Scene

Multipart/form-data is the way browsers upload files with forms. The most common scenario is that when writing an email, an attachment is added to the message, usually using a form, that is, uploading it to the server in multipart/form-data format. The Http server defines the format of uploaded data. The API address is http://10.10.10.10:80/restful/personInfo. The parameters are as follows:

Msg: {

"name": "fengyuzaitu"

"data": {

"id": "9191"

}

"sex": "1"

"type": "worker"

}

Code

Int PostHttpFormDataByLibCurl ()

{

Json::Value root

Root ["type"] = "worker"

Root ["sex"] = "1"

Root ["name"] = "fengyuzaitu"

Json::Value data

Data ["id"] = "9191"

Root ["data"] = data

Std::string strPostData = root.toStyledString ()

CURL * pCurlHandle = curl_easy_init ()

Std::string strResponseData

Curl_easy_setopt (pCurlHandle, CURLOPT_CUSTOMREQUEST, "POST")

Curl_easy_setopt (pCurlHandle, CURLOPT_URL, "http://10.10.10.10:80/restful/personInfo");"

Curl_easy_setopt (pCurlHandle, CURLOPT_WRITEFUNCTION, WriteResponseBody); / / set callback function

Curl_easy_setopt (pCurlHandle, CURLOPT_WRITEDATA, & strResponseData); / / set the parameters of the callback function to get feedback information

Struct curl_httppost * pFormPost = 0

Struct curl_httppost * pLastPtrFormPost = 0

Curl_formadd (& pFormPost, & pLastPtrFormPost, CURLFORM_COPYNAME, "msg", CURLFORM_COPYCONTENTS, strPostData.c_str (), CURLFORM_END)

Curl_easy_setopt (pCurlHandle, CURLOPT_HTTPPOST, pFormPost)

CURLcode nRet = curl_easy_perform (pCurlHandle)

If (0 = = nRet)
