<html> <head> <meta charset="ISO-8859-1"> <title>Add Comment JIRA REST API</title> <script type="text/javascript"> function addComment() { var xhttp = new XMLHttpRequest(); var commentJson = '{"body" : “adding comment to the task from client side javascript code”}'; xhttp.onreadystatechange = function() { if (xhttp.readyState == 4) { document.getElementById("demo").innerHTML =xhttp.responseText; } }; xhttp.open("POST", "URL",true); xhttp.setRequestHeader("Content-type", "application/json"); xhttp.setRequestHeader("X-Atlassian-Token", "nocheck"); xhttp.setRequestHeader('Authorization', 'Basic'+btoa('username:password')); xhttp.send(commentJson); } </script> </head> <body> <h2>Adding Comment</h2> <button type="button" onclick="addComment()">Add Comment</button> <p id="demo"> </p> </body> </html>

Seems like you transferring some data that is not in valid format. 似乎您正在传输某些格式无效的数据。 This mean you need to use JSON.Stringify() or encode the json data in UTF-8 . 这意味着您需要使用JSON.Stringify()或以UTF-8编码json数据。 Probably JSON.Stringify() would solve this. 大概JSON.Stringify()可以解决这个问题。

This line: 这行：
var commentJson = '{"body" : “adding comment to the task from client side javascript code”}';
...has the wrong kind of double quote marks around the second internal string. ...在第二个内部字符串周围有错误的双引号。 Make sure all of the double quote marks are straight, not left or right double quotes, like this: 确保所有双引号都是直的，而不是左或右双引号，如下所示：
var commentJson = '{"body" : "adding comment to the task from client side javascript code"}';
In addition, you might have to make sure your character encoding matches, as whiterabbitj suggested, but first you have to deal with using the wrong quote marks. 另外，您可能必须确保您的字符编码匹配，如whiterabbitj建议的那样，但是首先您必须处理使用错误的引号。 It looks like you're sending in UTF-8, but the server is treating your data as ISO-8859-1. 看起来您正在使用UTF-8发送，但是服务器将您的数据视为ISO-8859-1。
