Kami Platform Perdagangan Kuantum FMZ menyokong banyak bursa cryptocurrency dan merangkumi bursa arus perdana di pasaran. Walau bagaimanapun, masih ada banyak bursa yang tidak terkurung. Bagi pengguna yang perlu menggunakan bursa ini, mereka boleh mengaksesnya melalui Protokol Custom FMZ Quant. Bukan hanya terhad kepada bursa cryptocurrency, mana-mana platform yang menyokongRESTprotokol atauFIXProtokol juga boleh diakses.
Artikel ini akan mengambilRESTakses protokol sebagai contoh untuk menerangkan cara menggunakan protokol tersuai Platform Dagangan Kuantum FMZ untuk mengkapsul dan mengakses API pertukaran OKX. Kecuali dinyatakan sebaliknya, artikel ini merujuk kepada protokol tersuai REST.
Halaman untuk mengkonfigurasi pertukaran di Platform Dagangan Kuantum FMZ:
https://www.fmz.com/m/platforms/add
Strategy instance running on the docker -> Custom protocol program
.
Contohnya:http://127.0.0.1:6666/OKX
, program protokol tersuai dan docker biasanya dijalankan pada peranti yang sama (server), jadi alamat perkhidmatan ditulis sebagai mesin tempatan (localhost), dan port boleh digunakan sebagai port yang tidak diduduki oleh sistem.Strategy instance running on the docker -> Custom protocol program
.Strategy instance running on the docker -> Custom protocol program
.Tangkapan skrin konfigurasi pemalam OKX yang didedahkan dalam artikel adalah seperti berikut:
OKX pertukaran maklumat konfigurasi kunci rahsia:
accessKey: accesskey123 // accesskey123, these are not actual keys, just for demonstration
secretKey: secretkey123
passphrase: passphrase123
http://127.0.0.1:6666
. Program protokol tersuai boleh memproses laluan tertentu, seperti/OKX
.Apabila fungsi API platform (FMZ) dipanggil dalam strategi, program protokol tersuai akan menerima permintaan dari docker.
Halaman alat penyempurnaan:
function main() {
return exchange.GetTicker("LTC_USDT")
}
Menghantar fungsiexchange.GetTicker()
, program protokol tersuai menerima permintaan:
POST /OKX HTTP/1.1
{
"access_key":"xxx",
"method":"ticker",
"nonce":1730275031047002000,
"params":{"symbol":"LTC_USDT"},
"secret_key":"xxx"
}
exchange.GetTicker()
, method
adalahticker
.exchange.GetTicker()
, parameter yang berkaitan adalah:{"symbol":"LTC_USDT"}
.Apabila program protokol tersuai menerima permintaan dari docker, ia boleh mendapatkan maklumat seperti fungsi API platform (termasuk maklumat parameter) yang diminta oleh strategi, kunci pertukaran, dll berdasarkan maklumat yang dibawa dalam permintaan.
Berdasarkan maklumat ini, program protokol tersuai boleh mengakses antara muka pertukaran untuk mendapatkan data yang diperlukan atau melakukan operasi tertentu.
Biasanya antara muka pertukaran mempunyai kaedah seperti GET / POST / PUT / DELETE, yang dibahagikan kepada antara muka awam dan antara muka peribadi.
Program protokol tersuai menerima data tindak balas dari antara muka pertukaran dan memprosesnya lagi untuk membina data yang diharapkan oleh docker (digambarkan di bawah).GetTicker
, GetAccount
dan fungsi lain dalam pelaksanaan kelas CustomProtocolOKX dalam contoh protokol adat Python.
Apabila program protokol tersuai mengakses antara muka API pertukaran, melakukan operasi tertentu atau memperoleh data tertentu, ia perlu memberi masukan semula hasil kepada docker.
Data yang disalurkan kembali ke docker berbeza-beza mengikut antara muka yang dipanggil oleh strategi, dan mula-mula dibahagikan kepada dua kategori:
{
"data": null, // "data" can be of any type
"raw": null // "raw" can be of any type
}
data: Struktur khusus bidang ini berkaitan denganmethod
dalam permintaan yang diterima oleh program protokol tersuai, dan digunakan untuk membina struktur data akhirnya dikembalikan oleh fungsi API platform FMZ. Semua antara muka akan disenaraikan di bawah.
mentah: medan ini boleh digunakan untuk lulus dalam data mentah tindak balas antara muka API pertukaran, seperti struktur Ticker dikembalikan olehexchange.GetTicker()
medan Info struktur Ticker merakam dataraw
lapangan dandata
medan; beberapa fungsi API platform tidak memerlukan data ini.
{
"error": "" // "error" contains an error message as a string
}
kesalahan: maklumat kesilapan, yang akan dipaparkan dalam log ralat di kawasan log platform (FMZ) perdagangan langsung, alat pecahannya dan halaman lain.
Menunjukkan data tindak balas protokol tersuai yang diterima oleh program strategi:
// Tested in the debugging tool of the FMZ platform
function main() {
Log(exchange.GetTicker("USDT")) // The trading pair is incomplete, the BaseCurrency part is missing, and the custom protocol plug-in is required to return an error message: {"error": "..."}
Log(exchange.GetTicker("LTC_USDT"))
}
Di atas adalah proses ringkas program protokol tersuai yang mengambil bahagian dalam akses kepada (FMZ tidak dibungkus) pertukaran API. Proses ini hanya menerangkan proses apabila memanggilexchange.GetTicker()
Berikut akan menerangkan butiran interaksi semua fungsi API platform secara terperinci.
Platform ini merangkumi fungsi umum pelbagai pertukaran dan menyatukan mereka ke dalam fungsi tertentu, seperti fungsi GetTicker, yang meminta maklumat pasaran semasa produk tertentu. Ini adalah API yang pada dasarnya semua pertukaran mempunyai. Oleh itu, apabila mengakses antara muka API yang dikemas dalam platform dalam contoh strategi, docker akan menghantar permintaan ke program pemalam
POST /OKX HTTP/1.1
{
"access_key": "xxx",
"method": "ticker",
"nonce": 1730275031047002000,
"params": {"symbol":"LTC_USDT"},
"secret_key": "xxx"
}
Apabila memanggil fungsi API yang dikapsulkan platform FMZ yang berbeza dalam strategi (seperti GetTicker), format permintaan yang dihantar oleh docker ke protokol tersuai juga akan berbeza.method
danparams
. Apabila merancang protokol tersuai, menjalankan operasi tertentu mengikut kandungan kaedah. Berikut adalah senario permintaan-jawapan untuk semua antara muka.
Sebagai contoh, pasangan dagangan semasa adalah:ETH_USDT
Data yang docker menjangkakan protokol tersuai untuk bertindak balas adalah terutamanya ditulis dalam medan data, dan medan mentah juga boleh ditambah untuk merakam data asal antara muka pertukaran.

Peraturanexchange.IOfungsi digunakan untuk mengakses antara muka pertukaran secara langsung.
GET /api/v5/trade/orders-pending, parameters: instType=SPOT, instId=ETH-USDT
Sebagai contoh.
// Called in the strategy instance
exchange.IO("api", "GET", "/api/v5/trade/orders-pending", "instType=SPOT&instId=ETH-USDT")
medan kaedah:"__api_/api/v5/trade/orders-pending"
, medan kaedah bermula dengan _api, menunjukkan bahawa ini dipicu olehexchange.IOpanggilan fungsi dalam contoh strategi.

}
exchange.Go()
, exchange.GetRawJSON()
dan fungsi lain tidak perlu dikapsulkan, dan kaedah panggilan dan fungsi kekal tidak berubah.Selain menyokong semua fungsi bursa spot, bursa niaga hadapan juga mempunyai beberapa fungsi API yang unik untuk bursa niaga hadapan.
Untuk dilaksanakan
REST Custom Protocol - Akses kepada OKX pertukaran REST API antara muka, dilampirkan sebagai objek pertukaran spot. Melaksanakan permintaan antarmuka awam dan data tindak balas. Melaksanakan tandatangan antara muka persendirian, permintaan dan tindak balas data encapsulation. Contoh ini adalah terutamanya untuk ujian dan pembelajaran. antara muka lain menggunakan data yang disimulasikan untuk bertindak balas secara langsung kepada docker untuk ujian.
