我有一些参数，我想POST表单编码到我的服务器:
{
'userName': 'test@gmail.com',
'password': 'Password!',
'grant_type': 'password'
}
我像这样发送我的请求(目前没有参数)
var obj = {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
},
};
fetch('https://example.com/login', obj)
.then(function(res) {
// Do stuff with result
});
如何在请求中包含表单编码的参数?
当前回答
在一个简单的函数中包装取回
async function post_www_url_encdoded(url, data) {
const body = new URLSearchParams();
for (let key in data) {
body.append(key, data[key]);
}
return await fetch(url, { method: "POST", body });
}
const response = await post_www_url_encdoded("https://example.com/login", {
"name":"ali",
"password": "1234"});
if (response.ok){ console.log("posted!"); }
其他回答
只使用
import qs from "qs";
let data = {
'profileId': this.props.screenProps[0],
'accountId': this.props.screenProps[1],
'accessToken': this.props.screenProps[2],
'itemId': this.itemId
};
return axios.post(METHOD_WALL_GET, qs.stringify(data))
你可以使用UrlSearchParams，然后像这样做一个toString():
这里有一个简单的方法:
fetch('https://example.com/login', {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
},
body: new UrlSearchParams(...{
'userName': 'test@gmail.com',
'password': 'Password!',
'grant_type': 'password'
})
.toString()
})
.then(res => {
//Deal with response:
})
只是这样做，UrlSearchParams做的把戏 这是我的代码，如果能帮到别人的话
import 'url-search-params-polyfill';
const userLogsInOptions = (username, password) => {
// const formData = new FormData();
const formData = new URLSearchParams();
formData.append('grant_type', 'password');
formData.append('client_id', 'XXXX-app');
formData.append('username', username);
formData.append('password', password);
return (
{
method: 'POST',
headers: {
// "Content-Type": "application/json; charset=utf-8",
"Content-Type": "application/x-www-form-urlencoded",
},
body: formData.toString(),
json: true,
}
);
};
const getUserUnlockToken = async (username, password) => {
const userLoginUri = `${scheme}://${host}/auth/realms/${realm}/protocol/openid-connect/token`;
const response = await fetch(
userLoginUri,
userLogsInOptions(username, password),
);
const responseJson = await response.json();
console.log('acces_token ', responseJson.access_token);
if (responseJson.error) {
console.error('error ', responseJson.error);
}
console.log('json ', responseJson);
return responseJson.access_token;
};
在一个简单的函数中包装取回
async function post_www_url_encdoded(url, data) {
const body = new URLSearchParams();
for (let key in data) {
body.append(key, data[key]);
}
return await fetch(url, { method: "POST", body });
}
const response = await post_www_url_encdoded("https://example.com/login", {
"name":"ali",
"password": "1234"});
if (response.ok){ console.log("posted!"); }
你可以使用FormData和URLSearchParams发布为application/x-www-form-urlencoded，示例如下:
如果你有一个表格:
<form>
<input name="username" type="text" />
<input name="password" type="password" />
<button type="submit">login</button>
</form>
您可以添加使用下面的JS来提交表单。
const form = document.querySelector("form");
form.addEventListener("submit", async () => {
const formData = new FormData(form);
try {
await fetch("https://example.com/login", {
method: "POST",
headers: {
"Content-Type": "application/x-www-form-urlencoded",
},
body: new URLSearchParams(formData),
});
} catch (err) {
console.log(err);
}
});
