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;impor

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:
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.cn/clound/wsForThird/laboursByProjectName/"+java.net.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.cn/clound/wsForThird/laboursByProjectName/"+java.net.URLEncoder.encode(projectName, ENCODE);//URL 中文 转码
