問題描述

我們可以通過 json 攔截器將 JSON 發送到 Struts2 動作.http:///tech.learnerandtutor.com/send-json-object-to-struts-2-action-by-jquery-ajax/.

We can send JSON to Struts2 actions by json interceptor. There is good sample at http://tech.learnerandtutor.com/send-json-object-to-struts-2-action-by-jquery-ajax/.

json 攔截器要求請求 content type 為 application/json 或 application/json-rpc這個可以在我們直接使用Ajax的時候設置，比如:

The json interceptor requires that the requests content type be application/json or application/json-rpc this can be set when we directly use Ajax like:

$.ajax({
    url: "writeJSON.action",
    data: data1,
    dataType: 'json',
    contentType: 'application/json',

但我們正在使用 struts 2 jquery 插件標簽(sj:a 和 sj:submit ...)為我們管理 ajax 調用.

But we are using struts 2 jquery plugin tags (sj:a and sj:submit ...) which manage ajax calls for us.

有什么方法可以用這些標簽設置contentType.

Is there any way that we can set the contentType with these tags.

我沒有找到這個標簽屬性.

I did not find tag properties for this.

如果沒有實現，有沒有其他方法可以設置.

If it is not implemented is there any other way to set it.

推薦答案

您應該將 Content-type: application/json 標頭設置為 $.ajax().

You should set Content-type: application/json header to xhr object that is used by the $.ajax().

$.ajax({
    url: "writeJSON.action",
    data: data1,
    dataType: 'json',
    contentType: 'application/json',

插件使用$.ajaxSubmit()，這種提交應該被淘汰，因為它不適用于json數據.

The plugin is using $.ajaxSubmit(), this kind of submission should be eliminated because it doesn't work with json data.
