我正在尝试向 URL http://www.webservicex.net/globalweather.asmx?op=GetCitiesByCountry 发出 SOAP 请求 但我得到一个错误:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>System.Web.Services.Protocols.SoapException: Server was unable
to process request. ---> System.InvalidOperationException: Timeout
expired. The timeout period elapsed prior to obtaining a connection
from the pool. This may have occurred because all pooled connections
were in use and max pool size was reached.
at WebServicex.GlobalWeather.GetCitiesByCountry(String CountryName)
--- End of inner exception stack trace ---
</faultstring>
<detail />
</soap:Fault>
</soap:Body>
</soap:Envelope>
如果我在浏览器上调用 URI，它会起作用。我认为它在我的代码中遗漏了一些东西。
这是我正在做的:
public static String doSOAPPost() throws IOException{
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost =
new HttpPost("http://www.webservicex.net/globalweather.asmx?op=GetCitiesByCountry");
httpPost.addHeader("content-type", "text/xml");
StringBuffer buffer = new StringBuffer();
buffer.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
buffer.append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"");
buffer.append(" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">");
buffer.append("<soap:Body>");
buffer.append("<GetCitiesByCountry xmlns=\"http://www.webserviceX.NET\">");
buffer.append("<CountryName>Brazil</CountryName>");
buffer.append("</GetCitiesByCountry>");
buffer.append("</soap:Body>");
buffer.append("</soap:Envelope>");
StringEntity lEntity = new StringEntity(buffer.toString());
httpPost.setEntity(lEntity);
HttpResponse lHttpResponse = httpClient.execute(httpPost);
if (lHttpResponse.getStatusLine().getStatusCode() != HttpStatus.SC_OK){
throw new RuntimeException("HTTP problems posting method " +
lHttpResponse.getStatusLine().getReasonPhrase());
}
return EntityUtils.toString(lHttpResponse.getEntity());
}
我该如何解决这个错误？怎么了？
提前致谢。
最佳答案
我刚刚执行了你的代码，没有修改，我得到了这个响应:

错误信息:
System.InvalidOperationException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
看起来更像是后端异常(似乎服务器无法连接到 SQL 数据库)而不是与客户端相关的异常。因此，您尝试调用时服务器似乎出现了问题。
不过只有一个建议，请替换为:
HttpPost httpPost = new HttpPost(
"http://www.webservicex.net/globalweather.asmx?op=GetCitiesByCountry");
用这个:
HttpPost httpPost = new HttpPost(
"http://www.webservicex.net/globalweather.asmx");
