java - 在/share 和/alfresco 之间的 POST 请求上的 Alfresco 随机 HTTP 400

Question

我在户外获取 POST HTTP 请求时遇到问题。

我使用 YAHOO.asyncRequest 向/share/proxy/alfresco/... 发送请求，有时我会收到 400 响应代码。我总是发送相同的请求和相同的参数，所以问题不在这里。我调试了 Alfresco 的代码，发现 RemoteClient 将 HTTP 请求发送到/alfresco/s/...?ALF_TICEKT=...，但如果发生错误，我无法在 Alfresco 端看到请求。收到响应 400。

我 tcpdump 了请求，如果一切正常，我可以看到:

POST /alfresco/s/.../institution-registration?close=true&instID=2&alf_ticket=TICKET_1eb2ac478ba6b2389c831de9014d3ab4564e4855 HTTP/1.1

如果出现 HTTP 400:

我发现在 GET 请求中它不会发生。有什么建议吗？

我在 Alfresco 论坛上问了同样的问题，得到了答案:

将 YAHOO 请求更改为 Ajax 请求并且成功了。
