I am trying to execute a multipart request using the below function, but when I create the httpClient I get this exception:
E/AndroidRuntime(8909): Caused by: java.lang.NoSuchFieldError:
org.apache.http.message.BasicLineFormatter.INSTANCE
I am using httpclient-4.3.4 (imports are below as well)
import org.apache.http.HttpEntity;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
public static void uploadFile() throws ClientProtocolException, IOException {
String filepath = Environment.getExternalStorageDirectory() + "/Download/img.jpg";
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpPost uploadFile = new HttpPost("ip/myRestservice");
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addTextBody("field1", "yes", ContentType.TEXT_PLAIN);
File file = new File(filepath);
builder.addBinaryBody("file", file, ContentType.APPLICATION_OCTET_STREAM, "file.ext");
HttpEntity multipart = builder.build();
uploadFile.setEntity(multipart);
CloseableHttpResponse response = httpClient.execute(uploadFile);
HttpEntity responseEntity = response.getEntity();
}
How to solve it?

I'm trying to post a file to a rest API and the code I'm using gives an "Early EOF" error. I've looked around and most of what I'm seeing seems to suggest that the data send doesn't match the expected size of what is being sent.
How do I fix this?
Code is shown below:
(based on How can I make a multipart/form-data POST request using Java?)
import java.io.File;
import java.io.FileInputStream;
import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import lombok.extern.slf4j.Slf4j;
#Slf4j
public class HttpFileUpload {
public static void main(String[] args) throws Exception {
log.info("Starting...");
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpPost uploadFile = new HttpPost("https://url-to-rest-api/api/2.0/dbfs/put");
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addTextBody("path", "/FileStore/my-dir/myfilename.txt", ContentType.TEXT_PLAIN);
String token = "my-security-token";
// This attaches the file to the POST:
File f = new File("C:\\path-to\\my-file.txt");
builder.addBinaryBody(
"file",
new FileInputStream(f),
ContentType.APPLICATION_OCTET_STREAM,
f.getName());
HttpEntity multipart = builder.build();
uploadFile.addHeader("Authorization", "Bearer " + token);
uploadFile.setEntity(multipart);
log.info("Starting upload");
CloseableHttpResponse response = httpClient.execute(uploadFile);
log.info("Done with upload");
HttpEntity responseEntity = response.getEntity();
log.info("Got response");
log.info("Done.");
}
}
This turned out to be a timeout issue. The api I was writing to timed out the request and generated the EOF exception. The api had another call that allowed the file to be uploaded in segments so I modified my solution to use this call instead of trying to upload the entire file in one call.
I am not able to get a response from eclipse when integrated in java code. I am able to retrieve the response from postman/insomnia, but not from eclipse. I masked the token and the URL in this image.
My current code is:
public class Test{
public static void main(String[] args) throws ParseException, IOException {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
httppost.addHeader("Authorization", "Bearer xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
httppost.addHeader("Accept", "*/*");
httppost.addHeader("Content-type", "multipart/form-data; boundary=X-INSOMNIA-BOUNDARY");
httppost.addHeader("Host","process-workorders-mti64mke4a-uc.a.run.app");
File fileToUse = new File("D:\\firstImage.jpg"); // this is the image I am uoploadin
FileBody data = new FileBody(fileToUse);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("mode", new StringBody("api"));
reqEntity.addPart("file", data);
*// seems there is issue here in passing form parameters*
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
System.out.println( response ) ;
HttpEntity resEntity = response.getEntity();
System.out.println( resEntity ) ;
System.out.println( EntityUtils.toString(resEntity) );
EntityUtils.consume(resEntity);
httpclient.getConnectionManager().shutdown();
}
}
Below are the imports:
import java.io.File;
import java.io.IOException;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.ParseException;
import org.apache.http.client.HttpClient;

import org.apache.http.entity.mime.MultipartEntity;

