在react-native中調用接口有3中方法,這會兒說一下fetch 的post請求示例
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", //請求方法
body: formData, //請求體
}
fetch(url, opts)
.then((response) => response.json())
.then((responseData) => {
// 注意,這裡使用了this關鍵字,為了保證this在調用時仍然指向目前元件,我們需要對其進行“綁定”操作
if (responseData.data) {
alert(JSON.stringify(responseData.data))
} else {
alert(responseData.message)
}
});
