iOS 提交form表单,上传图片

之前不会用，总感觉很难，用后感觉不是太难，本文只是简单的讲一下怎么使用的，

//实例话对象

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

manager.requestSerializer.timeoutInterval = 20;

manager.responseSerializer = [[AFHTTPResponseSerializer alloc] init];

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];

//在请求头里 添加自己需要的参数

NSString *token = [[YXLoginStatusTool sharedLoginStatus] getTokenId];

[manager.requestSerializer setValue:token forHTTPHeaderField:@"id"];

//请求地址

NSString *URLSTR = @"";

[manager POST:URLSTR parameters:nil constructingBodyWithBlock:^(id _Nonnull formData) {

//转成data

self.justimagedata = UIImagePNGRepresentation(pickerImagePic);

//按照表单格式把二进制文件写入formData表单

[formData appendPartWithFileData:self.justimagedata name:@"" fileName:@"" mimeType:@"image/png"];

[formData appendPartWithFileData:self.backimagedata name:@"" fileName:@"" mimeType:@"image/png"];

} progress:^(NSProgress * _Nonnull uploadProgress) {

YXLog(@"++++%@+++",uploadProgress);

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

YXLog(@"responseObject == %@--++--%@----", [self getResponseObjcWithTask:responseObject],[self getRespodHeaderWithTask:task]);

if ([[self getRespodHeaderWithTask:task][@"Status"] isEqualToString:@"1"]) {

//成功

}else{

[YXAlearMnager ShowAlearViewWith:[self getRespodHeaderWithTask:responseObject][@"errorMsg"] Type:2];

}

[YXNetworkHUD dismiss];

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

[YXNetworkHUD dismiss];

YXLog(@"发送失败+++++%@++++%@",error,[self getRespodHeaderWithTask:task]);

[YXAlearMnager ShowAlearViewWith:@"头像更换失败" Type:2];

}];

//** 获取响应头 */

- (id)getRespodHeaderWithTask:(NSURLSessionTask *)task

{

NSHTTPURLResponse *respond = (NSHTTPURLResponse *)task.response;

return respond.allHeaderFields;

}

-(id)getResponseObjcWithTask:(id )responseObect{

id json;

NSError *error;

json = [NSJSONSerialization JSONObjectWithData:responseObect options:0 error:&error];

if (error) {

json = [[NSString alloc] initWithData:responseObect encoding:NSUTF8StringEncoding];

}

return json;

}
