在react-native中调用接口有3中方法,这会儿说一下fetch 的post请求示例

  let formData = new FormData();
formData.append("userName", this.state.userName);
formData.append("password", this.state.password);
formData.append("type", this.state.buttonType ? 1 : 2);
let url = config.serverUrl + "/User/LoginOrRegister/login";
let opts = {
method: "POST", //请求方法
body: formData, //请求体
}
fetch(url, opts)
.then((response) => response.json())
.then((responseData) => {
// 注意,这里使用了this关键字,为了保证this在调用时仍然指向当前组件,我们需要对其进行“绑定”操作
if (responseData.data) {
alert(JSON.stringify(responseData.data))
} else {
alert(responseData.message)
}
});
