java.lang.IllegalArgumentException異常：無效的URI「/轉讓/ REST /字/ {名} /保護」：逃脫絕對路徑無效

Question

我有春天RESTful Web服務，這是工作的罰款與郵差（在Chrome插件）與URL（http://localhost:8080/Assignment/rest/words/ {名} /保護）需要命名爲「名」

1個參數和我的HttpClient用Java編寫過。用下面的代碼。

HttpClient client = new HttpClient(); 

PostMethod method = new PostMethod("http://localhost:8080/Assignment/rest/words/{name}/protection"); 
method.setParameter("name", "value"); 

    byte[] responseBody = null; 
    int statusCode = 0; 
    try { 
     // Executing method. 
     statusCode = client.executeMethod(method); 
     }catch(Exception e){} 
     // checking status code 
     if (statusCode != HttpStatus.SC_OK) { 
      System.err.println("Method failed: " + method.getStatusLine()); 
     } 

     // Reading response body. 
     responseBody = method.getResponseBody(); 

上 statusCode = client.executeMethod(method);其顯示錯誤

如下

請幫

Answer 1

很明顯，像大括號字符不會在URI允許的。您必須對該部分進行編碼。

嘗試這樣：

PostMethod method = new PostMethod(URIUtil.encodePath("http://localhost:8080/Assignment/rest/words/{name}/protection", "UTF-8")); 
method.setParameter("name", "value"); 

URIUtil爲commons-httpclient-3.1。

<dependency> 
     <groupId>commons-httpclient</groupId> 
     <artifactId>commons-httpclient</artifactId> 
     <version>3.1</version> 
    </dependency> 

Answer 2

其更好的使用URLBuilder第一然後分配內置的URL構造器參數：

URIBuilder uriBuilder =新URIBuilder （）;
