react-native中post请求

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)
                }
            });
