比方说，我已授权“iam”-我所在地区的用户访问我的 API 中的资源路径。
我现在的问题是：
使用 CURL 在我的 API 上启用 iam 授权后如何进行测试？
我的资源路径之一如下所示：
https://my-api-id.execute-api.eu-central-1.amazonaws.com/dev/music/{id}
首先通过附加所需的策略，使用您的 IAM 用户权限获得对 API 网关的控制访问权限。 更多信息在这里
然后通过单击右上角下拉菜单中的
My Security Credentialscurl -X GET \
'https://my-api-id.execute-api.AWS_REGION.amazonaws.com/dev/music/{id}' \
-H 'Authorization: AWS4-HMAC-SHA256 Credential=YOUR_ACCESS_KEY/20210902/us-east-1/execute-api/aws4_request, SignedHeaders=content-type;host;x-amz-date, Signature=b28388012a84499650cf766bed595b51a8de988da0874140af78bd1775b95bb9' \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-H 'X-Amz-Date: 20210902T055703Z'
这将是您的 CURL 请求，但您必须先创建签名字符串请参阅此处
另外，我认为最好的方法是用代码发送请求，例如Python 正如官方文档示例中提到的。
例如，如果您的凭据已在本地设置，则此示例可用于向您的 REST API 发出 GET 请求：

# ************* TASK 1: CREATE A CANONICAL REQUEST *************

# Because almost all information is being passed in the query string,
# the order of these steps is slightly different than examples that
# use an authorization header.
# Step 1: Define the verb (GET, POST, etc.)--already done.
# Step 2: Create canonical URI--the part of the URI from domain to query
# string (use '/' if no path)
canonical_uri = '/'
# Step 3: Create the canonical headers and signed headers. Header names
# must be trimmed and lowercase, and sorted in code point order from
# low to high. Note trailing \n in canonical_headers.
# signed_headers is the list of headers that are being included
# as part of the signing process. For requests that use query strings,
# only "host" is included in the signed headers.
canonical_headers = 'host:' + host + '\n'

# Match the algorithm to the hashing algorithm you use, either SHA-1 or
# SHA-256 (recommended)
algorithm = 'AWS4-HMAC-SHA256'
credential_scope = datestamp + '/' + region + '/' + service + '/' + 'aws4_request'
# Step 4: Create the canonical query string. In this example, request
# parameters are in the query string. Query string values must
# be URL-encoded (space=%20). The parameters must be sorted by name.
# use urllib.parse.quote_plus() if using Python 3
canonical_querystring = 'Action=CreateUser&UserName=NewUser&Version=2010-05-08'
canonical_querystring += '&X-Amz-Algorithm=AWS4-HMAC-SHA256'

canonical_querystring += '&X-Amz-Date=' + amz_date
canonical_querystring += '&X-Amz-Expires=30'
canonical_querystring += '&X-Amz-SignedHeaders=' + signed_headers
# Step 5: Create payload hash. For GET requests, the payload is an
# empty string ("").
payload_hash = hashlib.sha256(('').encode('utf-8')).hexdigest()
# Step 6: Combine elements to create canonical request
canonical_request = method + '\n' + canonical_uri + '\n' + canonical_querystring + '\n' + canonical_headers + '\n' + signed_headers + '\n' + payload_hash
# ************* TASK 2: CREATE THE STRING TO SIGN*************
string_to_sign = algorithm + '\n' + amz_date + '\n' + credential_scope + '\n' + hashlib.sha256(canonical_request.encode('utf-8')).hexdigest()
# ************* TASK 3: CALCULATE THE SIGNATURE *************
# Create the signing key
signing_key = getSignatureKey(secret_key, datestamp, region, service)
# Sign the string_to_sign using the signing_key
signature = hmac.new(signing_key, (string_to_sign).encode("utf-8"), hashlib.sha256).hexdigest()
# ************* TASK 4: ADD SIGNING INFORMATION TO THE REQUEST *************
# The auth information can be either in a query string
# value or in a header named Authorization. This code shows how to put
# everything into a query string.
canonical_querystring += '&X-Amz-Signature=' + signature
# ************* SEND THE REQUEST *************
# The 'host' header is added automatically by the Python 'request' lib. But it
# must exist as a header in the request.
