大家好！今天讓創(chuàng)意嶺的小編來大家介紹下關(guān)于https請求http接口的問題，以下是小編對此問題的歸納整理，讓我們一起來看看吧。

https能跨域調(diào)用http請求嗎

可以的，如果調(diào)用HTTP，地址欄不會出現(xiàn)小鎖，當然如果是JS代碼，有的瀏覽器會屏蔽掉的，所以建議還是使用HTTPS資源，詳細說明：HTTPS是嚴格加密傳輸，需要全站源碼HTTPS鏈接，不允許調(diào)用HTTP普通協(xié)議數(shù)據(jù)，其中包括：JS、CSS、png、gif、jpg 等任何HTTP協(xié)議普通資源的存在，如果調(diào)用地址欄不會顯示小鎖圖標，超級鏈接除外。

使用https訪問http/https通信協(xié)議，需要哪些配置文件

項目里需要訪問其他接口，通過http/https協(xié)議。我們一般是用HttpClient類來實現(xiàn)具體的http/https協(xié)議接口的調(diào)用。
// Init a HttpClient
HttpClient client = new HttpClient();
String url=http://www.xxx.com/xxx;
// Init a HttpMethod
HttpMethod get = new GetMethod(url);
get.setDoAuthentication(true);
get.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler(1, false));
// Call http interface
try {
client.executeMethod(get);
// Handle the response from http interface
InputStream in = get.getResponseBodyAsStream();
SAXReader reader = new SAXReader();
Document doc = reader.read(in);
} finally {
// Release the http connection
get.releaseConnection();
}
以上代碼在通過普通的http協(xié)議是沒有問題的，但如果是https協(xié)議的話，就會有證書文件的要求了。一般情況下，是這樣去做的。
// Init a HttpClient
HttpClient client = new HttpClient();
String url=https://www.xxx.com/xxx;
if (url.startsWith("https:")) {
System.setProperty("javax.net.ssl.trustStore", "/.sis.cer");
System.setProperty("javax.net.ssl.trustStorePassword", "public");
}
于是，這里就需要事先生成一個.sis.cer的文件，生成這個文件的方法一般是先通過瀏覽器訪問https://，導出證書文件，再用JAVA keytool command 生成證書
# $JAVA_HOME/bin/keytool -import -file sis.cer -keystore .sis.cer
但這樣做，一比較麻煩，二來證書也有有效期，過了有效期之后，又需要重新生成一次證書。如果能夠避開生成證書文件的方式來使用https的話，就比較好了。
還好，在最近的項目里，我們終于找到了方法。
// Init a HttpClient
HttpClient client = new HttpClient();
String url=https://www.xxx.com/xxx;
if (url.startsWith("https:")) {
this.supportSSL(url, client);
}
用到了supportSSL(url, client)這個方法，看看這個方法是如何實現(xiàn)的。
private void supportSSL(String url, HttpClient client) {
if(StringUtils.isBlank(url)) {
return;
}
String siteUrl = StringUtils.lowerCase(url);
if (!(siteUrl.startsWith("https"))) {
return;
}

try {
setSSLProtocol(siteUrl, client);
} catch (Exception e) {
logger.error("setProtocol error ", e);
}
Security.setProperty( "ssl.SocketFactory.provider",
"com.tool.util.DummySSLSocketFactory");
}
private static void setSSLProtocol(String strUrl, HttpClient client) throws Exception {

URL url = new URL(strUrl);
String host = url.getHost();
int port = url.getPort();
if (port <= 0) {
port = 443;
}
ProtocolSocketFactory factory = new SSLSocketFactory();
Protocol authhttps = new Protocol("https", factory, port);
Protocol.registerProtocol("https", authhttps);
// set https protocol
client.getHostConfiguration().setHost(host, port, authhttps);
}
在supportSSL方法里，調(diào)用了Security.setProperty( "ssl.SocketFactory.provider",
"com.tool.util.DummySSLSocketFactory");
那么這個com.tool.util.DummySSLSocketFactory是這樣的：
訪問https 資源時,讓httpclient接受所有ssl證書,在weblogic等容器中很有用
代碼如下:

public Socket createSocket(String host, int port) throws IOException,

然后按如下方式使用HttpClient
Protocol myhttps = new Protocol("https", new MySecureProtocolSocketFactory (), 443);
Protocol.registerProtocol("https", myhttps);
HttpClient httpclient=new HttpClient();
