http请求携带文件
在进行HttpPost请求时,如果需要带文件,可以使用MultipartEntityBuilder来构建上传文件的表单。首先,创建一个CloseableHttpClient对象,然后指定请求的URL。接下来,创建一个HttpPost对象,并将URL设置为HttpPost的参数。然后,创建一个MultipartEntityBuilder对象,并使用addTextBody方法添加普通参数,使用addPart方法添加上传的文件。最后,使用build方法构建HttpEntity对象,并将其设置为HttpPost的实体。最后,执行HttpPost请求并获取响应。以下是一个示例代码:
```java
CloseableHttpClient httpClient = HttpClients.createDefault();
String url = "https://frt.aaa.bbb:8080/test/oneServlet";
HttpPost httpPost = new HttpPost(url);
File file = new File("filePath");
MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create();
entityBuilder.addTextBody("test", "test");
entityBuilder.addPart("fileName", new FileBody(file));
HttpEntity httpEntity = entityBuilder.build();
httpPost.setEntity(httpEntity);
CloseableHttpResponse response = httpClient.execute(httpPost);
```
请注意,上述代码中的"filePath"应替换为实际的文件路径。这样,就可以使用HttpPost请求带文件了。
