云代码超过6k的数据无法post，求证

[C11]

用curl调用rest api，post一个6k的json，发现http 1.1/100 continue导致curl停止。

修改curl命令，用-H "Expect:"或者-0，迫使curl在收到response前发送全部文本。avosapps.com报错：

content-type: application/json
Content-Length: 6001

< HTTP/1.1 502 Bad Gateway
< Server: nginx
< Date: Wed, 05 Aug 2015 01:57:04 GMT
< Content-Type: text/html
< Content-Length: 166
< Connection: keep-alive

貌似avosapps.com无法接受大文本post，求证。

不至于 6k 长度就不行了。

麻烦你贴下 curl 命令，注意隐藏 appId 和 appKey

和curl无关，我们全球10个国家30个节点往leancloud post一个流量统计json，工作了一个多月，前天开始全部停止工作。检查下来就是因为content-length太长，leancloud报错502。

我们先在localhost测试nodejs代码。功能就是把post的json保存到leancloud，没有其他逻辑。

json数据5.9K

ls -lh vnstat.json
-rw-r--r-- 1 charleswang staff 5.9K Aug 6 08:02 vnstat.json

在本地用curl发送数据可以通过，登录leancloud.cn控制台可以看到数据。

curl -v -H "content-type:application/json" localhost:3000/vnstat -d @vnstat.json
* Hostname was NOT found in DNS cache
* Trying ::1...
* Connected to localhost (::1) port 3000 (#0)

POST /vnstat HTTP/1.1
User-Agent: curl/7.37.1
Host: localhost:3000
Accept: /
content-type:application/json
Content-Length: 6002
Expect: 100-continue

< HTTP/1.1 100 Continue
< HTTP/1.1 200 OK

< Date: Thu, 06 Aug 2015 00:05:52 GMT
< Connection: keep-alive
< Transfer-Encoding: chunked
<
* Connection #0 to host localhost left intact

随后用avoscloud deploy后测试，无法发送数据，报错502 bad gateway。

你好，我在我自己的测试应用尝试了，3.2MB 的 json 没有问题，不过为了上传大附件，代码有一点修改：

app.js 中间件修改

app.use bodyParser.json({limit: '10000kb'})

测试过程：

[chenwei@wchen-mbp ~]$ ls -alh Downloads/top.json
-rw-r-----@ 1 chenwei  staff   3.2M  8  6 17:15 Downloads/top.json
[chenwei@wchen-mbp ~]$ curl -X POST http://leanengine-unit-test.avosapps.com/postJson -H "Content-Type:application/json" -d @Downloads/top.json -v | more

你也可以向 http://leanengine-unit-test.avosapps.com/postJson 来 post json 字符串，他会原样返回。最大 10MB

原来如此啊，长知识！多谢高手相助，解决问题。
