附加图片并发布到JSON API

如何使用图片创建帖子并将其作为来自iPhone应用的精选图片进行附加？附加图片并发布到JSON API

我使用WordPress的与JSON API plugin

我的网址创建后：< - Reference to this

http://www.example.com/api/create_post/?nonce=eea4bb4ce5&status=publish&title=Test&content=test%20content&categories=animals

试试这个。使用JSON POST方法。你可以像这样附加所有参数。

-(void)uploadImage 
{ 

    NSString *method = @""; 
    NSString *username = @""; 
    NSString *token = @""; 

    NSString *urlString = [NSString stringWithFormat:@"%@",@"yoururl"]; 

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; 
    [request setURL:[NSURL URLWithString:urlString]]; 
    [request setHTTPMethod:@"POST"]; 

    NSMutableData *body = [NSMutableData data]; 

    // file 
    NSData *imageData = UIImageJPEGRepresentation(imageView.image, 0.8); 
    NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; 
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"image\"; filename=\".jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[NSData dataWithData:imageData]]; 
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 

    // parameter username 
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"username\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[username dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 

    // parameter token 
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"auth_token\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[token dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 

    // // parameter method 
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"method\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[method dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 

    // close form 
    [body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 


    // setting the body of the post to the reqeust 
    [request setHTTPBody:body]; 

    // now lets make the connection to the web 
    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 

    NSLog(@"%@",returnString); 
    [returnString release]; 
}

希望这可以帮助你。

要充分填满你的要求，你需要发送图像文件的Web服务使用POST方法

首先选择图像从图片库或把它从相机，使数据该图片使用以下代码。

NSString *imgName = [NSString stringWithFormat:@"ImageTest"]; 
    NSData *imgData=UIImagePNGRepresentation(imgView.image); 

    NSString* urlstring = [NSString stringWithFormat:@"http://www.example.com/api/create_post/?nonce=eea4bb4ce5&status=publish&title=Test&content=test%20content&categories=animals&imageFile=%@",imgName]; 
    NSLog(@"URL >> %@",urlstring); 

    NSURL url = [NSURL URLWithString:[urlstring stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; 

    //===============================================   
    NSMutableURLRequest postRequest = [[[NSMutableURLRequest alloc] init] autorelease]; 
    [postRequest setURL:url]; 
    [postRequest setHTTPMethod:@"POST"]; 

    NSString boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; 
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
    [postRequest addValue:contentType forHTTPHeaderField: @"Content-Type"]; 

    NSMutableData *body = [[NSMutableData alloc] init]; 
    [postRequest addValue:contentType forHTTPHeaderField: @"Content-Type"]; 
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

imgName这是该代码非常重要对象它您需要在其中如上图所示Web服务来传递图像。

 [body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.png\"\r\n",imgName]] dataUsingEncoding:NSUTF8StringEncoding]]; //img name 
     [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 

     // Add Image imgData is Declare as Above. 
     [body appendData:[NSData dataWithData:imgData]]; 



    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [postRequest setHTTPBody:body]; 

    NSURLResponse *response; 
    NSError error = nil; 


    NSData* data = [NSURLConnection sendSynchronousRequest:postRequest returningResponse:&response error:&error]; 
    NSString *result=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
    // NSString * jsonRes = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil]; 


    NSLog(@"result = %@",[result JSONValue]);

它完美地与我合作！我希望你能从这里得到帮助！
