推荐答案

终于下面的代码起作用了.问题出在 Body 参数上.

Finally The below code worked. The problem was with Body parameters.

fetch("http:/example.com", {method: "POST",
  body: "uname=value1&password=value2" // <-- Post parameters        
})
.then((responseData) => {
  AlertIOS.alert(
      "POST Response",
      "Response Body -> " + JSON.stringify(responseData.body)
  )
}).done();
       this.props.navigation.navigate("Home")
};
