java - 在 Intellij Idea 中使用 HashMap 设置了错误的键

Question

这是我的功能：

public String uploadImage(URL image,String message) throws Exception{
    HashMap<String,String> paramArgs=new HashMap<String,String>();
    paramArgs.put("fbImgPostURL","https://graph.facebook.com/me/photos");
    paramArgs.put("accessToken",accessGrant.getKey());
    paramArgs.put("imageURL",image.toString());
    paramArgs.put("message",message);
    return HttpPictureUpload.uploadImageViaHttpPost(paramArgs);
}

当我从intelliJ调试器调试它时，奇怪的是在行

paramArgs.put("accessToken",accessGrant.getKey());

显然，关键是accessToken。但调试器显示如下：

access_token=CAACKan8suD0BAKUZAyxLinmXw2PZAkmkhIhVZCojG1sE2QsW60CfQjZAJWyMbqc1Lxy1JmVmSyAU4eHOGSkHhqJSQE6tcORuXAkyFbok7WGyysgJYZC6QF6KZBPRwDwbPCE6JUJgKIGyXzZCfzVgnjHHuoZBLZBt2xXgZD

很明显，问题是我设置了一个不同的键名，但是在哈希映射中，设置了一个不同的键名，它实际上被传递给

HttpPictureUpload.uploadImageViaHttpPost(paramArgs);

这里的任何人都可以猜到发生了什么？

编辑： 这是我的uploadImageViaHttpPost()功能：

public static String uploadImageViaHttpPost(HashMap<String,String> keyParams){

    String in="Image Uploaded Successfully!!";
    try {
        HttpClient client = new HttpClient();
        PostMethod method = new PostMethod(keyParams.get("fbImgPostURL"));

        //Add any parameter if u want to send it with Post req.
        method.addParameter("accessToken", keyParams.get("accessToken"));
        method.addParameter("url",keyParams.get("imageURL"));
        method.addParameter("message",keyParams.get("message"));

        int statusCode = client.executeMethod(method);

        if (statusCode != -1) {
            in = method.getResponseBodyAsString();
        }

        System.out.println(in);

    } catch (Exception e) {
        e.printStackTrace();
    }
    return in;
}
