[英]Posting Json to C# WebApi from React
I have a C# WebAPI action. 我有一个C#WebAPI操作。 I'm trying to post a string (but a json stringified string) to it using React.
我正在尝试使用React向其发布一个字符串(但是json字符串化字符串)。
For some reason I'm getting a 405 Method Not Allowed when the content type is aopplication/json. 由于某种原因,当内容类型为aopplication / json时,我得到了405 Method Not Allowed。 Urlencoded does get into PostTransaction, but body is always null.
Urlencoded确实进入了PostTransaction,但是body始终为null。 What do I need to change to be able to get json in PostTransaction?
我需要更改什么才能在PostTransaction中获取json?
WebConfig WebConfig
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
WebApiConfig WebApiConfig
config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/json"));
C# WebApi C#WebApi
[HttpPost]
[ActionName("PostTransaction")]
public string PostTransaction([FromBody] string body, string task, int key, string filters, string options)
{
// body is null from react when content type is urlencoded, but correct from jquery post
string returnString = "no data found";
if (body != null) {
returnString = body.ToString();
}
return returnString;
}
React 应对
var dataToSend = JSON.stringify({ param1: "value1", param2: "value2"});
fetch('http://localhosturl/PostTransaction',
{
method: 'post',
headers: {
'Accept': 'application/json, text/plain, */*',
'Content-Type': 'application/json'
},
body: dataToSend
})
.then(response => {
}
JQuery Post jQuery发布
var dataToSend = JSON.stringify({ param1: "value1", param2: "value2"});
$.post('http://localhosturl/PostTransaction', { '': dataToSend }).done(function (data) {
console.debug(data); // returned data from Web API
});
Thanks 谢谢
So the reason for the difference, is that I needed to convert the object in React, to a string, then stringify it again. 因此产生差异的原因是,我需要将React中的对象转换为字符串,然后再次对其进行字符串化。
My original post did do this, but at the same time I changed it from urlencoded to application/json, if I'd just originally changed it (see history) to application/json without removing the second stringify, it would have worked ok. 我的原始帖子确实做到了这一点,但是同时我将其从urlencoded更改为application / json,如果我只是将它(请参阅历史记录)最初更改为application / json而又不删除第二个stringify,那应该可以。
body: JSON.stringify(JSON.stringify(dataToSave))
This is so that when it's actually posted, it still has the escaped quotes. 这样一来,当它实际发布时,它仍然具有转义的引号。
