ASIHttpRequest-发送数据

发送数据

设定request头

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];

[requestaddRequestHeader:@"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];

[requestsetPostValue:@"Ben"forKey:@"first_name"];

[requestsetPostValue:@"Copsey"forKey:@"last_name"];

[requestsetFile:@"/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

[requestsetFile:@"/Users/ben/Desktop/ben.jpg"withFileName:@"myphoto.jpg"andContentType:@"image/jpeg"

forKey:@"photo"];

 

// Upload an NSData instance

[requestsetData:imageDatawithFileName:@"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];

[requestaddPostValue:@"Ben"forKey:@"names"];

[requestaddPostValue:@"George"forKey:@"names"];

[requestaddFile:@"/Users/ben/Desktop/ben.jpg"forKey:@"photos"];

[requestaddData:imageDatawithFileName:@"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];

[requestappendPostData:[@"This is my data" dataUsingEncoding:NSUTF8StringEncoding]];

// Default becomes POST when you use appendPostData: / appendPostDataFromFile: / setPostBody:

[requestsetRequestMethod:@"PUT"];
