Question

目前我使用HttpClient从android连接到.net WEB API，我已经能够进行GET和POST来读/写数据。但是，我想进行更新和删除。

我尝试使用POST执行此操作，但只需创建更多记录。这是我的POST代码，如何将其更改为PUT或DELETE？

        HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://mywebsite.net/api/employees/6");

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(5);
        nameValuePairs.add(new BasicNameValuePair("firstName", "UpdatedHello"));
        nameValuePairs.add(new BasicNameValuePair("lastName", "World"));
        nameValuePairs.add(new BasicNameValuePair("employee_name", "UpdatedHello World"));
        nameValuePairs.add(new BasicNameValuePair("password", "xxx"));
        nameValuePairs.add(new BasicNameValuePair("isActive", "1"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));


        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

您有PutMethod和DeleteMethod API用于执行PUT和DELETE Http请求。示例用法如下所述

PUT请求 - put方法非常简单，它需要放置一个URL，并要求将请求方法的主体设置为要上载的数据。可以使用输入流或字符串设置正文。此方法通常在公共服务器上禁用，因为通常不允许客户端将新文件放在服务器上或替换现有文件。

        PutMethod put = new PutMethod("http://jakarta.apache.org");
        put.setRequestBody(new FileInputStream("UploadMe.gif"));
        // execute the method and handle any error responses.
        ...
        // Handle the response.  Note that a successful response may not be
        // 200, but may also be 201 Created, 204 No Content or any of the other
        // 2xx range responses.

删除请求 - 删除方法用于提供URL以删除资源并从服务器读取响应。此方法通常也在公共服务器上禁用，因为它通常是不可取的允许客户端删除服务器上的文件。

        DeleteMethod delete = new DeleteMethod("http://jakarata.apache.org");
        // execute the method and handle any error responses.
        ...
        // Ensure that if there is a response body it is read, then release the
        // connection.
        ...
        delete.releaseConnection();

我可以使用HttpClient进行PUT或删除
