无法将索引 35 处的字节 [FC] 从指定代码页转换为 Unicode [英] Unable to translate bytes [FC] at index 35 from specified code page to Unicode

问题描述

我正在尝试将这样的对象发送到我的 REST API(使用 asp net core 构建)

I'm trying to send an object like this to my REST API(built with asp net core)

{
    "firstName":"tersü",
    "lastName":"asda"
}

这就是 SoapUI 中标题的外观:

And this is how the headers form SoapUI look:

 Accept-Encoding: gzip,deflate
Content-Type: application/json:charset=UTF-16
Host: localhost:4004
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

但是，我的 actionContext.ModelState 始终无效，因为它不能与元音变音一起使用.例外情况如下:

However, my actionContext.ModelState is always invalid because it can not work with the umlaute. The exception is the following:

无法将索引 35 处的字节 [FC] 从指定代码页转换为统一码

Unable to translate bytes [FC] at index 35 from specified code page to Unicode

如果有任何帮助，方法签名如下所示:

If it's any help, the method signature looks like this:

[ValidateUserData]
public async Task<IActionResult> Update(string userId, [FromBody] UpdateUserRequest updateRequest)

基本上代码从不重复

if (!actionContext.ModelState.IsValid)
{
    actionContext.Result = new BadRequestObjectResult(actionContext.ModelState);
}

在 [ValidateUserData] 属性中

我在这里错过了什么?

推荐答案

你正在发送用 utf-16 编码的字符串，但是告诉(在 Content-Type标头的字符集)它是 utf-8.

You are sending your string encoded in utf-16, but telling (in the Content-Type header's charset) it is utf-8.

utf-8中tersü的字节为:

74,65,72,73,C3,BC

但是 tersü(在 utf-16 中)包含字节(注意那里的 FC):

However tersü (in utf-16) contains the bytes (notice the FC there):

74,0,65,0,72,0,73,0,FC,0

(检查它in this fiddle)

所以它只是无法理解它.因此，要么在发送之前将您的字符串转换为客户端中的 utf-8，要么将 Content-Type 字符集设置为 utf-16.

So it just can't understand it. So either convert your string to utf-8 in your client before sending it, or set the Content-Type charset to utf-16 .
