Question

我遇到了一些困难，正在为我正在处理的后端提出请求。例如，我之前使用用户名创建的用户：“test23”及其密码：“ws0ei”在制作此JSON请求时非常有效：

self.username = @"test23";
self.password = @"ws0ei";

NSDictionary *jsonDictionary = @{@"action" : @"upload_profile_image",
                                    @"username" : self.username,
                                    @"password_hash" : [self md5HexDigest:self.password]};

NSString *requestString = [[NSString alloc]initWithData:[NSJSONSerialization dataWithJSONObject:jsonDictionary options:kNilOptions error:nil] encoding:NSUTF8StringEncoding];

NSString *escaped = [[NSString stringWithFormat:@"http://www.host.com/server.php?request=%@",requestString] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:escaped]];

- (NSString*)md5HexDigest:(NSString*)input
{
    const char* str = [input UTF8String];
    unsigned char result[CC_MD5_DIGEST_LENGTH];
    CC_MD5(str, strlen(str), result);

    NSMutableString *ret = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH*2];

    for (int i = 0; i<CC_MD5_DIGEST_LENGTH; i++)
    {
        [ret appendFormat:@"%02x",result[i]];
    }
    return ret;
}

但是，当使用我创建的“test32”用户名和相同的密码“ws0ei”测试相同的请求时，API会以

响应

{
    reason = "Invalid username/password";
    status = "image not uploaded";
}

我不知道问题是什么，我认为它与不正确的编码有关，或者与应用程序端的md5有关，而不是后端。

我很感激提供任何帮助。谢谢。 编辑：包括用户“test23”JSON字典，请求网址和请求响应的一些控制台日志，以及用户“test32”以向您显示它们是相同的“
