From JQuery's documentation on ajax (http://api.jquery.com/jquery.ajax/):

从JQuery的ajax文档(http://api.jquery.com/jquery.ajax/):

Note: The W3C XMLHttpRequest specification dictates that the charset is always UTF-8; specifying another charset will not force the browser to change the encoding.

注意:W3C XMLHttpRequest规范规定字符集总是UTF-8;指定另一个字符集不会强制浏览器更改编码。

You're probably trying to send raw binary bytes from your protobuffer, which is not compatible with UTF-8.

您可能尝试从原始缓冲区发送原始二进制字节，这与UTF-8不兼容。

I'm not familiar with ProtoBuf.js, but from a little digging online it looks like there's a toBase64() method available for encoding the protobuf as a base64 string. Try using that method to get the data to send, and then on the server decode from base64.

我不熟悉神族。js，但是从在线挖掘来看，似乎有一个toBase64()方法可以用来将原buf编码为base64字符串。尝试使用该方法获取要发送的数据，然后在服务器上对base64进行解码。

Not sure if you found a solution but Google Protocol Buffers now come with a Javascript compiler.

不确定是否找到了解决方案，但是谷歌协议缓冲区现在附带了一个Javascript编译器。

Once you have built your object to send with the proto builder, You can send data using jQuery using the following:

一旦您构建了要与proto构建器一起发送的对象，您就可以使用以下方法使用jQuery发送数据:

    $.ajax({
        type: "PUT",
        url: "http://localhost:8088/user",
        data: user.serializeBinary(),
        success: function () {
            $("#message").text("User with key " + user.getApikey() + " saved");
        },
        contentType: "application/x-protobuf",
        processData: false
    });

ProcessData: false is necessary to avoid jQuery serialising the data in the background.

ProcessData:为了避免jQuery在后台序列化数据，必须使用false。
