unable to work with tokio in wasm32-unknown-unkown

[sigoden]

[target.'cfg(target_arch = "wasm32")'.dependencies]
reqwest = { version ="0.11", default-features = false, features = ["rustls-tls", "json"] }
tokio = { version = "1.0", default-features = false, features = ["net", "time"] }

If both tokio and reqwest dependencies exist, cargo build --target wasm32-unknown-unknown failed.
