如何使用AFNetworking通过POST发送图像作为参数（参数） [英] How to send image as parameters (param) with POST with AFNetworking

问题描述

我需要将图像作为参数发送，例如

I need to send image as param like

URl : some API 

params : {profileImage:string(file)}

仅在参数列表中，我必须将图像文件作为字符串发送。

Means in param list only i have to send image file as string.

我使用了以下代码。但它不起作用。

i used the below code. but it is not working.

NSData *dataImage = [[NSData alloc] init];
dataImage = UIImagePNGRepresentation(selectedImage);

NSString *stringImage = [dataImage base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

NSDictionary *params = {profileImage : stringImage}
NSString *url = [NetworkRoutes postProfileImageAPIWithMobileNumber:[PTUserDetails getMobileNumber]];

self.operationManager = [AFHTTPSessionManager manager];
self.operationManager.responseSerializer = [AFJSONResponseSerializer serializer]; //
[self.operationManager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"userName" password:@"some password"];

[self.operationManager POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

    NSError *error;
    if (![formData appendPartWithFileURL:[NSURL fileURLWithPath:path] name:@"file" fileName:[path lastPathComponent] mimeType:@"image/jpg" error:&error]) {
        NSLog(@"error appending part: %@", error);
    }
} progress:^(NSProgress * _Nonnull uploadProgress) {

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

}];

您的答案无需进行网络连接，也可以进行nsurlconnection

your answer no need to be in afnetworking , can also be in nsurlconnection

我要重新存储
{
响应：请上传图像文件
}

I am getting resposne { response :"Please upload image file" }

或

在所附的屏幕截图中，建议我如何操作。在邮递员中，我得到响应

Suggest me how to do like in the attached screen shot . In post man i am getting response

推荐答案

 NSData *imgData = UIImageJPEGRepresentation(image, 1.0);
    NSUInteger fileSize = [imgData length];
    if(fileSize>400000)
    {
        float size = (float)((float)400000/(float)fileSize);
        imgData = [NSData dataWithData:UIImageJPEGRepresentation(image,    size)];
    }

    NSString *imgProfilePic = [imgData base64Encoding];
    and then you can send this imgProfilePic to Webservice
