

}

/*

* Basic验证

* 用户名：

* 密钥：

*/

public static void getDataA() throws Exception{

HttpResponse httpResponse = null;

HttpClient httpClient = new DefaultHttpClient();

String projectName = "中科洛阳信息产业园项目(一期)";

String url = "http://labour.ztjs-/clound/wsForThird/laboursByProjectName/"+projectName ;

HttpGet get = new HttpGet(url);

try {

// 创建HttpClientBuilder

HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();

// 设置BasicAuth

CredentialsProvider provider = new BasicCredentialsProvider();

// Create the authentication scope

AuthScope scope = new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM);

// Create credential pair，在此处填写用户名和密码

UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("", "");

// Inject the credentials

provider.setCredentials(scope, credentials);

// Set the default credentials provider

httpClientBuilder.setDefaultCredentialsProvider(provider);

// HttpClient

CloseableHttpClient closeableHttpClient = httpClientBuilder.build();

httpResponse = closeableHttpClient.execute(get);

HttpEntity httpEntity = httpResponse.getEntity();

String httpResult = EntityUtils.toString(httpEntity);

String httpResult2 = EntityUtils.toString(httpEntity);

} catch (IOException e) {

}

}

}

把 访问地址：http://labour.ztjs-/clound/wsForThird/laboursByProjectName/中科洛阳信息产业园项目(一期) 放在谷歌浏览器，然后再复制出来，发现汉字编码格式变了。ok，那就先转换下编码格式再发送请求。  修改后代码如下：

package com.vol.timingTasks;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.auth.AuthScope;

import org.apache.http.auth.UsernamePasswordCredentials;

import org.apache.http.client.CredentialsProvider;

import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.impl.client.BasicCredentialsProvider;

import org.apache.http.impl.client.CloseableHttpClient;

import org.apache.http.impl.client.DefaultHttpClient;

import org.apache.http.impl.client.HttpClientBuilder;

import org.apache.http.util.EntityUtils;

import java.io.IOException;

/**

* 数据抽取测试类

*

* @author xbx

*

*/

public class XBXmain {

private final static String ENCODE = "utf-8";

public static void main(String[] args) throws Exception {

getDataA();

}

/*

* Basic验证

* 用户名：

* 密钥：

*/

public static void getDataA() throws Exception{

HttpResponse httpResponse = null;

HttpClient httpClient = new DefaultHttpClient();

String projectName = "中科洛阳信息产业园项目(一期)";

String url = "http://labour.ztjs-/clound/wsForThird/laboursByProjectName/"+java-.URLEncoder.encode(projectName, ENCODE);//URL 中文 转码

HttpGet get = new HttpGet(url);

try {

// 创建HttpClientBuilder

HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();

// 设置BasicAuth

CredentialsProvider provider = new BasicCredentialsProvider();

// Create the authentication scope

AuthScope scope = new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM);

// Create credential pair，在此处填写用户名和密码

UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("", "");

// Inject the credentials

provider.setCredentials(scope, credentials);

// Set the default credentials provider

httpClientBuilder.setDefaultCredentialsProvider(provider);

// HttpClient

CloseableHttpClient closeableHttpClient = httpClientBuilder.build();

httpResponse = closeableHttpClient.execute(get);

HttpEntity httpEntity = httpResponse.getEntity();

String httpResult = EntityUtils.toString(httpEntity);

String httpResult2 = EntityUtils.toString(httpEntity);

} catch (IOException e) {

}

}

}

再试试，请求成功，只需要转下编码：

String url = "http://labour.ztjs-/clound/wsForThird/laboursByProjectName/"+java-.URLEncoder.encode(projectName, ENCODE);//URL  中文 转码
