介面測試-自動化-Java實現-HttpUtil

標籤：

HttpUtil負責提供Http的Post方法，其核心的方法如下：

 /**     * Do POST request     * @param url     * @param parameterMap     * @return     * @throws Exception      */    public String doPost(String url, Map<?, ?> parameterMap) throws Exception {                /* Translate parameter map to parameter date string */        StringBuffer parameterBuffer = new StringBuffer();        if (parameterMap != null) {            Iterator<?> iterator = parameterMap.keySet().iterator();            String key = null;            String value = null;            while (iterator.hasNext()) {                key = (String)iterator.next();                if (parameterMap.get(key) != null) {                    value = (String)parameterMap.get(key);                } else {                    value = "";                }                                parameterBuffer.append(key).append("=").append(value);                if (iterator.hasNext()) {                    parameterBuffer.append("&");                }            }        }        //        System.out.println("POST parameter : " + parameterBuffer.toString());                URL localURL = new URL(url);                URLConnection connection = openConnection(localURL);        HttpURLConnection httpURLConnection = (HttpURLConnection)connection;                httpURLConnection.setDoOutput(true);        httpURLConnection.setRequestMethod("POST");        httpURLConnection.setRequestProperty("Accept-Charset", charset);        httpURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");        httpURLConnection.setRequestProperty("Content-Length", String.valueOf(parameterBuffer.length()));                OutputStream outputStream = null;        OutputStreamWriter outputStreamWriter = null;        InputStream inputStream = null;        InputStreamReader inputStreamReader = null;        BufferedReader reader = null;        StringBuffer resultBuffer = new StringBuffer();        String tempLine = null;                try {            outputStream = httpURLConnection.getOutputStream();            outputStreamWriter = new OutputStreamWriter(outputStream);                        outputStreamWriter.write(parameterBuffer.toString());            outputStreamWriter.flush();                        if (httpURLConnection.getResponseCode() >= 300) {                resultBuffer.append(httpURLConnection.getResponseCode());                throw new Exception("HTTP Request is not success, Response code is " + httpURLConnection.getResponseCode());            }                        inputStream = httpURLConnection.getInputStream();            inputStreamReader = new InputStreamReader(inputStream);            reader = new BufferedReader(inputStreamReader);                        while ((tempLine = reader.readLine()) != null) {                resultBuffer.append(tempLine);            }                    } finally {                        if (outputStreamWriter != null) {                outputStreamWriter.close();            }                        if (outputStream != null) {                outputStream.close();            }                        if (reader != null) {                reader.close();            }                        if (inputStreamReader != null) {                inputStreamReader.close();            }                        if (inputStream != null) {                inputStream.close();            }                    }        return resultBuffer.toString();    }

其實這也不是我自己寫的代碼，所以並麼有什麼特別好說的。我只知道，傳遞了URL 和 介面參數，使用Post方法獲得伺服器的結果。
