android 的android httpClient詳解

Android HttpClient是Android平臺提供的一個HTTP請求客戶端，使用它可以方便地發(fā)送HTTP請求并獲得請求的響應。下面是Android HttpClient的詳細解釋：

1. 創(chuàng)建HttpClient對象：

HttpClient httpClient = new DefaultHttpClient();

2. 創(chuàng)建請求方法：

HttpGet httpGet = new HttpGet(url);  // 創(chuàng)建GET請求
HttpPost httpPost = new HttpPost(url);  // 創(chuàng)建POST請求

3. 設置請求參數(shù)：

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("param1", "value1"));
httpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));

4. 發(fā)送請求并獲取響應：

HttpResponse httpResponse = httpClient.execute(httpGet);  // 發(fā)送GET請求
HttpResponse httpResponse = httpClient.execute(httpPost);  // 發(fā)送POST請求

5. 處理響應：

int statusCode = httpResponse.getStatusLine().getStatusCode();  // 獲取響應狀態(tài)碼
if (statusCode == HttpStatus.SC_OK) {
HttpEntity httpEntity = httpResponse.getEntity();  // 獲取響應實體
String response = EntityUtils.toString(httpEntity);  // 將實體轉換為字符串
// 處理響應數(shù)據
} else {
// 處理錯誤情況
}

注意：Android HttpClient已被標記為過時，推薦使用HttpURLConnection或OkHttp來替代。
