[Solved] HttpPost Call https Interface error: PKIX path building failed

When using HttpPost to call the https interface, report an error: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to the requested target,

Here is a solution below:

     * HttpClient error: ”SSLPeerUnverifiedException: peer not authenticated”
     * You don't need to import SSL 
     * @param base
     * @return
    public static HttpClient wrapClient(HttpClient base) {
        try {
            SSLContext ctx = SSLContext.getInstance("TLS");
            X509TrustManager tm = new X509TrustManager() {

                public void checkClientTrusted(java.security.cert.X509Certificate[] arg0, String arg1)
                        throws java.security.cert.CertificateException {
                    // TODO Auto-generated method stub


                public void checkServerTrusted(java.security.cert.X509Certificate[] arg0, String arg1)
                        throws java.security.cert.CertificateException {
                    // TODO Auto-generated method stub


                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    // TODO Auto-generated method stub
                    return null;
            ctx.init(null, new TrustManager[]{tm}, null);
            SSLConnectionSocketFactory ssf = new SSLConnectionSocketFactory(ctx, NoopHostnameVerifier.INSTANCE);
            CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(ssf).build();
            return httpclient;
        } catch (Exception ex) {
            return HttpClients.createDefault();

Calling wrapclient method to generate httpclient can avoid problems.

        httpClient = (CloseableHttpClient) wrapClient(httpClient);
        CloseableHttpResponse response = null;

        String[] zx = new String[]{"qyjbxx", "dwjbxx"};
        for (String s : zx) {
            JSONObject jsonObject1 = JSONObject.fromObject("{\n" +

                    organizationNum = organizationNum + totalElements;

[Solved] JAVA HttpClient Send Https request certificate error:PKIX path building failed:

Recently, when using httpclient to connect with the third-party SMS interface, a certificate invalidation error was reported during the local test.

1. Post request of Encapsulated HttpClient:

public static Map<String, Object> postReq(String URL, Map<String, Object> paramMap, Map<String, String> headers) throws Exception {
        Map<String, Object> map = new HashMap<String, Object>();

        RequestConfig requestConfig = RequestConfig.custom()
                .setConnectTimeout(2000) // Set the connection timeout, in milliseconds
                .setSocketTimeout(5000) // timeout for requesting data, in milliseconds
        HttpRequestRetryHandler myRetryHandler = new HttpRequestRetryHandler() {
            public boolean retryRequest(IOException exception, int executionCount, HttpContext context) {
                return false;

        try (CloseableHttpClient client = HttpClients.custom()
                .build()) {

            HttpPost httpPost = new HttpPost(URL);
            if (paramMap != null) {
                JSONObject paramJson = new JSONObject(paramMap);
                StringEntity paramEntity = new StringEntity(paramJson.toString(), "UTF-8");
                paramEntity.setContentType("application/json; charset=utf-8");

            if (headers != null && !headers.isEmpty()) {
                for (String key : headers.keySet()) {
                    String value = headers.get(key);
                    httpPost.setHeader(key, value);

            CloseableHttpResponse response = client.execute(httpPost);

            HttpEntity entity = response.getEntity();

            if (entity != null) {
                String responseStr = EntityUtils.toString(entity, "UTF-8");
                if (responseStr.isEmpty()) {
                    responseStr = "{}";

                int statusCode = response.getStatusLine().getStatusCode();
                if (HttpServletResponse.SC_OK == statusCode) {
                    try {
                        JSONObject dataJson = (JSONObject) JSONObject.parse(responseStr);
                        map = new HashMap<>(dataJson);
                    } catch (Exception e) {
                        map.put("reponse", responseStr);
                } else {
                    return map;
        return map;

However, an error will be reported when accessing some self signed HTTPS requests. This problem is caused by the invalid link certificate, because the self signed certificate will be recognized as an unsafe link.

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

2. Solutions

  1. Set the security certificate of jdk according to the online method -> No work
  2. Set maven to ignore the certificate checksum -> no work
  3. Yml file configuration httpclient ignore SSL checksum, seems to have no effect.
  4. Finally used the method of modifying the code, the principle is also to ignore the certificate checksum, but the code produced the effect, it is estimated that the construction is related to the Httpclient.


Modify the original code

// Ignore SSL Security Certification
**SSLConnectionSocketFactory scsf = new SSLConnectionSocketFactory(
        SSLContexts.custom().loadTrustMaterial(null, new TrustSelfSignedStrategy()).build(),

try (CloseableHttpClient client = **HttpClients.custom().setSSLSocketFactory(scsf)**
        .build()) {

[Solved] Git Clone Error: error setting certificate verify locations


When using git clone to clone an item on GitHub or gitee, the following error is reported:

error setting certificate verify locations:

CAfile: E:/Git/mingw64/ssl/certs/ca-bundle. crt

CApath: none


According to the error prompt, there is an error in setting the certificate verification location, that is, the certificate file path is wrong.

