如何从服务器向客户端发送正文消息

Question

我有这个java服务器代码：

private Response createError(int code, String error) {
    logger.error(error);
    return Response.status(code).entity("{ \"errorMsg\": \""+error+"\"}").build();
}

和此客户端代码：

            function successCallback(response) {
                self.lastResults = response.data;
                self.filesToUpload.length = 0;
                deferred.resolve(response.data);
            }, function errorCallback(response) {
                console.log(response.data.errorMsg);
                self.filesToUpload.length = 0;
                deferred.reject(JSON.stringify(response.data.errorMsg));

            });

如何在客户端中访问服务器响应中输入的字符串？

我尝试失败：

response.getEntity()

response.entity
undefined

JSON.stringify(response)
"{"data":"<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html;charset=utf-8\"/>\n<title>Error 500 Request failed.</title>\n</head>\n<body><h2>HTTP ERROR 500</h2>\n<p>Problem accessing /api/VoicesUploader/uploadFiles.

Answer 1

尝试将.type（MediaType.TEXT_PLAIN）添加到您的响应中。

return Response.status(code).type(MediaType.TEXT_PLAIN).entity("{ \"errorMsg\": \""+error+"\"}").build();

Answer 2

您的响应不包含称为errorMsg的键。 这就是其中包含的全部内容：
