httpClient忽略https的证书认证

忽略https证书认证代码:

一、Get请求

接口地址及参数:https://xxx.xxx.com/api/v3/technicians?input_data={“list_info”:{“search_fields”:{“email_id”:“wjjia@iflytek.com”}}}

postman调用示例:

在这里插入图片描述

java代码实现:

OAPropUtil.technician_info_url = https://xxx.xxx.com/api/v3/technicians

String url = OAPropUtil.technician_info_url+"?input_data="+ URLEncoder.encode(JSON.toJSONString(listInfo),"UTF-8");

headerMap.put("authtoken", "12345");
            headerMap.put("Content-type", "application/json;charset=UTF-8");
            String resultStr = OAUtil.getWithHeaderIgnoreSSL(url,headerMap);
  
  public static String getWithHeaderIgnoreSSL(String url,Map<String, String> headerMap) throws Exception {
        CloseableHttpClient httpclient = createHttpClientWithNoSsl();
        HttpGet get = new HttpGet(url);
        // 设置请求头信息
        if (headerMap != null && headerMap.size() > 0) {
            for (String key : headerMap.keySet()) {
                get.addHeader(key, headerMap.get(key));
            }
        }
        RequestConfig requestConfig = RequestConfig.custom().setConnectionRequestTimeout(1000)
                .setSocketTimeout(20000).setConnectTimeout(3000).build();
        get.setConfig(requestConfig);
        HttpResponse response = httpclient.execute(get);
        try {
            int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode == HttpStatus.SC_OK) {
                //4.解析响应,获取数据
                HttpEntity entity = response.getEntity();
                if (entity != null) {
                    return EntityUtils.toString(entity,"UTF-8");
                } else {
                    System.out.println("statusCode[" + statusCode + "],url[" + url + "]");
                }
            }
