Setting the entity object to the RequestBuilder Set the above created multipart entity to the RequestBuilder using the setEntity() method of the RequestBuilder class. Step 8 - Set the entity object to the RequestBuilder RequestBuilder reqbuilder = RequestBuilder.post("") To which you wanted to send the request it as a parameter. If the request is of type PUT or POST, it adds the parameters to the request as URL encoded entity.Ĭreate a RequestBuilder object (of type POST) using the post() method. The class RequestBuilder is used to build request by adding parameters to it. HttpEntity mutiPartHttpEntity = entityBuilder.build() Building a single entity using the parts Using this method, build all the parts into a single HttpEntity. You can build all these parts to a single entity using the build() method of the MultipartEntityBuilder class. Add the desired contents using these methods.Įntitybuilder.addTextBody("sample_text", "This is the text part of our file") Įntitybuilder.addBinaryBody("image", new File("logo.png")) Using the methods addTextBody(), addPart() and, addBinaryBody(), you can add simple text, files, streams, and other objects to a MultipartBuilder. Set it to the desired mode using the setMode() method.ĮtMode(HttpMultipartMode.BROWSER_COMPATIBLE) MultipartEntityBuilder entitybuilder = MultipartEntityBuilder.create() Ī MultipartEntityBuilder has three modes: STRICT, RFC6532, and BROWSER_COMPATIBLE. Create its object using the create() method (of the same class). The MultipartEntityBuilder class is used to build the multi-part HttpEntity object. Instantiate this class by passing a File object and a ContentType object representing the type of the content.įileBody filebody = new FileBody(file, ContentType.DEFAULT_BINARY) Using this method, create an HttpClient object −ĬloseableHttpClient httpclient = HttpClients.createDefault() įileBody class represents the binary body part backed by a file. The createDefault() method of the HttpClients class returns an object of the class CloseableHttpClient, which is the base implementation of the HttpClient interface. In general, any multipart upload contains three parts.įor the multipart upload using HttpClient, we need to follow the below steps −Ĭomplete the build and obtain a multipart HttpEntity.īuild request by setting the above muti-part entity.įollowing are the steps to upload a multipart entity using the HttpClient library. In this chapter, we demonstrate the multipart upload in HTTP client by uploading a simple text file. Using HttpClient, we can perform Multipart upload, i.e., we can upload larger objects in
