如何在凌空库中将非英语单词作为文本部分添加到多部分请求中? [英] How to add non-English words as text part to multi-part request in volley lib?

问题描述

我有一个自定义的json请求类，可以将多部分文件上传到Android应用程序中的该类服务器，当我添加英文单词作为键和值(这些键和值是一部​​分)但我使用时，它可以正常工作任何阿拉伯语单词，它都会写入未知单词，例如'D * F * 9".
在将这些值写入ByteArrayOutputStream对象之前，一切正常，并且可以看到阿拉伯语单词.
这是所有类

I have a custom json request class to upload multi-part files to server this class in an Android application , it works fine when I add English words as keys and values(these keys and values are one part) but when I use any Arabic word, it writes unknown words like "'D*F*9".
Before I write these values to ByteArrayOutputStream object, every thing works fine, and I can see Arabic words.
This is the get Body Content Type method for the all class

@Override
public String getBodyContentType() {
    return "multipart/form-data;charset=UTF-8;boundary=" + boundary;
    //return "application/json; charset=UTF-8";
    //return "multipart/form-data; charset=UTF-8";
}

这是构建文本部分的build文本部分方法

Here is the build Text Part method to construct the text part

 private void buildTextPart(DataOutputStream dataOutputStream, String parameterName, String parameterValue) throws IOException {
    dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd);
    //dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"" + parameterName + "\"" + lineEnd);
    dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"" + parameterName + "\"" + lineEnd);
    dataOutputStream.writeBytes("Content-Type: text/plain; charset=UTF-8" + lineEnd);
    //dataOutputStream.writeBytes("Content-Type: application/json; charset=UTF-8" + lineEnd);
    Log.d("inside buildText", parameterName + " " + parameterValue);
    dataOutputStream.writeBytes(lineEnd);
    dataOutputStream.writeBytes(parameterValue + lineEnd);
}

这是我用来调试这些值的代码

And here the code I have used to debug these values

// just for debugging
        DataInputStream in = new DataInputStream(new ByteArrayInputStream  (bos.toByteArray()));
        Scanner scanner = new Scanner(in);
        while (scanner.hasNext()){
            Log.d("scanner ", scanner.next());
        }

我已经阅读过 RFC文档，但我不明白Content-的目的是什么-处置及其含义是什么.

I have read this RFC document but I can't understand what the purpose of Content-Disposition and what does its values mean.

我应该在此代码中进行哪些编辑才能正确获取阿拉伯语值?

What should I edit in this code to get the Arabic values correctly ?

我应该更改所有部分的内容类型，还是可以使每个部分都有其内容类型?

Should I change the content type in all parts or I can make every part has its content Type ?

有什么帮助吗?

推荐答案

最后我找到了答案，问题出在这一行

Finally I found the answer, the problem was in this line

dataOutputStream.writeBytes(parameterValue + lineEnd);

所以我将其更新为

So I updated it to

dataOutputStream.write(parameterValue.getBytes("utf-8"));
dataOutputStream.writeBytes(lineEnd);

获取所有非ASCII字符，现在它适用于所有语言.

to get all un ASCII characters, and now it works fine for all languages.
