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？？？excuseme?
packagecom.vol.timingTasks;
importorg.apache.http.HttpEntity;
importorg.apache.http.HttpResponse;
importorg.apache.http.auth.AuthScope;
importorg.apache.http.auth.UsernamePasswordCredentials;
importorg.apache.http.client.CredentialsProvider;
importorg.apache.http.client.HttpClient;
importorg.apache.http.client.methods.HttpGet;
importorg.apache.http.impl.client.BasicCredentialsProvider;
importorg.apache.http.impl.client.CloseableHttpClient;
importorg.apache.http.impl.client.DefaultHttpClient;
importorg.apache.http.impl.client.HttpClientBuilder;
importorg.apache.http.util.EntityUtils;
importjava.io.IOException;

publicstaticvoidmain(String[]args)throwsException{

}
/*

publicstaticvoidgetDataA()throwsException{

HttpClienthttpClient=newDefaultHttpClient();
StringprojectName="中科洛阳信息产业园项目(一期)";
Stringurl="http://labour.ztjs.cn/clound/wsForThird/laboursByProjectName/"+projectName;
HttpGetget=newHttpGet(url);
try{

//Createtheauthenticationscope

}catch(IOExceptione){
}
}
}
把访问地址：http://labour.ztjs.cn/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：
packagecom.vol.timingTasks;
importorg.apache.http.HttpEntity;
importorg.apache.http.HttpResponse;
importorg.apache.http.auth.AuthScope;
importorg.apache.http.auth.UsernamePasswordCredentials;
importorg.apache.http.client.CredentialsProvider;
importorg.apache.http.client.HttpClient;
importorg.apache.http.client.methods.HttpGet;
importorg.apache.http.impl.client.BasicCredentialsProvider;
importorg.apache.http.impl.client.CloseableHttpClient;
importorg.apache.http.impl.client.DefaultHttpClient;
importorg.apache.http.impl.client.HttpClientBuilder;
importorg.apache.http.util.EntityUtils;
importjava.io.IOException;
/**

publicclassXBXmain{
privatefinalstaticStringENCODE="utf-8";
publicstaticvoidmain(String[]args)throwsException{
getDataA();
}
/*
*Basic验证
*用户名：
*密钥：
*/
publicstaticvoidgetDataA()throwsException{
HttpResponsehttpResponse=null;
HttpClienthttpClient=newDefaultHttpClient();
StringprojectName="中科洛阳信息产业园项目(一期)";
Stringurl="http://labour.ztjs.cn/clound/wsForThird/laboursByProjectName/"+java.net.URLEncoder.encode(projectName,ENCODE);//URL中文转码
HttpGetget=newHttpGet(url);
try{
//创建HttpClientBuilder
HttpClientBuilderhttpClientBuilder=HttpClientBuilder.create();
//设置BasicAuth
CredentialsProviderprovider=newBasicCredentialsProvider();
//Createtheauthenticationscope
AuthScopescope=newAuthScope(AuthScope.ANY_HOST,AuthScope.ANY_PORT,AuthScope.ANY_REALM);
//Createcredentialpair，在此处填写用户名和密码
UsernamePasswordCredentialscredentials=newUsernamePasswordCredentials("","");
//Injectthecredentials
provider.setCredentials(scope,credentials);
//Setthedefaultcredentialsprovider
httpClientBuilder.setDefaultCredentialsProvider(provider);
//HttpClient
CloseableHttpClientcloseableHttpClient=httpClientBuilder.build();
httpResponse=closeableHttpClient.execute(get);
HttpEntityhttpEntity=httpResponse.getEntity();
StringhttpResult=EntityUtils.toString(httpEntity);
StringhttpResult2=EntityUtils.toString(httpEntity);
}catch(IOExceptione){
}
}
}
再试试，请求成功，只需要转下编码：
Stringurl="http://labour.ztjs.cn/clound/wsForThird/laboursByProjectName/"+java.net.URLEncoder.encode(projectName,ENCODE);//URL 中文转码
