使用httpClient 模拟post请求上传图片:
public class HttpFileUpload {
//url:请求路经
//filePath:需要上传的文件路径
public static JSONObject fileUpload(String url,String filePath){
CloseableHttpClient httpclient = HttpClients.createDefault();
//CloseableHttpClient httpclient = HttpClientBuilder.create().build();
try {
HttpPost httppost = new HttpPost(url);
RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(200000).setSocketTimeout(200000).build();
httppost.setConfig(requestConfig);
FileBody bin = new FileBody(new File(filePath));
StringBody comment = new StringBody("This is comment", ContentType.TEXT_PLAIN);
HttpEntity reqEntity = MultipartEntityBuilder.create().addPart("file", bin).addPart("comment", comment).build();
httppost.setEntity(reqEntity);
System.out.println("executing request " + httppost.getRequestLine());
CloseableHttpResponse response = httpclient.execute(httppost);
try {
System.out.println(response.getStatusLine());
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
String responseEntityStr = EntityUtils.toString(response.getEntity());
System.out.println(responseEntityStr);
System.out.println("Response content length: " + resEntity.getContentLength());
}
EntityUtils.consume(resEntity);
} finally {
response.close();
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
httpclient.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
