Azure作為微軟的公有云平臺(tái)，提供了非常豐富的SDK和API讓開發(fā)人員可以非常方便的調(diào)用的各項(xiàng)服務(wù)，目前除了自家的.NET, Java, Python, nodeJS, Ruby，PHP等語(yǔ)言都提供支持，詳細(xì)的文檔說(shuō)明請(qǐng)參考：

站在用戶的角度思考問(wèn)題，與客戶深入溝通，找到秀山土家族苗族網(wǎng)站設(shè)計(jì)與秀山土家族苗族網(wǎng)站推廣的解決方案，憑借多年的經(jīng)驗(yàn)，讓設(shè)計(jì)與互聯(lián)網(wǎng)技術(shù)結(jié)合，創(chuàng)造個(gè)性化、用戶體驗(yàn)好的作品，建站類型包括：網(wǎng)站建設(shè)、成都網(wǎng)站制作、企業(yè)官網(wǎng)、英文網(wǎng)站、手機(jī)端網(wǎng)站、網(wǎng)站推廣、申請(qǐng)域名、虛擬主機(jī)、企業(yè)郵箱。業(yè)務(wù)覆蓋秀山土家族苗族地區(qū)。

https://azure.microsoft.com/en-us/documentation/

然而在使用過(guò)程中，以Java語(yǔ)言為例，在初始調(diào)用Azure SDK/API的時(shí)候大家會(huì)碰到類似下面的錯(cuò)誤：

[WARN] ServiceBusContract - com.sun.jersey.api.client.ClientHandlerException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target <com.sun.jersey.api.client.ClientHandlerException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target>com.sun.jersey.api.client.ClientHandlerException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

    at com.sun.jersey.client.urlconnection.URLConnectionClientHandler.handle(URLConnectionClientHandler.java:151)

    at com.microsoft.windowsazure.core.pipeline.jersey.ClientFilterRequestAdapter.handle(ClientFilterRequestAdapter.java:36)

    at com.sun.jersey.api.client.Client.handle(Client.java:648)

。。。。。。

 

其實(shí)這個(gè)錯(cuò)誤并不是Azure的問(wèn)題，如果大家搜一搜就知道，只要是你用Java去訪問(wèn)https的網(wǎng)站或者服務(wù)，都會(huì)碰到類似的錯(cuò)誤，最根本的原因是CNNIC所頒發(fā)的證書并不被JDK所認(rèn)可，其中原因大家應(yīng)該懂得：）今年5月份，Google和Firefox等多家互聯(lián)網(wǎng)公司更是將直接拒絕接受CNNIC所頒發(fā)的證書:

 

https://threatpost.com/google-drops-trust-in-chinese-certificate-authority-cnnic/111974/

 

言歸正傳，如何解決這個(gè)問(wèn)題？

 

1. 等待Oracle/Google/Mozilla等等組織信任CNNIC，算了，洗洗睡吧

2. 使用Java的TrustManager忽略所有的SSL請(qǐng)求的證書，僅僅用于開發(fā)測(cè)試，限于篇幅不做介紹了

3. 導(dǎo)入目標(biāo)網(wǎng)站的證書，然后在開始調(diào)用之前，指定keystore就ok了，本文介紹下該方法

 

在你的IDE環(huán)境中導(dǎo)入如下文件獲取目標(biāo)網(wǎng)站的證書，該程序是Sun（已經(jīng)被Oracle收了）的一位大牛寫的，名字沒(méi)有查到，我只是引用一下，不是我寫的，對(duì)其貢獻(xiàn)表示尊重：

Added certificate to keystore 'jssecacerts' using alias 'www.windowsazure.cn-1'

 

你在程序運(yùn)行的當(dāng)前目錄會(huì)生成一個(gè)jssecacerts文件，你可以將它放到你的jre的lib\security目錄，也可以放在任意位置，然后再你的程序調(diào)用API之前指定TrustStore的位置：

 

 

System.setProperty("javax.net.ssl.trustStore","E:\\DevSpace\\jssecacerts");

 

我的例子如下：

 

Enjoy！
