Put request with simple string as request body
提问by user672009
When I execute the following code from my browser the server gives me 400 and complains that the request body is missing. Anybody got a clue about how I can pass a simple string and have it send as the request body?
当我从浏览器执行以下代码时，服务器给了我 400 并抱怨请求正文丢失。有人知道如何传递一个简单的字符串并将其作为请求正文发送吗？
let content = 'Hello world'
axios.put(url, content).then(response => {
resolve(response.data.content)
}, response => {
this.handleEditError(response)
})
If I wrap content in [] it comes thru. But then the server receives it as a string beginning with [ and ending with ]. Which seems odd.
如果我将内容包装在 [] 中，它就会通过。但随后服务器将其作为以 [ 开头并以 ] 结尾的字符串接收。这看起来很奇怪。
After fiddling around I discovered that the following works
在摆弄之后我发现以下工作
let req = {
url,
method: 'PUT',
data: content
}
axios(req).then(response => {
resolve(response.data.content)
}, response => {
this.handleEditError(response)
})
But shouldn't the first one work as well?
但是第一个不应该也有效吗？

This works for me (code called from node js repl):
这对我有用（从节点 js repl 调用的代码）：
const axios = require("axios");
axios
.put(
"http://localhost:4000/api/token",
"mytoken",
{headers: {"Content-Type": "text/plain"}}
)
.then(r => console.log(r.status))
.catch(e => console.log(e));
Logs: 200
日志：200
And this is my request handler (I am using restify):
这是我的请求处理程序（我正在使用 restify）：
function handleToken(req, res) {
if(typeof req.body === "string" && req.body.length > 3) {
res.send(200);
} else {
res.send(400);
}
}
Content-Type header is important here.
Content-Type 标头在这里很重要。

I was having trouble sending plain text and found that I needed to surround the body's value with double quotes:
我在发送纯文本时遇到问题，发现我需要用双引号将正文的值括起来：
const request = axios.put(url, "\"" + values.guid + "\"", {
headers: {
"Accept": "application/json",
"Content-type": "application/json",
"Authorization": "Bearer " + sessionStorage.getItem('jwt')
}
})
My webapi server method signature is this:
我的 webapi 服务器方法签名是这样的：
public IActionResult UpdateModelGuid([FromRoute] string guid, [FromBody] string newGuid)

I solved this by overriding the default Content-Type:
我通过覆盖默认的 Content-Type 解决了这个问题：
const config = { headers: {'Content-Type': 'application/json'} };
axios.put(url, content, config).then(response => {
...
});
Based on m experience, the default Conent-Type is application/x-www-form-urlencoded for strings, and application/json for objects (including arrays). Your server probably expects JSON.
根据我的经验，默认的 Conent-Type 是 application/x-www-form-urlencoded 字符串，application/json 对象（包括数组）。您的服务器可能需要 JSON。

Have you tried the following:
您是否尝试过以下操作：
axios.post('/save', { firstName: 'Marlon', lastName: 'Bernardes' })
.then(function(response){
console.log('saved successfully')
});

axios.put(url,{body},{headers:{}})
axios.put(url,{body},{headers:{}})
example:
例子：
const body = {title: "what!"}
const api = {
apikey: "safhjsdflajksdfh",
Authorization: "Basic bwejdkfhasjk"
}
axios.put('https://api.xxx.net/xx', body, {headers: api})

This worked for me:
这对我有用：
export function modalSave(name,id){
console.log('modalChanges action ' + name+id);
return {
type: 'EDIT',
payload: new Promise((resolve, reject) => {
const value = {
Name: name,
ID: id,
}
axios({
method: 'put',
url: 'http://localhost:53203/api/values',
data: value,
config: { headers: {'Content-Type': 'multipart/form-data' }}
})
.then(function (response) {
if (response.status === 200) {
console.log("Update Success");
resolve();
}
})
.catch(function (response) {
console.log(response);
resolve();
});
})
};
}

simply put in headers 'Content-Type': 'application/json'and the sent data in body JSON.stringify(string)
只需放入标题'Content-Type': 'application/json'并将发送的数据放入正文中JSON.stringify(string)
