Question

I am suppose to send song (mp3/wav) file and some data through secure restful web service. I am using MultipartEntity to make HttpPost request. but When I execute it through HttpClient, the server replies this error

HTTP Status 400 – Bad Request
type: Status report
message : Bad Request
The request sent by the client was syntactically incorrect (Bad Request).

But the service is doing very well if we call it from its Web interface. please help

its the code

HttpClient httpclient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost();
        try {
            MultipartEntity reqEntity = new MultipartEntity();

            reqEntity.addPart("email", new StringBody("[e-mail]"));
            reqEntity.addPart("password", new StringBody("123"));
            reqEntity.addPart("title", new StringBody("My new song"));
            reqEntity.addPart("musicData", new FileBody(new File(FilePath))); 

            // FIlePath is path to file and contains correct file location

            postRequest.setEntity(reqEntity);

            postRequest.setURI(new URI(ServiceURL));
            HttpResponse response = httpclient.execute(postRequest);

        } catch (URISyntaxException e) {
            Log.e("URISyntaxException", e.toString());
        } 

I also included apache-mime4j, httpclient, httpcore and httpmime jars for MultipartEntity.

This is HTML page snap for the Service.

Try removing the setURI method and passing the URL in when you create your HttpPost object, as follows. This worked for me (more here).

HttpClient httpclient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(ServiceURL);
try {
    MultipartEntity reqEntity = new MultipartEntity();

    reqEntity.addPart("email", new StringBody("[e-mail]"));
    reqEntity.addPart("password", new StringBody("123"));
    reqEntity.addPart("title", new StringBody("My new song"));
    reqEntity.addPart("musicData", new FileBody(new File(FilePath)));     
    postRequest.setEntity(reqEntity);

    HttpResponse response = httpclient.execute(postRequest);

} catch (URISyntaxException e) {
    Log.e("URISyntaxException", e.toString());
}
