> --------------------------------------------

> Key: HTTPCLIENT-2166
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2166
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 5.1
> Reporter: smallufo
> Priority: Major
> Attachments: appengine.png
>
>
> I build a proxy server on GAE which receives 'url' parameter , and retrieve
> content .
> It works well when client uses httpClient 4.5 , but after httpClient
> upgrading to 5.1 , I found it has problems encoding character.
> Full test code :
>
> {code:java}
> import mu.KotlinLogging
> import org.apache.http.client.methods.HttpGet
> import org.apache.http.impl.client.HttpClientBuilder
> import kotlin.test.Test
> class ApacheHttpClientTest {
> private val logger = KotlinLogging.logger { }
> val url =
> "https://myProject.appspot.com/proxy?url=https://google.com/search?q=é";
> @Test
> fun testV4() {
> val httpClient = HttpClientBuilder.create().build()
> val httpGet = HttpGet(url)
> logger.info { "httpGet = $httpGet" }
> logger.info {
> "statusCode = ${httpClient.execute(httpGet).statusLine.statusCode}"
> }
> }
> @Test
> fun testV5() {
> val httpClient =
> org.apache.hc.client5.http.impl.classic.HttpClientBuilder.create().build()
> val httpGet = org.apache.hc.client5.http.classic.methods.HttpGet(url)
> logger.info { "httpGet = $httpGet" }
> logger.info {
> "code = ${httpClient.execute(httpGet).code}"
> }
> }
> }
> {code}
>
>
> When `testV4` runs , it correctly encode é to %C3%A9 in the URL. And GAE
> console shows correct query string :
> {code:java}
> myapp.ProxyServlet doGet: url = https://google.com/search?q=é{code}
>
> But when testV5 runs , it incorrectly encode é to %E9 . In GAE console it
> shows :
>
> {code:java}
> myapp.ProxyServlet doGet: url = https://google.com/search?q=�
> {code}
>
> The screen shot is below :
> !appengine.png!
