Grails JSON 最大长度
我知道 JSON 字符串通常在 PHP 上的 Apache 中定义最大长度，但是使用 TomCat 在 Grails 中定义的 JSON 字符串的最大长度在哪里？
我发送的 JSON 字符串长度为 13,636 个字符，但是我可以将其缩短很多（尽管我们在测试时我不想这样做） - 而且，我们将来可能会通过 JSON 发送图像，我已经读取需要 Base64 编码，因此需要相当大的开销。如果我们要做这样的事情，那么我担心如果这个限制导致了问题，那么我们现在就应该克服它。
如果没有限制，那么也许我做错了什么。我有有限数量的域对象，我使用 domainInstance as grails.converters.deep.JSON 将其编码为 JSON - 这是使用 for 循环完成的，并且每次JSON 字符串附加到 StringBuilder
然后我使用 render(stringBuilder.toString()) 在视图中渲染 StringBuilder，第一个 JSON 字符串很好，但第二个是接近尾部时被截断。如果我要估计的话，我会说我得到了 StringBuilder 总长度的 80% 左右。
编辑/解决方案：抱歉，伙计们&女孩们，我注意到，当我在页面上查看源代码时，我得到了完整的 JSON 字符串，但是当我只查看页面时，它被截断了。这是一个奇怪的错误，不过我会接受关于为什么它被截断的答案。谢谢。
I am aware that JSON strings often have a max length defined in either Apache on PHP, however where is the max length for JSON strings defined in Grails using TomCat?
The JSON string I am sending is 13,636 characters in length, however I can shorten it a lot (although I don't want to while we're testing) - also, we may be sending images via JSON in the future which I've read requires base64 encoding and thus a considerable overhead. If we were to do such a thing then I am worried that if this limit is causing problems, it's something we should overcome now.
If there is no limit, then perhaps I am doing something wrong. I have a finite amount of domain objects that I am encoding as JSON using domainInstance as grails.converters.deep.JSON - this is done using a for loop and each time the JSON string is appended to a StringBuilder
I then render the StringBuilder in a view using render(stringBuilder.toString()) and the first JSON string is fine, however the second is truncated near to the end. If I were to guestimate I'd say I am getting around 80% of the total length of the StringBuilder.
EDIT/SOLUTION: Apologies guys & girls, I've noticed that when I view source on the page I get the complete JSON string, however when I just view the page it's truncated. It's an odd error, I'll accept answers on why it's truncated, though. Thanks.

Tomcat 中的 POST 请求有一个最大大小，如果您开始发送巨大的 JSON/Base64 图像请求（就像您提到的那样），稍后您可能会担心这个问题。
tomcat 中的默认值为 2,097,152 字节 (2 MB)；可以通过在 server.xml 中设置
maxPostSize属性来更改它。来自文档（对于
maxPostSize在 Tomcat 7 中）：如果您要将 Grails war 部署到独立的 Tomcat 实例，那么配置起来非常简单。但是，如果您使用 tomcat 插件。如果是我，我可能会使用 war 而不是 grails run-app 来运行大文件测试。
There is a maximum size in Tomcat for POST requests, which you may be concerned with later if you start sending huge JSON / Base64 image requests (like you mentioned).
The default value in tomcat is 2,097,152 bytes (2 MB); it can be changed by setting the
maxPostSizeattribute of the<Connector>in server.xml.From the docs (for
maxPostSizein Tomcat 7):This is pretty straightforward to configure if you're deploying a Grails war to a standalone Tomcat instance. However, I can't find much about actually configuring server.xml if you're using the tomcat plugin. If it were me, I'd probably just run large-file tests using the war instead of with grails run-app.
