我有一个错误＆＃34; RangeError：RangeError＆＃34;当我通过我的网络服务发布文件时。

Sinatra版本：sinatra（1.4.7）
Ruby版本：2.3.1

请参阅下面的错误堆栈：

请参阅下面的代码：

require 'rubygems'
require 'sinatra'

set :bind, '127.0.0.1'
set :port, '4567'

post '/test' do

  body "Hello"
  status 202
  return

end

请参阅下面发布的文件：

{
  "caller":"TEST",
  "c1": [ { "a" : ["b" ] } ],
  "c2": [ { "a" : ["b" ] } ],
  "c3": [ { "a" : ["b" ] } ],
  "c4": [ { "a" : ["b" ] } ],
  "c5": [ { "a" : ["b" ] } ],
  "c6": [ { "a" : ["b" ] } ],
  "c7": [ { "a" : ["b" ] } ],
  "c8": [ { "a" : ["b" ] } ],
  "c9": [ { "a" : ["b" ] } ],
  "c10": [ { "a" : ["b" ] } ],
  "c11": [ { "a" : ["b" ] } ],
  "c12": [ { "a" : ["b" ] } ],
  "c13": [ { "a" : ["b" ] } ],
  "c14": [ { "a" : ["b" ] } ],
  "c15": [ { "a" : ["b" ] } ],
  "c16": [ { "a" : ["b" ] } ],
  "c17": [ { "a" : ["b" ] } ],
  "c18": [ { "a" : ["b" ] } ],
  "c19": [ { "a" : ["b" ] } ],
  "c20": [ { "a" : ["b" ] } ],
  "c21": [ { "a" : ["b" ] } ],
  "c22": [ { "a" : ["b" ] } ],
  "c23": [ { "a" : ["b" ] } ],
  "c24": [ { "a" : ["b" ] } ],
  "c25": [ { "a" : ["b" ] } ]
}

请参阅下面用于发布我的文件的命令：

curl -v -H 'Accept: application/text' -X POST http://127.0.0.1:4567/test -d @$1

我认为问题是JSON结构。

我尝试在PHP服务器，Python和Java服务器中发布这个JSON，它可以工作。

数组数量的限制可能是由于Sinatra框架。当我发布一个包含49个阵列的文件时，它可以正常工作，但是超过50个就会失败。

提前致谢。

正如@Greg 提到的，为了解决这个问题，我只需要添加标题 -H 'Accept: application/json' -H 'Content-Type: application/json' 到查询
