SparkPost发送邮件异常

Question

Sparkpost发送邮件-我已经放置了spark post的jar文件，并遵循sparkpost开发人员提供的相同文件，但无法发送电子邮件。

    final String API_KEY = "xxxx"; 
    sparky.sendMessage("xyz@abc.com",  // from email
    "xxx@gmail.com",                   // to email
    "The subject of the message",      // subject of email
    "The text part of the email",      // text of email body
    "<b>The HTML part of the email</b>"); // Html text of email body


But getting this exception

    com.sparkpost.exception.SparkPostErrorServerResponseException: Unexpected server response ContentType(null) from https://api.sparkpost.com/api/v1/URI [scheme=null, userInfo=null, host=null, port=-1, path=transmissions, queryParams=[num_rcpt_errors=0], fragment=null] contentLength(0)

Answer 1

请使用maven或gradle依赖项尝试一次，尽管使用jar。当我从jcenter存储库中使用gradle时，我的问题就解决了。
