An idiomatic C++ client library for Web Security Scanner, a service that scans your Compute and App Engine apps for common web vulnerabilities.
While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.
Quickstart
The following shows the code that you'll run in the google/cloud/websecurityscanner/quickstart/ directory, which should give you a taste of the Web Security Scanner API C++ client library API.
The library automatically retries requests that fail with transient errors, and uses exponential backoff to backoff between retries. Application developers can override the default policies.

API C++ Client Library\n===========================================\n\nAn idiomatic C++ client library for [Web Security Scanner](https://cloud.google.com/security-command-center/), a service that scans your Compute and App Engine apps for common web vulnerabilities.\n\nWhile this library is **GA** , please note Google Cloud C++ client libraries do **not** follow [Semantic Versioning](https://semver.org/).\n\n### Quickstart\n\nThe following shows the code that you'll run in the `google/cloud/websecurityscanner/quickstart/` directory, which should give you a taste of the Web Security Scanner API C++ client library API. \n\n #include \"google/cloud/websecurityscanner/v1/web_security_scanner_client.h\"\n #include \"google/cloud/project.h\"\n #include \u003ciostream\u003e\n\n int main(int argc, char* argv[]) try {\n if (argc != 2) {\n std::cerr \u003c\u003c \"Usage: \" \u003c\u003c argv[0] \u003c\u003c \" project-id\\n\";\n return 1;\n }\n\n namespace websecurityscanner = ::google::cloud::websecurityscanner_v1;\n auto client = websecurityscanner::WebSecurityScannerClient(\n websecurityscanner::MakeWebSecurityScannerConnection());\n auto const project = google::cloud::Project(argv[1]);\n google::cloud::websecurityscanner::v1::ListScanConfigsRequest request;\n request.set_parent(project.FullName());\n for (auto c : client.ListScanConfigs(request)) {\n if (!c) throw std::move(c).status();\n std::cout \u003c\u003c c-\u003eDebugString() \u003c\u003c \"\\n\";\n }\n\n return 0;\n } catch (google::cloud::Status const& status) {\n std::cerr \u003c\u003c \"google::cloud::Status thrown: \" \u003c\u003c status \u003c\u003c \"\\n\";\n return 1;\n }\n\n### Main classes\n\nThe main class in this library is [`websecurityscanner_v1::WebSecurityScannerClient`](/cpp/docs/reference/websecurityscanner/2.11.0/classgoogle_1_1cloud_1_1websecurityscanner__v1_1_1WebSecurityScannerClient). All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock [`websecurityscanner_v1::WebSecurityScannerClient`](/cpp/docs/reference/websecurityscanner/2.11.0/classgoogle_1_1cloud_1_1websecurityscanner__v1_1_1WebSecurityScannerClient) when testing your application.\n\n### Retry, Backoff, and Idempotency Policies.\n\nThe library automatically retries requests that fail with transient errors, and uses [exponential backoff](https://en.wikipedia.org/wiki/Exponential_backoff) to backoff between retries. Application developers can override the default policies.\n\n### More Information\n\n- [Error Handling](https://cloud.google.com/cpp/docs/reference/common/latest/common-error-handling.html) - describes how the library reports errors.\n- [How to Override the Default Endpoint](/cpp/docs/reference/websecurityscanner/2.11.0/websecurityscanner-override-endpoint) - describes how to override the default endpoint.\n- [How to Override the Authentication Credentials](/cpp/docs/reference/websecurityscanner/2.11.0/websecurityscanner-override-authentication) - describes how to change the authentication credentials used by the library.\n- [Environment Variables](/cpp/docs/reference/websecurityscanner/2.11.0/websecurityscanner-env) - describes environment variables that can configure the behavior of the library."]]
