[Question]Android send json data to DotNet WCF Api

[eric010101]

I send json data to DotNet WCF Api，
but it has some Error : Bad Request 400

code:
JSON="[{"authkey":"kesy","id":"00AABBCC"}]"
req.InitializePost2(url,JSON.GetBytes("UTF8"))
req.SetContentType("application/json")
hc.Execute(req,1)

when i asked the WCF Api company
they sad i should Replace " to \" in the JSON format
like it:[{\"authkey\":\"kesy\",\"id\":\"00AABBCC\"}]

but when i do it,it`s not work
always get the same Error: Bad Request 400

what can i do?:sign0085:

1. I recommend you to use HttpUtils2 instead of HttpClient.
2. Use JSON library to generate the json string.
