当我尝试执行请求时出现 IllegalArgumentException

发布于 2024-11-10 09:29:34 字数 609 浏览 4 评论 0原文

在我的代码中，我在向服务器执行请求的行中捕获了 IllegalArgumentException（索引 85 处查询中的非法字符）。使用的是构建为 patter 命令，另一个任务正确完成，但不是这样：

public CreateCommentTask(String barcodeId, String ball, String comment,
        String sign) {
    super(getApplicationUrl() + "?command=createComment" + "&barcodeId="
            + barcodeId + "&ball=" + ball + "&text=" + comment
            + "&sessionId=" + sign);
    // TODO Auto-generated constructor stub
}

所以，我只有地址和字符串格式的一些数据。我的应用程序在这行崩溃：

HttpResponse response = client.execute(task.createRequest());

你有什么想法吗？

In my code I catch IllegalArgumentException (Illegal character in query at index 85) in line where I execute request to server. Work with was build as patter Command, another tasks completes correct but not this:

public CreateCommentTask(String barcodeId, String ball, String comment,
        String sign) {
    super(getApplicationUrl() + "?command=createComment" + "&barcodeId="
            + barcodeId + "&ball=" + ball + "&text=" + comment
            + "&sessionId=" + sign);
    // TODO Auto-generated constructor stub
}

So, I have only adres and some data in string formate. My app crash in this line:

HttpResponse response = client.execute(task.createRequest());

Do you have any ideas?

我希望您需要对参数进行 URL 编码（最有可能是 comment 变量）。

编辑：您可以使用 java.net.URI 生成正确的查询。试试这个：

super(new URI(getApplicationUrl() + "?command=createComment" + "&barcodeId="
            + barcodeId + "&ball=" + ball + "&text=" + comment
            + "&sessionId=" + sign).toString());

I expect you need to URL encode the parameters (most probably the comment variable).

EDIT: you can use java.net.URI to generate the proper query. Try this:

super(new URI(getApplicationUrl() + "?command=createComment" + "&barcodeId="
            + barcodeId + "&ball=" + ball + "&text=" + comment
            + "&sessionId=" + sign).toString());

为什么不预先构建字符串并记录它呢？然后你就可以看到85是什么字符了。如果日志是这样的话，我保证问题就存在。如果您无法弄清楚原因，请将生成的字符串与日志的其余部分一起发布。

public CreateCommentTask(String barcodeId, String ball, String comment,
        String sign) {
    String query = getApplicationUrl() + "?command=createComment" + "&barcodeId="
            + barcodeId + "&ball=" + ball + "&text=" + comment
            + "&sessionId=" + sign;
    Log.d("HOLYCRAP", query);
    super(query);
}

Why don't you build the string beforehand and log it? Then you could see what character 85 is. I guarantee the problem is there if that's what the log says. If you can't figure out why, post the resulting string up, along with the rest of the log.

public CreateCommentTask(String barcodeId, String ball, String comment,
        String sign) {
    String query = getApplicationUrl() + "?command=createComment" + "&barcodeId="
            + barcodeId + "&ball=" + ball + "&text=" + comment
            + "&sessionId=" + sign;
    Log.d("HOLYCRAP", query);
    super(query);
}
