非法无引号字符((CTRL-CHAR，代码10))

Question

我在使用REST API时遇到问题。下面是我的休息客户端。它在服务调用时失败，错误:

org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Illegal unquoted character ((CTRL-CHAR, code 10)): has to be escaped using backslash to be included in string value; nested exception is com.fasterxml.jackson.core.JsonParseException: Illegal unquoted character ((CTRL-CHAR, code 10)): has to be escaped using backslash to be included in string value
at [Source: java.io.PushbackInputStream@62a8dd06; line: 11, column: 55]

当我在postman中使用相同的json字符串(打印在日志中)时，它可以工作。当我从客户端触发请求时，它失败了。

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("Authorization", "Basic " + base64Creds);
try {
request = mapper.constructRequest(txnRequest, params);
logger.debug(method + " Request: " + request);
ObjectMapper map = new ObjectMapper();
logger.debug(method + " Request in json format: " + 
map.writeValueAsString(request));

myRequest = new HttpEntity<MyRequest>(request, headers);
response = restTemplate.exchange(url, HttpMethod.POST, myRequest, MyResponse.class);
logger.debug(method + " response: " + response);
} catch(Exception ex) {
ex.printStackTrace();
}

任何帮助都非常感谢。

我切换到传统的HttpURLConnection来完成这个工作。通过这种方式，我可以用utf-8设置输入和输出格式，并且它工作了。我试图用rest模板做同样的事情，但问题仍然存在。因此，我要将客户端实现切换为HttpURLConnection
