Failed to execute 'setRequestHeader' on 'XMLHttpRequest' [...] is not a valid HTTP header field value
提问by Marius Manastireanu
I am developing an application with AngularJS (client side) and Java (server side) using RESTful services (with Jersey).
我正在使用 RESTful 服务（使用 Jersey）开发带有 AngularJS（客户端）和 Java（服务器端）的应用程序。
In the client I have something like this
在客户端我有这样的事情
$http({
url : "/Something/rest/...",
method : "POST",
headers : {
...
'text' : text
}
});
on the server side my Java method header looks like this
在服务器端，我的 Java 方法标头如下所示
public JSONObject myMethod(@HeaderParam("text") String text [...]) throws JSONException
And I'm getting this error when trying to send a request
我在尝试发送请求时收到此错误
Error: Failed to execute 'setRequestHeader' on 'XMLHttpRequest': 'Some text here formatted with \n and \t' is not a valid HTTP header field value.
Is this because of the formatting? Is it because the text is quite long?
这是因为格式吗？是不是因为文字很长？
What should I change? Please guide me

Are you sending your 'text' in headers on purpose? This is in general not a place for doing this. For sending content through POST(or GET) you should use 'data' field. So:
您是故意在标题中发送“文本”吗？这通常不是执行此操作的地方。要通过 POST（或 GET）发送内容，您应该使用“数据”字段。所以：
$http({
url : "/Something/rest/...",
method : "POST",
data: {
...
'text' : text
}
});
,and on the server side similar change for getting your data from POST. You don't need and shouldn't mess with headers unless you know what you are doing.
，并在服务器端从 POST 获取数据的类似更改。除非您知道自己在做什么，否则您不需要也不应该弄乱标题。

I had faced this problem. Please make sure that in your code header name doesn't contain space. i.e. 'designId ' is invalid, as it contain space at end
我曾经遇到过这个问题。请确保您的代码标头名称中不包含空格。即“designId”无效，因为它在末尾包含空格
