请求示例 ​

Python ​

python
# coding=utf-8
import requests


# Get token
# <your_username> 以及 <your_password> 换成您的认证信息
auth_url = 'https://rqdata.ricequant.com/auth'
auth_json = {'user_name': '<your_username>', 'password': '<your_password>'}
token = requests.post(auth_url, json=auth_json).text

# Get data
data_url = 'https://rqdata.ricequant.com/api'
data_json = {'method': 'get_price', 'order_book_ids': ['10001941', '10001943'], 'start_date': '20190601', 'end_date': '20191011'}
headers = {'token': token}
response = requests.post(data_url, json=data_json, headers=headers)

print('resp: ', response.text)

R ​

注：R 中可以通过 reticulate 包直接调用 python 版本的 RQDATAC。

r
library(httr)

# Get token
# <your_username> 以及 <your_password> 换成您的认证信息
auth_url <- 'https://rqdata.ricequant.com/auth'
auth_json <- list(
        user_name = "your_username",
        password = "your_password"
    )
res <- POST(auth_url, body = auth_json, encode = "json")
tk <- content(res)

# Get data
data_url <- 'https://rqdata.ricequant.com/api'
data_json <- list(
        method = 'get_price',
        order_book_ids = list('000001.XSHE', '00005.XSHE'),
        start_date = '20190601',
        end_date = '20191011'
    )
res <- POST(data_url, body = data_json, add_headers(token=tk), encode="json")

MATLAB ​

我们提供 MATLAB 客户端产品(toolbox)，提供十分简洁易用的 API，调用方式类似于 python-rqdatac，请联系我们的销售或者致电公司官方电话获取。

PHP ​

PHP
<?php
function doPost($url, $post_data, $token){
    $headers =[
     'token:' . $token,
    ];
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_POST, 1);
    $data_string = json_encode($post_data);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data_string);
    $data = curl_exec($curl);
    curl_close($curl);
    $body = explode("\r\n\r\n", $data, 0);
    return $body;
}

// <your_username> 以及 <your_password> 换成您的认证信息
// Get token
$auth_url = "https://rqdata.ricequant.com/auth";
$auth_json = array(
    "user_name" => "your_username",
    "password" => "your_password",
);
$token = doPost($auth_url, $auth_json,  0);

// Get api data
$api_url = "https://rqdata.ricequant.com/api";
$api_json = array(
    "method" => "get_price",
    "order_book_ids" => array("000001.XSHE", "000005.XSHE"),
    "start_date" => "20190601",
    "end_date" => "20191011"
);

$data = doPost($api_url, $api_json, $token[0]);
print_r($data);
?>

C++ ​

使用cURL库执行请求

cpp
#include "iostream"

    string data((const char*) ptr, (size_t) size * nmemb);
    *((stringstream*) stream) << data;
    return size * nmemb;
}

const char *AUTH_URL = "https://rqdata.ricequant.com/auth";
const char *API_URL = "https://rqdata.ricequant.com/api";

string doPost(string json, string token) {
    CURL *newCurl = NULL;
    CURLcode response;
    newCurl = curl_easy_init();
    if ( newCurl != NULL ) {
        stringstream out;
        curl_slist *plist = curl_slist_append(NULL, "Content-Type:application/json");
        if(token != "") {
            plist = curl_slist_append(plist, ("token:" + token).c_str());
            curl_easy_setopt(newCurl, CURLOPT_URL, API_URL);
        } else {
            curl_easy_setopt(newCurl, CURLOPT_URL, AUTH_URL);
        }
        curl_easy_setopt(newCurl, CURLOPT_TIMEOUT, 3);
        curl_easy_setopt(newCurl, CURLOPT_HTTPHEADER, plist);
        curl_easy_setopt(newCurl, CURLOPT_POSTFIELDS, json.c_str());
        curl_easy_setopt(newCurl, CURLOPT_WRITEFUNCTION, receive_data);
        curl_easy_setopt(newCurl, CURLOPT_WRITEDATA, &out);
        curl_easy_setopt(newCurl, CURLOPT_SSL_OPTIONS, CURLSSLOPT_NATIVE_CA);
        response = curl_easy_perform(newCurl);
        curl_easy_cleanup(newCurl);
        newCurl = NULL;
        curl_slist_free_all(plist);
        plist = NULL;
        return out.str();
    }
}

int main() {
    // <your_username> 以及 <your_password> 换成您的认证信息
    // Get token
    const string authJson = "{\"user_name\": \"your_username\",\"password\": \"your_password\"}";

            "\"end_date\": \"20220722\""
        "}";
    string data = doPost(dataJson, token);
    cout << data << endl;
    return 0;
