Network Communication lesson 3 Analysis of the format of HTTP request data carrying Json data

Char szBuffer [1024] = {"authorJson: {loginAccount:\" admin\ "} & parmJson: {avell 1pr bRO 2m cJV 3}"}

The server parses the above message in the following form

The previous authorJson is the parameter, the so-called key, so pay attention to what is the json report with parameters

If it is json= {name:xiaoming,age:23}, you can use String json= request.getParameter ("json")

That is, the real data content in json format is only after the content.

So on the client side, the data should be stitched like this. At present, C++ Jsoncpp library is used to encapsulate the message.

Json::Value jsonLoginContext

JsonLoginContext ["loginAccount"] = "admin"

Json::Value jsonParamContext

JsonParamContext ["a"] = 1

JsonParamContext ["b"] = 2

JsonParamContext ["c"] = 3

Json::Value jsonParm

JsonParm.append (jsonParamContext)

Std::string strAu= "authorJson="

StrAu + = jsonLoginContext.toStyledString ()

StrAu + = "& parmJson="

StrAu + = jsonParamContext.toStyledString ()
