这个方法可以留着 ＋ 上传图片

上传图片：

 首先导入 afnemworking 这个库

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

 

 manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

 

 NSDictionary *parameters =@{@"参数1":@"value1",@"参数2":@"value2"、、、};

 

 NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:@"1.png"], 1.0);

 

 [manager POST:@"替换成你要访问的地址"parameters:parametersconstructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

 

 [formData appendPartWithFileData :imageData name:@"上传的图片参数" fileName:@"1.png" mimeType:@"image/jpeg"];

 

 } success:^(AFHTTPRequestOperation *operation,id responseObject) {

 

 NSLog(@"Success: %@", responseObject);

 

 } failure:^(AFHTTPRequestOperation *operation,NSError *error) {

 

 NSLog(@"Error: %@", error);

 

 }];

 

 这个方法可以上传图片，如果不用上传图片，可以把这句去掉[formData appendPartWithFileData :imageDataname:@"1"fileName:@"1.png"mimeType:@"image/jpeg"]

 

2.多张图片上传

 

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer]multipartFormRequestWithMethod:@"POST" URLString:url parameters:url参数 constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

        for (int i = 0; i<arrayImage.count; i++) {

            UIImage *uploadImage = arrayImage[i];

            [formData appendPartWithFileData:UIImagePNGRepresentation(uploadImage)name:[NSString stringWithFormat:@"参数%d",i+1] fileName:@"test.jpg"mimeType:@"image/jpg"];

        }

    } error:nil];

 

AFHTTPRequestOperation *opration = [[AFHTTPRequestOperationalloc]initWithRequest:request];   

opration.responseSerializer.acceptableContentTypes = [NSSetsetWithObject:@"text/html"];

[opration setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, idresponseObject) {

 

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

 

}
