Detailed Description

This mutable structure is used to configure any of the AWS clients. Default values can only be overwritten prior to passing to the client constructors.

Definition at line 47 of file ClientConfiguration.h.

Constructor & Destructor Documentation

◆ ClientConfiguration() [1/2]

Aws::Client::ClientConfiguration::ClientConfiguration ( )

◆ ClientConfiguration() [2/2]

Aws::Client::ClientConfiguration::ClientConfiguration ( const char *  profileName)

Create a configuration based on settings in the aws configuration file for the given profile name. The configuration file location can be set via the environment variable AWS_CONFIG_FILE

Member Data Documentation

◆ caFile

Aws::String Aws::Client::ClientConfiguration::caFile

If you certificate file is different from the default, you can tell clients that aren't using the default trust store where to find your ca file. If you are on windows or apple, you likely don't want this.

Definition at line 184 of file ClientConfiguration.h.

◆ caPath

Aws::String Aws::Client::ClientConfiguration::caPath

If your Certificate Authority path is different from the default, you can tell clients that aren't using the default trust store where to find your CA trust store. If you are on windows or apple, you likely don't want this.

Definition at line 178 of file ClientConfiguration.h.

◆ connectTimeoutMs

long Aws::Client::ClientConfiguration::connectTimeoutMs

Socket connect timeout. Default 1000 ms. Unless you are very far away from your the data center you are talking to. 1000ms is more than sufficient.

Definition at line 94 of file ClientConfiguration.h.

◆ disableExpectHeader

bool Aws::Client::ClientConfiguration::disableExpectHeader

Only works for Curl http client. Curl will by default add "Expect: 100-Continue" header in a Http request so as to avoid sending http payload to wire if server respond error immediately after receiving the header. Set this option to true will tell Curl to send http request header and body together. This can save one round-trip time and especially useful when the payload is small and network latency is more important. But be careful when Http request has large payload such S3 PutObject. You don't want to spend long time sending a large payload just getting a error response for server. The default value will be false.

Definition at line 211 of file ClientConfiguration.h.

◆ enableClockSkewAdjustment

bool Aws::Client::ClientConfiguration::enableClockSkewAdjustment

If set to true clock skew will be adjusted after each http attempt, default to true.

Definition at line 216 of file ClientConfiguration.h.

◆ enableEndpointDiscovery

bool Aws::Client::ClientConfiguration::enableEndpointDiscovery

Enable endpoint discovery For some services to dynamically set up their endpoints for different requests. Defaults to false, it's an opt-in feature. If disabled, regional or overriden endpoint will be used instead. If a request requires endpoint discovery but you disabled it. The request will never succeed.

Definition at line 232 of file ClientConfiguration.h.

◆ enableHostPrefixInjection

bool Aws::Client::ClientConfiguration::enableHostPrefixInjection

Enable host prefix injection. For services whose endpoint is injectable. e.g. servicediscovery, you can modify the http host's prefix so as to add "data-" prefix for DiscoverInstances request. Default to true, enabled. You can disable it for testing purpose.

Definition at line 223 of file ClientConfiguration.h.

◆ enableTcpKeepAlive

bool Aws::Client::ClientConfiguration::enableTcpKeepAlive

Enable TCP keep-alive. Default true; No-op for WinHTTP, WinINet and IXMLHTTPRequest2 client.

std::shared_ptr<Aws::Utils::Threading::Executor> Aws::Client::ClientConfiguration::executor

Threading Executor implementation. Default uses std::thread::detach()

Definition at line 167 of file ClientConfiguration.h.

◆ followRedirects

bool Aws::Client::ClientConfiguration::followRedirects

◆ httpLibOverride

Aws::Http::TransferLibType Aws::Client::ClientConfiguration::httpLibOverride

Definition at line 196 of file ClientConfiguration.h.

◆ httpRequestTimeoutMs

long Aws::Client::ClientConfiguration::httpRequestTimeoutMs

This is currently only applicable for Curl to set the http request level timeout, including possible dns lookup time, connection establish time, ssl handshake time and actual data transmission time. the corresponding Curl option is CURLOPT_TIMEOUT_MS defaults to 0, no http request level timeout.

Definition at line 82 of file ClientConfiguration.h.

◆ lowSpeedLimit

unsigned long Aws::Client::ClientConfiguration::lowSpeedLimit

Average transfer speed in bytes per second that the transfer should be below during the request timeout interval for it to be considered too slow and abort. Default 1 byte/second. Only for CURL client currently.

Definition at line 110 of file ClientConfiguration.h.

◆ maxConnections

unsigned Aws::Client::ClientConfiguration::maxConnections

Max concurrent tcp connections for a single http client to use. Default 25.

Definition at line 76 of file ClientConfiguration.h.

◆ profileName

Aws::String Aws::Client::ClientConfiguration::profileName

profileName in config file that will be used by this object to reslove more configurations.

Definition at line 130 of file ClientConfiguration.h.

◆ proxyScheme

Aws::Http::Scheme Aws::Client::ClientConfiguration::proxyScheme

Definition at line 122 of file ClientConfiguration.h.

◆ proxySSLCertPath

Aws::String Aws::Client::ClientConfiguration::proxySSLCertPath

Definition at line 143 of file ClientConfiguration.h.

◆ proxySSLCertType

Definition at line 163 of file ClientConfiguration.h.

◆ proxySSLKeyPath

Aws::String Aws::Client::ClientConfiguration::proxySSLKeyPath

Definition at line 192 of file ClientConfiguration.h.

◆ region

Aws::String Aws::Client::ClientConfiguration::region

AWS Region to use in signing requests. Default US_EAST_1

Definition at line 68 of file ClientConfiguration.h.

◆ requestTimeoutMs

long Aws::Client::ClientConfiguration::requestTimeoutMs

Socket read timeouts for HTTP clients on Windows. Default 3000 ms. This should be more than adequate for most services. However, if you are transfering large amounts of data or are worried about higher latencies, you should set to something that makes more sense for your use case. For Curl, it's the low speed time, which contains the time in number milliseconds that transfer speed should be below "lowSpeedLimit" for the library to consider it too slow and abort. Note that for Curl this config is converted to seconds by rounding down to the nearest whole second except when the value is greater than 0 and less than 1000. In this case it is set to one second. When it's 0, low speed limit check will be disabled. Note that for Windows when this config is 0, the behavior is not specified by Windows.
