HTTP协议的接口测试中，使用到最多的就是GET请求与POST请求，其中POST请求有FORM参数提交请求与RAW请求，下面我将结合HttpClient来实现一下这三种形式：
一、GET请求: GET请求时，参数一般是写在链接上的，代码如下：
public void get(String url){
CloseableHttpClient httpClient = null;
HttpGet httpGet = null;
try {
httpClient = HttpClients.createDefault();
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
httpGet = new HttpGet(url);
httpGet.setConfig(requestConfig);
CloseableHttpResponse response = httpClient.execute(httpGet);
HttpEntity httpEntity = response.getEntity();
System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}finally{
try {
if(httpGet!=null){
httpGet.releaseConnection();
}
if(httpClient!=null){
httpClient.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
如果想把参数不写在链接上，单独的传进去，则可以这样：
public void get(String url, Map<String, String> params){
CloseableHttpClient httpClient = null;
HttpGet httpGet = null;
try {
httpClient = HttpClients.createDefault();
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
String ps = "";
for (String pKey : params.keySet()) {
if(!"".equals(ps)){
ps = ps + "&";
}
ps = pKey+"="+params.get(pKey);
}
if(!"".equals(ps)){
url = url + "?" + ps;
}
httpGet = new HttpGet(url);
httpGet.setConfig(requestConfig);
CloseableHttpResponse response = httpClient.execute(httpGet);
HttpEntity httpEntity = response.getEntity();
System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}finally{
try {
if(httpGet!=null){
httpGet.releaseConnection();
}
if(httpClient!=null){
httpClient.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
二、POST请求的表单提交方式，代码如下：
public void post(String url, Map<String, String> params){
CloseableHttpClient httpClient = null;
HttpPost httpPost = null;
try {
httpClient = HttpClients.createDefault();
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
httpPost = new HttpPost(url);
httpPost.setConfig(requestConfig);
List<NameValuePair> ps = new ArrayList<NameValuePair>();
for (String pKey : params.keySet()) {
ps.add(new BasicNameValuePair(pKey, params.get(pKey)));
}
httpPost.setEntity(new UrlEncodedFormEntity(ps));
CloseableHttpResponse response = httpClient.execute(httpPost);
HttpEntity httpEntity = response.getEntity();
System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}finally{
try {
if(httpPost!=null){
httpPost.releaseConnection();
}
if(httpClient!=null){
httpClient.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
三、 POST请求的RAW参数传递：
public void post(String url, String body){
CloseableHttpClient httpClient = null;
HttpPost httpPost = null;
try {
httpClient = HttpClients.createDefault();
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
httpPost = new HttpPost(url);
httpPost.setConfig(requestConfig);
httpPost.setEntity(new StringEntity(body));
CloseableHttpResponse response = httpClient.execute(httpPost);
HttpEntity httpEntity = response.getEntity();
System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}finally{
try {
if(httpPost!=null){
httpPost.releaseConnection();
}
if(httpClient!=null){
httpClient.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
