程序流程
手機上傳文件至 proxy， proxy再轉發至CMA工程
1.手機中部分代碼如下：
1 private HttpResponse request(Url aUrl
2 , String aReqParam
3 , Hashtable aRequestProperties
4 , byte[] aPicData)
5 {
6 //send Action
7 this.iListener.httpListener(iInstance, HttpRequestListener.K_CREATE_CONNECT, null);
8
9 //send Action
10 this.iCancel = false;
11 this.iListener.httpListener(iInstance, HttpRequestListener.K_BEGIN_CANCEL, null);
12
13 //建立連接
14 if(!OpenConnection(aUrl))
15 {
16 return this.getErrResponse("無法建立連接.");
17 }
18
19 //send Action
20 this.iListener.httpListener(iInstance, HttpRequestListener.K_SENDING_DATA, null);

57 e.printStackTrace();
58 }
59 }
60
61 }else{

63 }
64 //********************
65 }else{
66 //不上傳圖片時的連接
67 dos.writeUTF(aReqParam);
68 }
69 }
70
71 //send Action
72 this.iListener.httpListener(iInstance, HttpRequestListener.K_WAITING_RESPONSE, null);
73
74 resCode = iHc.getResponseCode();
75
76 //do cancel

79
80 //get http header

105
106 String mimeType = iHc.getHeaderField("Content-Type");
107
108 if(mimeType == null)
109 {
110 mimeType = "";
111 //return this.getErrResponse("invalide mime type:"+mimeType);
112 }
113
114 String contectType = iHc.getHeaderField("Content-Type");
115 if(contectType!=null && contectType.trim().indexOf("vnd.wap.wml")>=0)
116 {
117 try{
118 Thread.sleep(1000);
119 }catch(Exception e){}

121 }
122

130 {
131 return this.getStreamResponse(is);
132 }
133 else
134 {

146 }
147 catch(ConnectionNotFoundException e)
148 {
149 return this.getErrResponse("ConnectionNotFoundException");
150 }
151 catch(IOException e)
152 {
153 if(iConnCount == 1)//表明是第一次失敗
154 {
155 HttpResponse res = new HttpResponse();
156 res.iErrStr = "IOException";
157 res.iTwiceConn = true;
158
159 if(this.iDebug)
160 System.out.println("twice!!!");
161 return res;
162 }
163 else

166 }
167 }
168 catch(Exception e)
169 {
170 return this.getErrResponse("Exception:1");
171 }
172 finally
173 {
174 this.destroyOutputStream(dos);
175
176 try
177 {
178 // if(is != null)
179 // {
180 // is.close();
181 // is = null;
182 // }
183 if (iHc != null)
184 {
185 iHc.close();
186 iHc = null;
187 }
188 }
189 catch (Exception e)
190 {
191 return this.getErrResponse("Exception:2");
192 }
193 }
194 }
其中，測試建立連接的方法如下：
1 private HttpConnection iHc = null;
2 private boolean OpenConnection(Url aUrl)
3 {
4 iHc = null;
5
6 try
7 {
8 if(!iIsProxy)//direct connection
9 {
10 String url = aUrl.iProtocol
11 + "://"
12 + aUrl.iHost;
13
14 if(aUrl.iPort != null)
15 url += (":" + aUrl.iPort);
16 if(aUrl.iPath != null)
17 url += ("/" + aUrl.iPath);
18
19 iHc = (HttpConnection) Connector.open(
20 url
21 , Connector.READ_WRITE,true);
22 }
23 else//proxy connection
24 {
25 iHc = (HttpConnection)Connector.open("http://10.0.0.172:80"
26 + "/"
27 + aUrl.iPath
28 , Connector.READ_WRITE, true);
29
30 if(aUrl.iPort != null)
31 {
32 iHc.setRequestProperty("X-Online-Host"
33 , aUrl.iHost + ":" + aUrl.iPort);
34 }
35 else
36 {
37 iHc.setRequestProperty("X-Online-Host"
38 , aUrl.iHost);
39 }
40 }
41
42 if(this.iHc != null)
43 return true;
44 else
45 return false;
46 }
47 catch(Exception e)
48 {
49 return false;
50 }
51 }
附：沒有文件上傳的方法，如下：
private HttpResponse request(Url aUrl
, String aReqParam
, Hashtable aRequestProperties)
{
//send Action
this.iListener.httpListener(iInstance, HttpRequestListener.K_CREATE_CONNECT, null);
//send Action
this.iCancel = false;
this.iListener.httpListener(iInstance, HttpRequestListener.K_BEGIN_CANCEL, null);
//建立連接
if(!OpenConnection(aUrl))
{
return this.getErrResponse("無法建立連接.");
}
//send Action
this.iListener.httpListener(iInstance, HttpRequestListener.K_SENDING_DATA, null);
InputStream is = null;
DataOutputStream dos = null;
int resCode = 0;
try
{
if(aReqParam != null)
iHc.setRequestMethod("POST");
else
iHc.setRequestMethod("GET");
this.iniRequestProperties(aRequestProperties);
if(aReqParam != null)
{
dos = iHc.openDataOutputStream();
dos.writeUTF(aReqParam);
}
//send Action
this.iListener.httpListener(iInstance, HttpRequestListener.K_WAITING_RESPONSE, null);
resCode = iHc.getResponseCode();
//do cancel
if(this.iCancel)
return null;
//get http header
int index = 0;
this.iResHttpHeader = new Hashtable();
while (true)
{
String key = iHc.getHeaderFieldKey(index++);
if(key == null)
{
break;
}
String field = iHc.getHeaderField(key);
iResHttpHeader.put(key, field);
}
//send Action
this.iListener.httpListener(iInstance, HttpRequestListener.K_END_CANCEL, null);
if(resCode == 200)
{……
