Build with WASI-HTTP Plug-in

The WASI-HTTP plug-in provides an implementation of the WASI HTTP proposal's outgoing-request interface, enabling WebAssembly modules to make outbound HTTP requests. It is built on top of libcpr, a modern C++ HTTP client library.

Build WasmEdge with WASI-HTTP Plug-in

To enable the WasmEdge WASI-HTTP plug-in, developers need to build WasmEdge from source with the cmake option -DWASMEDGE_PLUGIN_WASI_HTTP=ON.

The build system will automatically fetch and build libcpr via CMake's FetchContent, so no manual installation of dependencies is required.

cd <path/to/your/wasmedge/source/folder>
cmake -GNinja -Bbuild -DCMAKE_BUILD_TYPE=Release -DWASMEDGE_PLUGIN_WASI_HTTP=ON
cmake --build build
cmake --install build

备注

If the built wasmedge CLI tool cannot find the WASI-HTTP plug-in, you can set the WASMEDGE_PLUGIN_PATH environment variable to the plug-in installation path (such as /usr/local/lib/wasmedge/, or the built plug-in path build/plugins/wasi_http/) to try to fix this issue.

Then you will have an executable wasmedge runtime under /usr/local/bin and the WASI-HTTP plug-in under /usr/local/lib/wasmedge/libwasmedgePluginWasiHttp.so after installation.
