解析json多部分表单有问题的Rails ?

I'm having a bit of trouble understudying why Rails 3.2.6 is parsing a multipart POST request that contains json.

在研究Rails 3.2.6解析包含json的多部分POST请求时，我遇到了一点麻烦。

The 'offending' curl command:

“冒犯”curl命令:

curl -i -X POST --silent http://localhost:3000/foo.json --form foo='{"name":"bar"};type=application/json'

Rails interprets as:

Rails解释为:

p params[:foo] #=> "{\"name\":\"bar\"}"

Note how the value is a string, not a hash (of parsed JSON).

注意该值是一个字符串，而不是一个散列(解析JSON)。

The headers sent by curl seem correct:

curl发送的头部看起来是正确的:

> POST /foo.json HTTP/1.1
> User-Agent: curl/7.21.4 (universal-apple-darwin11.0) libcurl/7.21.4 OpenSSL/0.9.8r zlib/1.2.5
> Host: localhost:3000
> Accept: */*
> Content-Length: 208
> Expect: 100-continue
> Content-Type: multipart/form-data; boundary=----------------------------959d0620faa3

The multipart's type also seems to be correct:

多重部分的类型似乎也是正确的:

------------------------------959d0620faa3
Content-Disposition: form-data; name="foo"
Content-Type: application/json

{"name":"bar"}
------------------------------959d0620faa3--

Could someone help me understand the best way to get to a place where params[:foo] returns the parsed json hash, as opposed to its string representation?

有人能帮我理解到解析json散列(而不是它的字符串表示)的最佳方式吗?

Thank you.

谢谢你！

Rails doesn't parse json parameters by default, you'll have to do it manually.

Rails默认不解析json参数，您必须手动解析。
