TTP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：
publicvoidget(String url){
CloseableHttpClient httpClient =null;
HttpGet httpGet =null;
try{
httpClient = HttpClients.createDefault();
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
httpGet =newHttpGet(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：
publicvoidget(String url, Map 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 =newHttpGet(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:
publicvoidpost(String url, Map params){
CloseableHttpClient httpClient =null;
HttpPost httpPost =null;
try{
httpClient = HttpClients.createDefault();
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
httpPost =newHttpPost(url);
httpPost.setConfig(requestConfig);
List ps =newArrayList();
for(String pKey : params.keySet()) {
ps.add(newBasicNameValuePair(pKey, params.get(pKey)));
}
httpPost.setEntity(newUrlEncodedFormEntity(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
publicvoidpost(String url, String body){
CloseableHttpClient httpClient =null;
HttpPost httpPost =null;
try{
httpClient = HttpClients.createDefault();
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
httpPost =newHttpPost(url);
httpPost.setConfig(requestConfig);
httpPost.setEntity(newStringEntity(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();
}
}
}
