HttpQuery

Send an Http request.

Returns the response data of the request. If the return value is a JSON string, it can be parsed by the JSON.parse() function in the JavaScript language strategy, and by the json::parse() function in the C++ language strategy. If debug is set to true in the options structure, the return value is an object (JSON); if debug is set to false, the return value is a string. string, object

HttpQuery(url) HttpQuery(url, options)

Http request url. url true string Http request-related settings, for example, can be structured as follows:

{
    method: "POST",
    body: "a=10&b=20&c=30",
    charset: "UTF-8",
    cookie: "session_id=12345; lang=en",
    profile: "chrome_103",
    debug: false,
    headers: {"TEST-HTTP-QUERY": "123"},
    timeout: 1000
}

• profile: Used to simulate browser tls fingerprints. The supported settings include the following options: chrome_："chrome_103", "chrome_104", "chrome_105", "chrome_106", "chrome_107", "chrome_108", "chrome_109", "chrome_110", "chrome_111", "chrome_112", "chrome_117", safari_："safari_15_6_1", "safari_16_0", "safari_ipad_15_6", "safari_ios_15_5", "safari_ios_15_6", "safari_ios_16_0", firefox_："firefox_102", "firefox_104", "firefox_105", "firefox_106", "firefox_108", "firefox_110", "firefox_117", opera_："opera_89", "opera_90", "opera_91", zalando_："zalando_android_mobile", "zalando_ios_mobile", nike_："nike_ios_mobile", "nike_android_mobile", cloudscraper："cloudscraper", mms_："mms_ios", mesh_："mesh_ios", "mesh_ios_1", "mesh_ios_2", "mesh_android", "mesh_android_1", "mesh_android_2", confirmed_："confirmed_ios", "confirmed_android", okhttp4_："okhttp4_android_7", "okhttp4_android_8", "okhttp4_android_9", "okhttp4_android_10", "okhttp4_android_11", "okhttp4_android_12", "okhttp4_android_13",
• debug: When it’s set to true, the HttpQuery function call returns the full reply message. When it’s set to false, only the data in the Body of the reply message is returned.
• timeout: Timeout setting, set 1000 means 1 second timeout.
• charset: It supports transcoding of the requested response data, such as GB18030. It supports common encoding. All fields in this structure are optional, for example, the profile field can be left out.

An example of accessing the OKX public ticker API interface.

function main() {
    // Setting proxy and sending an http request for this time, no username, no password, this http request will be sent through the proxy
    HttpQuery("socks5://127.0.0.1:8889/http://www.baidu.com/")            

    // Setting proxy and sending an http request for this time, enter the user name and password, only the current call to HttpQuery takes effect, and then call HttpQuery again ("http://www.baidu.com") so that the proxy will not be used.
    HttpQuery("socks5://username:password@127.0.0.1:8889/http://www.baidu.com/")
}

# HttpQuery does not support Python, you can use the urllib/urllib2 library instead

void main() {
    HttpQuery("socks5://127.0.0.1:8889/http://www.baidu.com/");
    HttpQuery("socks5://username:password@127.0.0.1:8889/http://www.baidu.com/");
}

The HttpQuery function uses proxy settings.

The HttpQuery() function only supports JavaScript, C++ language, Python language can use the urllib library to send Http requests directly. The HttpQuery() is mainly used to access the interfaces of the exchange that do not require a signature, such as public interfaces like ticker information. The HttpQuery() can be used in the backtesting system to send requests (only GET requests are supported) to obtain data. Backtesting is limited to using 20 visits to different URLs, and HttpQuery() visits will cache data. When the same URL is accessed a second time, the HttpQuery() function returns the cached data and no more actual network requests occur.