When cloning a remote project, the security certificate will be verified first. If the local security certificate file cannot be found, an error will be reported.

This is why this error will not be reported when cloning projects on gitlab, because gitlab is generally built on the intranet and does not need to verify the security certificate.

Path errors often occur because the local Git is installed green, that is, it is directly extracted and used.

In this way, the path of the certificate file is still the path on the original machine. If the path of the new machine is inconsistent, the path error will be caused.


For the above analysis, there are two solutions:

  • Modify certificate file path (recommended)
  • Turn off certificate verification

Turning off certificate verification may cause security problems. It is recommended to modify the certificate file path.

Modify certificate file path

There are two ways:

  • Execute the configuration command (recommended)
  • Modify the configuration file

The essence of these two methods is to modify the configuration file. However, some misoperations may occur when modifying the file, and the operation is more cumbersome. It is recommended to execute the configuration command.

Execute configuration command

git config --system http.sslcainfo "Git安装路径/mingw64/ssl/certs/ca-bundle.crt"

Modify profile

Git’s system configuration files are located at: git installation path \etc\gitconfig

Modify the path in the file as shown in the figure to git installation path /mingw64/ssl/certs/ca-bundle.crt save again.

Turn off certificate verification

git config --system http.sslverify false

This method may cause git security problems and is not recommended.

Python: How to Disable InsecureRequestWarning error

Python Disable InsecureRequestWarning error

Send HTTPS requests using Python 3 requests. When SSL authentication is turned off (verify = false):

import requests
response = requests.get(url='', verify=False)

Error Messages:

InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings


import urllib3

from requests.packages.urllib3.exceptions import InsecureRequestWarning

PS: as shown below, disable_warnings() will disable all warning types.

def disable_warnings(category=exceptions.HTTPWarning):
    Helper for quickly disabling all urllib3 warnings.
    warnings.simplefilter("ignore", category)

Python requests Error: ConnectionError: (‘Connection aborted.‘, error(104, ‘Connection reset by peer‘))

Python requests error

ConnectionError: (‘Connection aborted.’, error(104, ‘Connection reset by peer’))

There are two possible causes

1. Requests are too frequent, resulting in requests being rejected


Set a sleep time for each request, such as
time sleep(1)

2. The interface has authentication or anti crawling mechanism. It is recognized that it is accessed by Python terminal, and the access is rejected


Set user agent in request header to bypass authentication


headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko',"Content-Type": "application/json"}

The reason for the error is: java.net.Socketexception: permission denied , which is obviously a network permission problem. The reason for this problem is that the Linux operating system does not allow non root users to use ports less than 1024.

2. Solutions

1. Use the root account to start Tomcat
2. Change the port number to a port number greater than 1024, but add the port number to the URL request
3. Change the port number to a port number greater than 1024, and use iptables to forward port 443 to the configured port. The command is as follows:

#Execute the commands under the root
# Mapping port 443 to 8443
iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 8443

Local repository upload to remote repository error: failed to push some refs to ‘https://hub.fastgit.org/zhizhangxuezhang/ui-test.git‘

There is an error in pushing from the local warehouse to the remote warehouse (rejected) because the code of the remote warehouse has been modified directly in the remote warehouse. At this time, the code of the local warehouse is different from that of the remote warehouse, so you must update the code of the local warehouse (Pull) first and then submit (push)

Error log in idea for this problem:

error log in Git bash:

at this time, you can only pull to update your local warehouse and then push to the remote warehouse, but you will find that you will also report an error when you pull to the local warehouse

at this time, your pull command should be changed to the following command, That is, just add a parameter to ignore the history (because the two branches are caused by different versions)

git pull origin master --allow-unrelated-histories

PHP function file_ get_ Contents() reports an error when using HTTPS protocol: SSL operation failed


file_ get_ The contents () function is used to read the contents of a file into a string. It is one of the commonly used functions to read the contents of a file.

But sometimes file is used on the server_ get_ When the contents() function requests the URL file of HTTPS protocol, an error will be reported, and the file content cannot be read correctly,


The server is not properly configured with HTTPS certificate

Solution: (three solutions)

Method 1:

Download HTTPS certificate to server

The server downloads this certificate, http://curl.haxx.se/ca/cacert.pem
Php.ini configuration
openssl.cafile = “/ etc/SSL/certs/cacert. PEM”// the path where you actually download the certificate
Restart PHP

Method 2:

Use the curl function to process HTTPS parameters and obtain the file content

function getSSLPage($url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSLVERSION,3); 
    $result = curl_exec($ch);
    return $result;


Method 3:

Make file_ get_ The contents() function skips HTTPS authentication

$stream_opts = [
    "ssl" => [

$response = file_get_contents("https://xxx.xxx.xxx",false,stream_context_create($stream_opts));

  It is recommended to use curl function instead of file in development_ get_ Contents() function.
