英文:
Why http request made with Apache HttpClient5 receives http 404 error if preemptive BASIC authentication used
问题
您想要翻译的内容如下：
我需要关于描述在此处 的apache http 5客户端示例的帮助。我的目标是与CURL完全相同：
curl --verbose --user "admin:admin" --data-binary @20200802112010-test.csv 'http://localhost:8080/api/test/write?db=test' --trace-ascii trace.txt
我修改了示例以执行POST而不是GET：
private void _sendFile(File file) throws IOException, URISyntaxException {
BasicScheme basicScheme = new BasicScheme();
basicScheme.initPreemptive(new UsernamePasswordCredentials("admin", "admin".toCharArray()));
HttpClientContext httpClientContext = HttpClientContext.create();
HttpHost httpHost = new HttpHost("http", "localhost", 8080);
httpClientContext.resetAuthExchange(httpHost, basicScheme);
try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
FileEntity fileEntity = new FileEntity(file, ContentType.APPLICATION_FORM_URLENCODED);
HttpPost httpPost = new HttpPost("http://localhost:8080/api/test/write?db=test");
httpPost.setEntity(fileEntity);
try (final CloseableHttpResponse httpResponse = httpClient.execute(httpHost, httpPost, httpClientContext)) {
if (httpResponse.getCode() == 204) {
return;
}
_logger.warn("Unexpected return code {}", httpResponse.getCode());
}
}
}
我的服务器端代码是由JHipster生成的Spring Boot应用程序，处理请求的控制器如下：
@Profile({"dev", "igor"})
@RequestMapping("/api/test")
@RestController
public class DBEndpointSimulatorResource {
/**
* {@code POST /write} : Simulates file import on INRAE InfluxDB server.
*
* @param dataBase the database name
* @param content the request body
*
* @return the {@link ResponseEntity} with status {@code 204 (No Content)}
* @throws URISyntaxException if the Location URI syntax is incorrect.
*/
@PostMapping("/write")
public ResponseEntity<?> simulateWrite(@RequestParam("db") String dataBase, @RequestBody String content)
throws URISyntaxException {
_logger.debug("REST request to process file for: {}", dataBase);
if (content == null) {
throw new BadRequestAlertException(
"A content must not be empty", "DB FILE", "ERROR-SIMULATOR-001");
}
final ResponseEntity.HeadersBuilder<?> headersBuilder = ResponseEntity.noContent();
return headersBuilder.build();
}
private final Logger _logger = LoggerFactory.getLogger(DBEndpointSimulatorResource.class);
}
执行_sendFile代码后收到HTTP错误404。我为httpclient 5打开了日志记录，它记录了与服务器端的正常连接，服务器端以404响应：
...（中间部分省略）
起初，我认为Spring Boot端的控制器有问题，但我尝试了与cURL相同的请求，最终成功：
...（中间部分省略）
我看到了内容类型方面的差异，其中Apache HttpClient添加了字符编码。现在我想知道：
1. 我是否应该强制使用UTF-8字符编码，如何实现？还是
2. 我的Apache HttpClient POST示例中是否有其他问题？
请告诉我您需要对其中哪些部分进行翻译。
英文:
I need help with apache http 5 client example described here. My goal is to do exactly the same as CURL:
curl --verbose --user "admin:admin" --data-binary @20200802112010-test.csv 'http://localhost:8080/api/test/write?db=test' --trace-ascii trace.txt
I modified example to perform POST instead of GET:
private void _sendFile(File file) throws IOException, URISyntaxException {
BasicScheme basicScheme = new BasicScheme();
basicScheme.initPreemptive(new UsernamePasswordCredentials("admin", "admin".toCharArray()));
HttpClientContext httpClientContext = HttpClientContext.create();
HttpHost httpHost = new HttpHost("http", "localhost", 8080);
httpClientContext.resetAuthExchange(httpHost, basicScheme);
try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
FileEntity fileEntity = new FileEntity(file, ContentType.APPLICATION_FORM_URLENCODED);
HttpPost httpPost = new HttpPost("http://localhost:8080/api/test/write?db=test");
httpPost.setEntity(fileEntity);
try (final CloseableHttpResponse httpResponse = httpClient.execute(httpHost, httpPost, httpClientContext)) {
if (httpResponse.getCode() == 204) {
return;
}
_logger.warn("Unexpected return code {}", httpResponse.getCode());
}
}
}
My server side code is Spring Boot App generated by JHipster and controller that handles request is this:
@Profile({"dev", "igor"})
@RequestMapping("/api/test")
@RestController
public class DBEndpointSimulatorResource {
/**
* {@code POST /write} : Simulates file import on INRAE InfluxDB server.
*
* @param dataBase the database name
* @param content the request body
*
* @return the {@link ResponseEntity} with status {@code 204 (No Content)}
* @throws URISyntaxException if the Location URI syntax is incorrect.
*/
@PostMapping("/write")
public ResponseEntity<?> simulateWrite(@RequestParam("db") String dataBase, @RequestBody String content)
throws URISyntaxException {
_logger.debug("REST request to process file for: {}", dataBase);
if (content == null) {
throw new BadRequestAlertException(
"A content must not be empty", "DB FILE", "ERROR-SIMULATOR-001");
}
final ResponseEntity.HeadersBuilder<?> headersBuilder = ResponseEntity.noContent();
return headersBuilder.build();
}
private final Logger _logger = LoggerFactory.getLogger(DBEndpointSimulatorResource.class);
}
Once executed _sendFile code receives HTTP error 404. I turned on logging for httpclient 5 and it logs out proper connect to server side which responds with 404:

In the beginning I thought controller at spring boot side is wrong, but I tried same request with cURL it ended with success:
=> Send header, 236 bytes (0xec)

I see difference in content type where apache http client appends character encoding. Now I wonder:
- should I force utf8 character encoding and how?? or
- something else is wrong in my apache httpclient post example

以下是翻译好的部分：
问题描述从未在生产环境中发生，只在我的本地开发环境中出现，该环境是MacOSX Catalina。
我很少重新启动我的MacBookPro，似乎是这导致了问题。在重新启动硬件后，问题再也没有发生。
这并不完全是答案，但这是唯一使问题停止的方法：(

Problem I described never occurred in production, only in my local development environment which is MacOSX Catalina.
I rarely restart my MacBookPro and seems it caused issue. After restarting hardware, issue never happen again.
