我正在尝试编写一个应用程序来将我的日程安排加载到我的 iOS 日历中。 但我在通过代码将我的用户通行证发送到服务器时遇到问题。 地址是:
http://78.39.179.41/delivery.dll
这是网页正文:
<html><head><title>Crew Delivery</title><style> body.bodydef {font-family: Tahoma; text-decoration: none; BACKGROUND-COLOR: #fdfff4; color: #000000; font-size: 9pt } input.def {text-transform: uppercase; font-family: Tahoma} </style></head><body class="bodydef" style="font-family: Tahoma">Welcome to crew scheduling delivery system <form Name="Schedule Request" method="POST" action=""> Crew Code : <input id="Text1" maxlength="4" name="Code" title="Code" style="width: 129px; text-transform: uppercase;" type="text" /><br /><br /> Crew Pass :   <input id="Text2" maxlength="4" name="Pass" title="Pass" style="width: 129px" type="password" /> <br /><br /> Table Type: <Select id="TableType" label="Select Table Type" Name="TableType"> <option>Brief</option> <option>Detail</option> </Select>  <br /><br />     <input id="Channel" Name="Channel" type="hidden" value="D2FB680ADAE641889F8B4159FA23F7C4"/> <input id="Submit1" style="width: 69px" type="submit" value="submit"/>     <input id="Reset1" style="width: 65px" type="reset" value="reset"/> </form></body></html>我尝试通过以下方式做到这一点:
NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://78.39.179.41/delivery.dll"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[theRequest setHTTPMethod:@"POST"];
NSString *postString = [NSString stringWithFormat:@"username=%@&password=%@"];
[theRequest setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
但我不知道我的 *postString 应该是什么字符串。
最佳答案
试试这个 -
NSURL *url = [NSURL URLWithString:@"http://78.39.179.41/delivery.dll"];
NSString *code = @"userx";
NSString *pass = @"xxxxx";
NSString *tableType = @"Brief"; //Brief or Detail
NSString *channel = @"655F23D118A847D9BD0544E0583677E7"; //some unique number generated by server
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request setHTTPMethod:@"POST"];
NSString *postString = [NSString stringWithFormat:@"Code=%@&Pass=%@&TableType=%@&Channel=%@", username, password, tableType, channel];
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *connection= [[NSURLConnection alloc] initWithRequest:request delegate:self];
在这段代码中，我们在 postString 中发送了 post 变量，我们使用的所有变量都是 html 中的表单元素。看到这个 -
<form Name="Schedule Request" method="POST" action="">
Crew Code :
<input id="Text1" maxlength="4" name="Code" title="Code" style="width: 129px; text-transform: uppercase;" type="text" />
Crew Pass :
<input id="Text2" maxlength="4" name="Pass" title="Pass" style="width: 129px" type="password" />
Table Type:
<Select id="TableType" label="Select Table Type" Name="TableType">
<option>Brief</option>
<option>Detail</option>
</Select>
<input id="Channel" Name="Channel" type="hidden" value="AB46BD275DA94020BEE071FEB971B6B9"/>
<input id="Submit1" style="width: 69px" type="submit" value="submit"/>
<input id="Reset1" style="width: 65px" type="reset" value="reset"/>
</form>
这是您的 html 表单，其中输入和选择标签具有主要信息，其中名称是发布变量的键，值是发布字符串的发布值。我们使用
分隔变量&
例子-
code=codevalue&pass=xxxx&type=any
