dart json.encode(data) 不能接受其他语言 [英] dart json.encode(data) can not accept other language

问题描述

我目前正在使用 dart 进行 Web 开发.使用模拟客户端实现服务.但是，会发生以下错误.下面的实现代码是一个内存中的web api服务，它继承了mockClient.调用client.send()并返回结果的代码.

I am currently doing web development with dart. Implemented service with mockclient. However, the following error occurs. The implementation code below is an in memory web api service that inherits mockClient. The code that calls client.send () and returns the result.

test_value 是 json.encode(数据)的结果.

test_value is the result of json.encode (data).

var test_value = '{"id": 1, "type": "Appetizer", "name": "한글"}';

     return Response (test_value, 200, headers: {'content-type': 'application / json'});

错误

Invalid argument(s): String contains invalid characters.
dart:convert                                           Latin1Codec.encode
package:http/src/response.dart 36:49                   new Response
package:basil/common/mock_rest/mock_recipe.dart 40:12  MockRecipe._handler

如果在上面的实现代码的名称中放了一个英文字符串，是没有错误的.为什么我在插入英文以外的字符时出现错误?

If you put an English string in the name of the above implementation code, there is no error. Why do I get an error when I insert a character other than English?

推荐答案

Response 类对正文使用 Latin-1 编码，除非指定了其他内容.这在构造函数本身中没有明确记录，但 body getter 上的文档确实表明了这一点.

The Response class uses Latin-1 encoding for the body unless something else is specified. This is not documented clearly on the constructor itself, but the documentation on the body getter does suggest this.

尝试在标题中设置字符集/编码，例如:

Try setting the charset/encoding in the header, e.g., as:

return Response(test_value, 200, headers: {
    HttpHeaders.contentTypeHeader: 'application/json; charset=utf-8'
});