Tried OKHTTPClient and it worked
I would like to create a URI using apache class org.apache.http.client.utils.URIBuilder and I need to not encode query params to percent-encoding.
import org.apache.http.HttpEntity;
import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.client.methods.HttpRequestBase;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import java.net.URI;
public class Main {
public static void main(String[] args) throws Exception {
RequestConfig config = RequestConfig.custom().build();
HttpClientBuilder builder = HttpClientBuilder.create().setDefaultRequestConfig(config);
// URI url = new URI("http://some-website.com/?range=10,20");
// If url is created with the line above the comma "," is not encoded when sending the request
// When you use URIBuilder the comma "," is converted to "%2C"
URIBuilder uribuilder = new URIBuilder("http://some-website.com/");
uribuilder.addParameter("range", "10,20");
URI url = uribuilder.build();
System.out.println("URL => " + url.toString());
HttpHost targetHost = new HttpHost(url.getHost(), url.getPort(), url.getScheme());
HttpClient client = builder.build();
HttpRequestBase req = new HttpPost(url);
HttpResponse httpResponse = client.execute(targetHost, req);
HttpEntity entity = httpResponse.getEntity();
String responseString = EntityUtils.toString(entity, "UTF-8");
System.out.println(responseString);
System.out.println("Finished");
}
}
Is there a way to do that using the URIBuilder class like some flag I don't know?
I would appreciate other suggests (maybe better ways than my code) to accomplish this. But I can't send the characters in query string encoded.
Thanks in advance.
I have been able to successfully authentication to a service that requires ntlm authentication when using the WinHttpClients and a GET request. However when I try to do a POST I always get a 401 return code. Has anyone done this sucessfully before?

public class WindowsAuthPOst {
public static void main (String []args) throws Exception, IOException
{
org.apache.log4j.BasicConfigurator.configure();
CloseableHttpClient httpclient = WinHttpClients.createDefault();
HttpHost target = new HttpHost("SomeHost.domain", 443, "https");
HttpClientContext context = HttpClientContext.create();
HttpGet httpget = new HttpGet("/some/Service.svc");
CloseableHttpResponse response1 = httpclient.execute(target, httpget, context);
try {
HttpEntity entity1 = response1.getEntity();
} finally {
response1.close();
}
// Execute an expensive method next reusing the same context (and connection)
HttpPost httppost = new HttpPost("/some/Service.svc");
httppost.setHeader("SOAPAction", "Some Soap Action");
httppost.setEntity(new StringEntity("Soap Payload"));
CloseableHttpResponse response2 = httpclient.execute(target, httppost, context);
try {
HttpEntity entity2 = response2.getEntity();
} finally {
response2.close();
}
}
}
You can check if it is available with.
if (!WinHttpClients.isWinAuthAvailable()) {
System.out.println("Integrated Win auth is not supported!!!");
}
If not, it could be that you do not have jna.jar in your classpath. It depends on jna and will silently return false on the above if it not there, see source code.
Try with get (or options) before post. Some webservers requires that because of CORS.

This is the code that worked for me to consume a webservice say for example "urn:authe#createEmp". Now in the same server when i consume
"urn:authe#createUser" it throws java.util.zip.ZipException . Following is the program.
package pack;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;

import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.HttpClientBuilder;
public class WebServiceClient {
public static void main(String[] args) throws ClientProtocolException, IOException {
String url = "http://localhost/ProjectName/WebService.php";
HttpClient client = HttpClientBuilder.create().build();
HttpPost post = new HttpPost(url);
post.setHeader("SOAPAction", "urn:authe#createUser");
MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.addTextBody("firstname", "Siva", ContentType.TEXT_PLAIN);
builder.addTextBody("lastname", "LASTNAME", ContentType.TEXT_PLAIN);
// builder.addBinaryBody("file", new
// File("..."),ContentType.APPLICATION_OCTET_STREAM, "file.ext");
HttpEntity multipart = builder.build();
post.setEntity(multipart);
HttpResponse response = client.execute(post);
System.out.println("Response Code : " + response.getStatusLine().getStatusCode());
BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
StringBuffer result = new StringBuffer();
String line = "";
while ((line = rd.readLine()) != null) {
result.append(line);
}
System.out.println(result.toString());
}
}
Response from console is:
