Response:getResponseCode()

Mendapatkan kode status HTTP dari respons.

Tanda Tangan

getResponseCode(): number

Mengembalikan

number - Kode status HTTP (misalnya, 200, 404, 500)

Deskripsi

Metode getResponseCode() mengembalikan kode status HTTP dari respons server. Kode status menunjukkan apakah permintaan HTTP berhasil, gagal, atau memerlukan tindakan lebih lanjut.

Contoh

Pemeriksaan Kode Status Dasar

-- Make a request and check the status code
local response = Request("https://api.example.com/users"):get()
local statusCode = response:getResponseCode()

if statusCode == 200 then
    print("Request successful!")
    local data = response:getData()
    print("Response data: " .. data)
else
    print("Request failed with status: " .. statusCode)
end

Penanganan Kode Status Komprehensif

local response = Request("https://api.example.com/data"):get()
local status = response:getResponseCode()

if status >= 200 and status < 300 then
    -- Success responses (2xx)
    print("Request successful (2xx)")
    local data = response:getData()
    print("Data: " .. data)

elseif status >= 300 and status < 400 then
    -- Redirection responses (3xx)
    print("Redirection received (3xx)")
    print("Status: " .. status)

elseif status >= 400 and status < 500 then
    -- Client error responses (4xx)
    print("Client error (4xx)")
    local errorData = response:getData()
    if errorData and errorData ~= "" then
        print("Error details: " .. errorData)
    end

elseif status >= 500 and status < 600 then
    -- Server error responses (5xx)
    print("Server error (5xx)")
    local errorData = response:getData()
    if errorData and errorData ~= "" then
        print("Server error details: " .. errorData)
    end

else
    print("Unexpected status code: " .. status)
end

Penanganan Kode Status Spesifik

local response = Request("https://api.example.com/users/123"):get()
local status = response:getResponseCode()

if status == 200 then
    print("OK - Request successful")
    local userData = response:getData()
    print("User data: " .. userData)

elseif status == 201 then
    print("Created - Resource created successfully")
    local newResource = response:getData()
    print("New resource: " .. newResource)

elseif status == 204 then
    print("No Content - Request successful, no response body")

elseif status == 400 then
    print("Bad Request - Invalid request data")
    local errorInfo = response:getData()
    print("Error: " .. errorInfo)

elseif status == 401 then
    print("Unauthorized - Authentication required")

elseif status == 403 then
    print("Forbidden - Access denied")

elseif status == 404 then
    print("Not Found - Resource does not exist")

elseif status == 500 then
    print("Internal Server Error")
    local serverError = response:getData()
    print("Server error details: " .. serverError)

else
    print("Other status: " .. status)
    local otherData = response:getData()
    if otherData and otherData ~= "" then
        print("Response: " .. otherData)
    end
end

Kode Status Spesifik Metode HTTP

-- GET request
local getResponse = Request("https://api.example.com/data"):get()
local getStatus = getResponse:getResponseCode()

if getStatus == 200 then
    print("Data retrieved successfully")
elseif getStatus == 404 then
    print("Data not found")
end

-- POST request
local postResponse = Request("https://api.example.com/users")
    :setParameter("name", "John")
    :setParameter("email", "john@example.com")
    :post()

local postStatus = postResponse:getResponseCode()

if postStatus == 201 then
    print("User created successfully")
    local newUser = postResponse:getData()
    print("Created user: " .. newUser)
elseif postStatus == 400 then
    print("Invalid user data")
elseif postStatus == 409 then
    print("User already exists")
end

-- DELETE request
local deleteResponse = Request("https://api.example.com/users/123"):delete()
local deleteStatus = deleteResponse:getResponseCode()

if deleteStatus == 204 then
    print("User deleted successfully")
elseif deleteStatus == 404 then
    print("User not found")
end

Fungsi Pembantu Kode Status

function handleResponse(response)
    local status = response:getResponseCode()
    local data = response:getData()

    -- Success (2xx)
    if status >= 200 and status < 300 then
        print("✓ Request successful (" .. status .. ")")
        if data and data ~= "" then
            return data
        else
            return "Success (no content)"
        end
    end

    -- Client errors (4xx)
    if status >= 400 and status < 500 then
        print("✗ Client error (" .. status .. ")")
        if data and data ~= "" then
            print("Error details: " .. data)
        end
        return nil
    end

    -- Server errors (5xx)
    if status >= 500 and status < 600 then
        print("✗ Server error (" .. status .. ")")
        if data and data ~= "" then
            print("Server error: " .. data)
        end
        return nil
    end

    print("? Unexpected status: " .. status)
    return nil
end

-- Usage
local response = Request("https://api.example.com/data"):get()
local result = handleResponse(response)

if result then
    print("Operation successful: " .. result)
else
    print("Operation failed")
end

Logika Coba Ulang API

function makeRequestWithRetry(url, maxRetries)
    local retries = 0

    while retries < maxRetries do
        local response = Request(url):get()
        local status = response:getResponseCode()

        -- Success
        if status == 200 then
            return response:getData()
        end

        -- Don't retry on client errors (4xx)
        if status >= 400 and status < 500 then
            print("Client error (" .. status .. "), not retrying")
            return nil
        end

        -- Retry on server errors (5xx)
        if status >= 500 and status < 600 then
            retries = retries + 1
            print("Server error (" .. status .. "), retrying... (" .. retries .. "/" .. maxRetries .. ")")
            -- Wait before retrying (you might want to add a delay here)
        else
            retries = retries + 1
            print("Unexpected status (" .. status .. "), retrying... (" .. retries .. "/" .. maxRetries .. ")")
        end
    end

    print("Max retries reached, giving up")
    return nil
end

local data = makeRequestWithRetry("https://api.example.com/unstable", 3)
if data then
    print("Request succeeded: " .. data)
end

Kode Status HTTP Umum

Code	Category	Meaning	Typical Usage
200	Sukses	OK	Permintaan berhasil
201	Sukses	Created	Sumber daya dibuat
204	Sukses	No Content	Berhasil, tanpa body respons
400	Error Klien	Bad Request	Data permintaan tidak valid
401	Error Klien	Unauthorized	Autentikasi diperlukan
403	Error Klien	Forbidden	Akses ditolak
404	Error Klien	Not Found	Sumber daya tidak ada
409	Error Klien	Conflict	Konflik sumber daya
500	Error Server	Internal Server Error	Error sisi server
502	Error Server	Bad Gateway	Respons upstream tidak valid
503	Error Server	Service Unavailable	Server sementara tidak tersedia

Catatan

• Selalu periksa kode status sebelum memproses data respons
• Kode status distandarisasi di HTTP/1.1 dan HTTP/2
• Kode 2xx menunjukkan keberhasilan, 3xx menunjukkan pengalihan, 4xx menunjukkan error klien, 5xx menunjukkan error server
• Beberapa API mungkin menggunakan kode status kustom atau arti yang tidak standar
• Respons error (4xx, 5xx) mungkin berisi informasi yang berguna dalam body respons
• Error jaringan atau timeout dapat mencegah objek respons dibuat sama sekali
