使用JSON String解析URL時捕獲到IllegalArgumentException

Question

我需要使用看起來像的JSON數據來制定一個url

http://someurl.com/passfail?parameter= {“data1”：“123456789”，“data2”：“123456789”}，我需要使用JBoss的ClientResponse傳遞它以獲得響應狀態。 我首先嘗試傳入文字字符串數據

ClientRequest clientrequest = new ClientRequest("http://someurl.com/passfail?parameter={\"data1\":\"123456789\",\"data2\":\"123456789\"});// assuming the "\" is formulated correctly

但它給了一個例外。 因此我也嘗試使用URL url = new URL（url），但它也不起作用。

我有以下異常嘗試嘗試，我感覺非常困難，我希望有人可以提供幫助。

拋出：IllegalArgumentException：

Answer 1

問題是您在URI字符串中傳遞非法字符： Java - 將String轉換為有效的URI對象

http://someurl.com/passfail?parameter={"data1":"123456789","data2":"123456789"}>

您需要“轉義”URI中的違規字符。

以下是一些替代方案：

• 我應該如何在JSON中轉義字符串？

• Java - 將String轉換為有效的URI對象

• 如何編碼URI參數值？

• 在Java中編碼URL查詢參數

• http://docs.oracle.com/javase/6/docs/api/java/net/URI.html

最后但並非最不重要：

• java.net.URLEncoder中

PS：你網址中的那個“>”怎么樣？

Answer 2

謝謝保羅，

我已經閱讀並對此進行了另一輪研究，我正在使用

String url ="http://someurl.com/passfail?parameter={"data1":"123456789","data2":"123456789"}";
String encodedURL = URIUtil.encodeQuery(url);

它給了我200的狀態，這是成功的。

我使用的API來自org.apache.commons.httpclient.util.URIUtil 。
