exchange.Encode

The exchange.Encode() function is used for signature encryption calculation.


    
    
    
exchange.Encode(algo, inputFormat, outputFormat, data)


    
    
    
exchange.Encode(algo, inputFormat, outputFormat, data, keyFormat, key)

Examples

BitMEX Position Change Push Notification (WebSocket Protocol) Example:


    javascript
    
    
function main() {
    var APIKEY = "your Access Key(Bitmex API ID)"
    var expires = parseInt(Date.now() / 1000) + 10
    var signature = exchange.Encode("sha256", "string", "hex", "GET/realtime" + expires, "hex", "{{secretkey}}")
    var client = Dial("wss://www.bitmex.com/realtime", 60)
    var auth = JSON.stringify({args: [APIKEY, expires, signature], op: "authKeyExpires"})
    var pos = 0
    client.write(auth)
    client.write('{"op": "subscribe", "args": "position"}')
    while (true) {
        bitmexData = client.read()
        if(bitmexData.table == 'position' && pos != parseInt(bitmexData.data[0].currentQty)){
            Log('position change', pos, parseInt(bitmexData.data[0].currentQty), '@')
            pos = parseInt(bitmexData.data[0].currentQty)
        }
    }
}


    python
    
    
import time
def main():
    APIKEY = "your Access Key(Bitmex API ID)"
    expires = int(time.time() + 10)
    signature = exchange.Encode("sha256", "string", "hex", "GET/realtime" + expires, "hex", "{{secretkey}}")
    client = Dial("wss://www.bitmex.com/realtime", 60)
    auth = json.dumps({"args": [APIKEY, expires, signature], "op": "authKeyExpires"})
    pos = 0
    client.write(auth)
    client.write('{"op": "subscribe", "args": "position"}')
    while True:
        bitmexData = json.loads(client.read())
        if "table" in bitmexData and bitmexData["table"] == "position" and len(bitmexData["data"]) != 0 and pos != bitmexData["data"][0]["currentQty"]:
            Log("position change", pos, bitmexData["data"][0]["currentQty"], "@")
            pos = bitmexData["data"][0]["currentQty"]


    c++
    
    
void main() {
    auto APIKEY = "your Access Key(Bitmex API ID)";
    auto expires = Unix() + 10;
    auto signature = exchange.Encode("sha256", "string", "hex", format("GET/realtime%d", expires), "hex", "{{secretkey}}");

    auto client = Dial("wss://www.bitmex.com/realtime", 60);
    json auth = R"({"args": [], "op": "authKeyExpires"})"_json;

    auth["args"].push_back(APIKEY);
    auth["args"].push_back(expires);
    auth["args"].push_back(signature);
    auto pos = 0;
    client.write(auth.dump());
    client.write("{\"op\": \"subscribe\", \"args\": \"position\"}");
    while(true) {
        auto bitmexData = json::parse(client.read());
        if(bitmexData["table"] == "position" && bitmexData["data"][0].find("currentQty") != bitmexData["data"][0].end() && pos != bitmexData["data"][0]["currentQty"]) {
            Log("Test");
            Log("position change", pos, bitmexData["data"][0]["currentQty"], "@");
            pos = bitmexData["data"][0]["currentQty"];
        }
    }
}

Returns

Type	Description
string	The `exchange.Encode()` function returns the calculated hash value encoding.

Arguments

Name	Type	Required	Description
algo	string	Yes	The `algo` parameter is used to specify the algorithm used in encoding calculation. Supported settings: "raw" (no algorithm), "sign", "signTx", "md4", "md5", "sha256", "sha512", "sha1", "keccak256", "sha3.224", "sha3.256", "sha3.384", "sha3.512", "sha3.keccak256", "sha3.keccak512", "sha512.384", "sha512.256", "sha512.224", "ripemd160", "blake2b.256", "blake2b.512", "blake2s.128", "blake2s.256". The `algo` parameter also supports: "text.encoder.utf8", "text.decoder.utf8", "text.encoder.gbk", "text.decoder.gbk" for encoding and decoding strings. The `algo` parameter also supports the "ed25519" algorithm. It supports using different hash algorithms, for example, the `algo` parameter can be written as "ed25519.md5", "ed25519.sha512", etc. Supports `ed25519.seed` calculation.
inputFormat	string	Yes	Used to specify the data format of the `data` parameter. The `inputFormat` parameter supports setting to one of: "raw", "hex", "base64", "string". "raw" means the data is raw data, "hex" means the data is `hex` encoded, "base64" means the data is `base64` encoded, "string" means the data is a string.
outputFormat	string	Yes	Used to specify the output data format. The `outputFormat` parameter supports setting to one of: "raw", "hex", "base64", "string". "raw" means the data is raw data, "hex" means the data is `hex` encoded, "base64" means the data is `base64` encoded, "string" means the data is a string.
data	string	Yes	The `data` parameter is the data to be processed.
keyFormat	string	No	Used to specify the data format of the `key` parameter. The `keyFormat` parameter supports setting to one of: "raw", "hex", "base64", "string". "raw" means the data is raw data, "hex" means the data is `hex` encoded, "base64" means the data is `base64` encoded, "string" means the data is a string.
key	string	No	The `key` parameter is used to specify the key used in signature calculation. You can use a plaintext string, or use `"{{accesskey}}"`, `"{{secretkey}}"` to reference the `accessKey` and `secretKey` configured in the `exchange` exchange object.
