发送数据
设定request头
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request addRequestHeader:@"Referer" value:@"http://www.dreamingwish.com/"];
使用ASIFormDataRequest POST表单
通常数据是以’application/x-www-form-urlencoded’格式发送的，如果上传了二进制数据或者文件，那么格式将自动变为‘multipart/form-data’
文件中的数据是需要时才从磁盘加载，所以只要web server能处理，那么上传大文件是没有问题的。
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; [request setPostValue:@"Ben" forKey:@"first_name"]; [request setPostValue:@"Copsey" forKey:@"last_name"]; [request setFile:@"/Users/ben/Desktop/ben.jpg" forKey:@"photo"];
数据的mime头是自动判定的，但是如果你想自定义mime头，那么这样：
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; // Upload a file on disk [request setFile:@"/Users/ben/Desktop/ben.jpg" withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"]; // Upload an NSData instance [request setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];
你可以使用addPostValue方法来发送相同name的多个数据（梦维：服务端会以数组方式呈现）：
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; [request addPostValue:@"Ben" forKey:@"names"]; [request addPostValue:@"George" forKey:@"names"]; [request addFile:@"/Users/ben/Desktop/ben.jpg" forKey:@"photos"]; [request addData:imageData withFileName:@"george.jpg" andContentType:@"image/jpeg" forKey:@"photos"];
PUT请求、自定义POST请求
如果你想发送PUT请求，或者你想自定义POST请求，使用appendPostData: 或者 appendPostDataFromFile:
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request appendPostData:[@"This is my data" dataUsingEncoding:NSUTF8StringEncoding]]; // Default becomes POST when you use appendPostData: / appendPostDataFromFile: / setPostBody: [request setRequestMethod:@"PUT"];
