javascript - 为什么这个 XMLHttpRequest 导致 http 406

Question

它是一个 XMLHttpRequest 来获取一个 json 表单。我在 3 个不同的主机上测试了它:

• 本地主机:http 200
• 我的测试 VPS 主机:200
• 我的共享主机 godaddy:406

我已经一次又一次地比较标题。然后我一整天都在谷歌上搜索并阅读了很多文章..但仍然可以找出原因..这里对我来说很少有可疑之处:

• 请求 URL:h.t.t.p://example.com/oxwall/base/ajax-loader/component/?cmpClass=PHOTO_CMP_AjaxUpload&r=0.41719201277010143 -> 'oxwall' 是我的 php 应用程序，一个真正的目录，而 'base' 不是真正的直接。
• Godaddy 的某些配置不支持 XMLHttpRequest？
• json:我看到很多用 Json 报告的 406:

请给我一些线索，我需要调查什么。

Answer 1

http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html (查找406)

在您的回复中:

Content-Type:text/html; charset=iso-8859-1

在您的请求中:

Accept:application/json, text/javascript, */*; q=0.01

我猜你必须设置接受。如果您不使用 jQuery(未标记)，则 here是如何使用 vanilla JS 实现的:

xmlhttp.setRequestHeader("Accept"
  , "text/html");

您应该尝试在浏览器中打开 url，因为您需要向它发送值以查看它是否正常工作，您可以创建一个 html 文件，格式为 method=post action=your godaddy site。
