Example 1 with HeaderGroup

use of org.apache.http.message.HeaderGroup in project azure-tools-for-java by Microsoft.

the class SharedKeyHttpObservable method request.

@Override
public Observable<CloseableHttpResponse> request(final HttpRequestBase httpRequest, @Nullable final HttpEntity entity, final List<NameValuePair> parameters, final List<Header> addOrReplaceHeaders) {
    // We add necessary information to a temporary header group which is used to generate shared keys
    final HeaderGroup headerGroup = new HeaderGroup();
    headerGroup.setHeaders(getDefaultHeaderGroup().getAllHeaders());
    if (entity != null) {
        // We need to set content-length to generate shared key. What need to be point out is that the
        // HttpObservable auto adds this header and calculates length when executing, so the content-length header
        // cannot be added to default header group in case of duplication.
        headerGroup.addHeader(new BasicHeader("Content-Length", String.valueOf(entity.getContentLength())));
    }
    ofNullable(addOrReplaceHeaders).orElse(emptyList()).forEach(headerGroup::addHeader);
    String key = cred.generateSharedKey(httpRequest, headerGroup, ofNullable(parameters).orElse(emptyList()));
    getDefaultHeaderGroup().updateHeader(new BasicHeader("Authorization", key));
    return super.request(httpRequest, entity, ofNullable(parameters).orElse(emptyList()), ofNullable(addOrReplaceHeaders).orElse(emptyList()));
