使用HttpClient4实现API测试实战(1)
1、引言
API测试过程中,有些API接口可能需要上传附件,而且是多个附件,本文主要是解决API测试过程中的多附件上传问题。
当然,你也可以将本文当作
使用HttpClient模拟HTTP实现多附件上传的文章来阅读。
2、更新测试项目
2.1 添加项目依赖
httpmime-4.2.1.jar
2.2 修改HttpClient帮助类HttpClientUtil
添加下面方法
public static String doPostUpload(String url, List<BasicNameValuePair> datas, List<String> files) {
try {
// 组装提交信息
MultipartEntity reqEntity = new MultipartEntity();
for(BasicNameValuePair data : datas) {
reqEntity.addPart(data.getName(), new StringBody(data.getValue(), "text/plain", Charset.forName("UTF-8")));
}
for(String file : files) {
reqEntity.addPart("file", new FileBody(new File(file)));
}
// 设置提交信息
HttpPost httppost = new HttpPost(url);
httppost.setEntity(reqEntity);
HttpResponse httpResponse = httpClient.execute(httppost);
// 若状态码为200 ok
if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
// 取出回应字串
String strResult = EntityUtils.toString(httpResponse.getEntity());
System.out.println("doPostJson response[" + url + "]: \n" + strResult);
return strResult;
} else {
System.out.println("doPost Error Response[" + url + "]: \n" + httpResponse.getStatusLine().toString());
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
2.3 修改API帮助类ApiUtil
增加多附件测试方法
// 发布带附件信息
public static boolean uploadMessage(String status, List<String> files) {
return uploadMessage(status, null, files);
}
public static boolean uploadMessage(String status, String groupId, List<String> files) {
List<BasicNameValuePair> params = new ArrayList<BasicNameValuePair>(0);
params.add(new BasicNameValuePair("account_token", getToken()));
params.add(new BasicNameValuePair("status", status));
if(groupId!=null) {
params.add(new BasicNameValuePair("group_id", groupId));
}
String xml = HttpClientUtil.doPostUpload(API_URL + "/messages/upload", params, files);
if (!hasText(xml)) {
return false;
}
if (xml.indexOf("errorCode") == -1) {
return true;
} else {
return false;
}
}
2.4 修改ApiUtil中的测试方法
修改后的测试代码如下
public static void main(String[] argus) {
login("[email protected]", "password");
List<String> files = new ArrayList<String> (0);
files.add("c:\\myimage.jpg");
files.add("c:\\dulala.txt");
uploadMessage("测试附件和图片上传1", "151", files);
}
2.5 运行测试
运行测试代码,带附件信息发布成功;
