Question

我正在尝试使用HttpClient DELETE方法从列表中删除项目。我想使用请求体发送相关的item_id。我使用以下方式发送数据。

 DefaultHttpClient httpclient = new DefaultHttpClient();
                httpclient = HttpUtils.getNewHttpClient();
                HttpDelete httpPostRequest = new HttpDelete(URL);     

                **httpPostRequest.setHeader("item_id",id);**
                httpPostRequest.addHeader("Authorization", getB64Auth(username,password));
                httpPostRequest.setHeader("Accept", "application/json");
                httpPostRequest.setHeader("Content-type", "application/json");
                httpPostRequest.setHeader("Accept-Encoding", "gzip");

但是我无法将项目删除到服务器数据库中。如何在HttpDelete中使用Request body？

Answer 1

根据HTTP / 1.1规范，您不能发送除POST和PUT之外的任何实体。

使用请求参数或标头属性。您可以使用URI Builder：

URI myURI = android.net.Uri.Builder.path(myPathString).query("item_id=1").build();

基于here的答案，该答案应该为您提供带有实体字段的DELETE请求。一旦你创建了自己的请求类型，就可以了;

List<NameValuePair> deleteParams = new ArrayList<>();
deleteParams.add(new BasicNameValuePair("item_id", id));
UrlEncodedFormEntity entity = new UrlEncodedFormEntity(deleteParams);

HttpDeleteWithBody deleteRequest = new HttpDeleteWithBody(URL);
deleteRequest.addHeader("Authorization", getB64Auth(username,password));
deleteRequest.setHeader("Accept", "application/json");
deleteRequest.setHeader("Content-type", "application/json");
deleteRequest.setHeader("Accept-Encoding", "gzip"); 
deleteRequest.setEntity(entity);
