java的httpclient和okhttp請求網絡，都比py的requests麻煩多，也比py的自帶包urllib麻煩些。現在想想requests真是for humans的，拿來即用，基本無特殊情況無需二次封裝。
java的還是要先封裝成get post工具類比較好用，工具類即是靜態方法的類，比較通用，無需new一個對象。和py的@staticmethod方法一樣。
package com.touna.httprequest; import java.util.HashMap; import java.util.Set; import okhttp3.FormBody;import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.RequestBody; import okhttp3.Response; public class HttpUtil { public static void post(String url, HashMap<String, String > paramsMap){ //這裏沒有返回，也可以返回string OkHttpClient mOkHttpClient = new OkHttpClient(); FormBody.Builder formBodyBuilder= new FormBody.Builder(); Set<String> keySet = paramsMap.keySet(); for(String key:keySet) { String value = paramsMap.get(key); formBodyBuilder.add(key,value); } FormBody formBody = formBodyBuilder.build(); Request request= new Request .Builder() .post(formBody) .url(url) .build(); try (Response response = mOkHttpClient.newCall(request).execute()) { System.out.println(response.body().string()); }catch (Exception e){ e.printStackTrace(); } } public static void main(String[] args) { HashMap<String,String> paramsMap = new HashMap<String, String>() ; paramsMap.put("name","小明"); paramsMap.put("html","<html>..."); post("https://10.0.4.147:8015/crcc",paramsMap); } }
