不在服务器上传我的图片当我的Android团队做同样的事情他们在服务器上使用这个Android PLZ帮助我
如果有人知道为什么我无法在服务器上获取我的图片，请提供帮助。

您的请求应该是：
NSMutableDictionary* _params = [[NSMutableDictionary alloc] init];
// how to send parameters with request that you ma need when also uload image //
[_params setObject:promotionalDocument forKey:[NSString stringWithFormat:@"promotionalDocument"]];
[_params setObject:mobile forKey:[NSString stringWithFormat:@"mobile"]];
// the boundary random string, that will not repeat in post data
NSString *BoundaryConstant = @"----------V2ymHFg03ehbqgZCaKO6jy";
// your server paramter for image
NSString* FileParamConstant = @"serverParamterForImage";
// the server url to which the image (or the media) is uploaded. Use your server url here
NSURL* requestURL = [NSURL URLWithString:@"your URL"];
// create request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setHTTPMethod:@"POST"];
// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", BoundaryConstant];
[request setValue:contentType forHTTPHeaderField: @"Content-Type"];
// post body
NSMutableData *body = [NSMutableData data];
// add params (all params are strings)
for (NSString *param in _params) {
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"%@\r\n", [_params objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}
// add image data
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
if (image) {
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:imageData];
[body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// set the content-length
NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[body length]];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
// set URL
[request setURL:requestURL];
// then you can use that request

我面临同样的问题。但我没有使用 NSMutableURLRequest 获得解决方案。您可以使用 AFNetworking 或 NSURLSessionUploadTask
<强> NSURLSessionUploadTask：
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
NSURL *url = YOUR_SERVICE_URL;
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:@"PUT"];
UIImage *image = [UIImage imageNamed:@"imageName"];
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
NSURLSessionUploadTask *taskUpload = [session uploadTaskWithRequest:request fromData:imageData completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSHTTPURLResponse *httpResp = (NSHTTPURLResponse*) response;
if (!error && httpResp.statusCode == 200) {
// Uploaded
} else {
NSLog(@"ERROR: %@ AND HTTPREST ERROR : %ld", error, (long)httpResp.statusCode);
}
}];
<强> AFNetworking：
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager POST:YOUR_SERVICE_URL parameters:YOUR_PARAMETER_DICTIONARY constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData)
{
[formData appendPartWithFormData:IMAGE_DATA name:YOUR_KEY_NAME];
} progress:^(NSProgress * _Nonnull uploadProgress)
{
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject)
{
NSLog(@"%@",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
}];
